Technical Field

The invention relates to the technical field of ionic rare earth mining engineering, in particular to an ionic rare earth in-situ leaching closure liquid collecting device and a using method thereof.

Background

The ionic rare earth mining method mainly adopts an in-situ mineral leaching process. The process principle is that a plurality of liquid injection holes (wells) are arranged at the top of an ore body (also a mountain body), an ore leaching agent is injected through the liquid injection holes (wells), and rare earth leachate is formed by exchanging the ore body with rare earth ions and flows downwards; and a closure liquid collecting project is arranged at the bottom of the ore body without an ore zone, and the rare earth leachate which flows down through seepage is collected. The intercepting liquid-collecting engineering is the most key process link for in-situ mineral leaching, the rare earth leachate can be leaked to underground soil and an underground water system due to incomplete liquid collection, rare earth resources are lost, and the environment is polluted, and the liquid-collecting rate is mostly 50-70% by adopting the conventional process method, so that the problem that the liquid-collecting rate is improved is solved. The in-situ leaching process is developed over twenty years, and a more-applied and mature method is to collect rare earth leaching liquid by adopting a diversion hole and a liquid collection roadway (or a liquid collection ditch). Arranging a plurality of layers of diversion holes at the bottom of the ore body in a staggered manner, wherein the hole diameter is about 20-30 cm, the distance between the two holes is about 1 m, the height difference of each layer is about 50 cm, and the bottom of each diversion hole is laid with an impermeable material; the longitudinal depth of the diversion holes is from more than ten meters to dozens of meters, the diversion holes slightly penetrate upwards (or downwards) and obliquely through the bottom of the ore body to form a dense intercepting net, and particularly relates to a Chinese south weathering crust leaching type rare earth ore leachate intercepting technology of CN108374097A, a system for improving the rare earth recovery rate of CN 106640082B and a rare earth mine liquid collecting system using the same. Meanwhile, the rare earth leaching solution collected by the diversion holes is collected in a liquid collection roadway (or a liquid collection ditch) and sent out to the next procedure for treatment.

The low liquid collection rate of the diversion holes due to interception mainly results from the following reasons and has the following defects: 1. because certain space exists between the diversion holes and the deviation of the horizontal (or vertical) position between the holes, a continuous cross-flow plane is difficult to form, so that a channel for downward seepage of the rare earth leaching solution cannot be completely blocked, and the worse the engineering quality is, the more serious the seepage is; 2. laying an impermeable material (such as quick-drying cement) at the lower bottom of the diversion hole, hardening to form a permanent project, intercepting and blocking a water seepage channel in the mountain after liquid collection and mining are finished (generally 3-5 months), changing and destroying the natural environment, and causing landslide and mountain collapse for a long time; 3. because the transverse depth of the diversion hole is from tens of meters to dozens of meters, the process of laying the anti-seepage material at the bottom of the hole is very complicated, and a large amount of manpower and material resources are spent; 4. a large amount of seepage-proofing materials are consumed by a large amount of flow guide holes, and the engineering cost is quite high.

After the liquid collecting pipe 4 after serial insertion is obliquely inserted into a V-shaped hole in a mine bottom non-ore zone, rare earth leachate 10 seeping from an ore body 12 can flow to the closure disc wing 1, liquid flowing to the closure disc wing 1 can flow to a drain hole 2 on the side wall of the liquid collecting pipe 4 through an inclined plane of the liquid collecting pipe, finally flows into the liquid collecting pipe 4 through the drain hole 2 and a drain net 7, then flows into the next group of liquid collecting pipes 4 through liquid collecting pipe orifices 6 of the liquid collecting pipe 4, and collected liquid flows to the outside of a mine through a plurality of groups of liquid collecting pipes 4 for collection and processing.

In the embodiment, a plurality of liquid collecting pipes 4 are connected in series, an inserting male head 5 positioned in a rear liquid collecting pipe 4 is inserted into a receiving female port 3 in a front liquid collecting pipe 4, the front end of a cut-off disc wing 1 on the rear liquid collecting pipe 4 is lapped on the rear end of the cut-off disc wing 1 in the front liquid collecting pipe 4, and a plurality of groups of cut-off liquid collecting devices are integrally and obliquely arranged in a V-shaped hole in a mine bottom mineral-free zone, rare earth leachate 10 seeped in a mineral body 12 flows to the corresponding cut-off disc wing 1, liquid flowing to the cut-off disc wing 1 flows to a drain hole 2 on the side wall of the liquid collecting pipe 4 through the inclined plane, finally flows to the liquid collecting pipe 4 through the drain hole 2 and a hole of a drain net 7, and in the process, a complete inclined plane (shown in figure 2) is formed between a plurality of groups of disc wings 1 on the same side, so that when liquid seeps to the upper part of the cut-off disc wings 1 and cannot flow into the liquid collecting pipe 4 through the drain hole 2 in time, the liquid on the upper intercepting dish wing 1 can flow downwards to the upper part of the next intercepting dish wing 1 along the complete inclined plane formed among the intercepting dish wings 1, and flows into the corresponding liquid collecting pipe 4 through the drain hole 2 corresponding to the intercepting dish wing, and so on, and finally flows into one liquid collecting pipe 4 among the liquid collecting pipes 4 and flows out through the liquid collecting pipe opening 5, meanwhile, because a complete inclined tubular structure is formed among the liquid collecting pipes 4, the liquid flowing into the liquid collecting pipe is easy to flow out from the liquid collecting pipe opening 5 at the lowest part along the inclined plane, and is difficult to deposit inside the liquid collecting pipe 4.

As shown in fig. 1 and 2, the front and rear ends of the intercepting dish wings 1 are provided with connecting holes 8, and after the two groups of intercepting dish wings 1 are overlapped up and down, the connecting holes 8 on the overlapped top ends of the two groups of intercepting dish wings 1 are correspondingly arranged up and down at the moment, so that the two groups of intercepting dish wings 1 which are overlapped up and down are locked and fixed by the bolt 9 on the connecting holes 8 so as to be convenient for moving, and the two groups of intercepting dish wings can not be separated under the condition of artificial intervention.

An application method of an ionic rare earth in-situ leaching closure liquid-collecting device comprises the following steps of constructing an inclined V-shaped hole in the bottom of an ore body without an ore belt, and then inserting a first closure liquid-collecting device into the V-shaped hole:

firstly, for the V-shaped hole which inclines upwards, a receiving female port 3 of a first intercepting liquid-collecting device enters in front, then a receiving female port 3 of a second intercepting liquid-collecting device is sleeved on an inserting male head 5 of the first intercepting liquid-collecting device, wherein the tilting end of a intercepting dish wing 1 in the first intercepting liquid-collecting device guides the front end of a intercepting dish wing 1 in the second intercepting liquid-collecting device to slide into the bottom of the intercepting dish wing, as shown in figure 3, the intercepting liquid-collecting outlet of the intercepting liquid-collecting device is arranged at a liquid-collecting channel 18, because the intercepting liquid-collecting device is inserted upwards into the V-shaped hole, the intercepting dish wing 1 of the upper intercepting liquid-collecting device is lapped on the top end of the intercepting dish wing 1 in the lower intercepting liquid-collecting device, rare earth leachate 10 seeped from an ore body 12 flows onto the corresponding intercepting dish wing 1, and liquid flowing onto the intercepting dish wing 1 flows to a drain hole 2 on the side wall of a liquid-collecting pipe 4 through the inclined plane of the intercepting liquid-collecting device, finally flows into the liquid collecting pipes 4 through the holes of the drainage holes 2 and the drainage net 7, and in the process, a complete inclined plane (shown in figure 2) is formed among a plurality of groups of the intercepting dish wings 1 on the same side, so that when liquid seeps above the intercepting dish wings 1 and cannot flow into the liquid collecting pipes 4 through the drainage holes 2 in time, the liquid on the intercepting dish wings 1 above can flow downwards to the upper part of the next group of the intercepting dish wings 1 along the complete inclined plane formed among the plurality of groups of the intercepting dish wings 1 and flows into the corresponding liquid collecting pipes 4 through the corresponding drainage holes 2, and so on, and finally flows into one liquid collecting pipe 4 of the plurality of groups of the liquid collecting pipes 4 and flows out into the liquid collecting channel 18 through the liquid collecting pipe openings 5.

Before the receiving female port 3 of the first intercepting and liquid-collecting device enters the V-shaped hole in advance, the receiving female port 3 needs to be blocked in advance, so that the situation that the ore soil at the high position of the V-shaped hole flows into the liquid collecting pipe 4 through the receiving female port 3 to block the V-shaped hole in the upward inserting process is avoided.

When an upward inclined V-shaped hole is met, if the male insertion head 5 of the first intercepting and liquid-collecting device enters in front, then the male insertion head 5 of the second intercepting and liquid-collecting device is inserted into the female receiving port 3 of the first intercepting and liquid-collecting device, wherein the upwarping end of the intercepting dish wing 1 in the second intercepting and liquid-collecting device slides to the top of the bottom end of the intercepting dish wing 1 in the first intercepting and liquid-collecting device, when liquid on the intercepting dish wing 1 at a high position cannot flow into the liquid-collecting pipe 4 through the drain hole 2 in time, the liquid on the intercepting dish wing 1 at the upper position can flow downwards to the upper part of the intercepting dish wing 1 at the next group along a complete inclined plane formed between the intercepting dish wings 1 at multiple groups, but the opening at the overlapped part between the two intercepting dish wings 1 at the high position is upward, so that when the liquid on the intercepting dish wing 1 at the high position flows to the dish wing 1 at the low position, the liquid flowing downwards flows into the V-shaped hole below the intercepting dish wing 1 and underground soil or underground soil from In the aqueous system, the liquid yield is lowered.

The plug-in male heads 5 in the front and rear two groups of intercepting and liquid-collecting devices are matched with the receiving female port 3, after the corresponding top ends of the intercepting dish wings 1 in the two groups of intercepting and liquid-collecting devices are overlapped up and down, bolts 9 are screwed on connecting holes 8 of the overlapped intercepting dish wings 1 to lock and reinforce the intercepting dish wings and the connecting holes, a plurality of groups of intercepting and liquid-collecting devices which are connected in series and inserted in a reinforcing mode are pushed into a V-shaped hole of an ore body, and then the steps are repeated.

Secondly, for the V-shaped hole which inclines downwards, an inserting male head 5 of a first intercepting and liquid-collecting device enters in front, then an inserting male head 5 of a second intercepting and liquid-collecting device is inserted into a bearing female port 3 of the first intercepting and liquid-collecting device, wherein the upwarping end of an intercepting dish wing in the second intercepting and liquid-collecting device guides the intercepting dish wing to slide to the top of the rear end of an intercepting dish wing 1 in the first intercepting and liquid-collecting device; as shown in fig. 3, in this case, the cut-off and liquid-collecting outlet of the cut-off and liquid-collecting device is in the roadway 14, since the cut-off and liquid-collecting device is inserted into the V-shaped hole downward, at this time, the cut-off disc wing 1 of the cut-off and liquid-collecting device located above is placed on the top end of the cut-off disc wing 1 of the cut-off and liquid-collecting device located below, then the rare earth leachate 10 seeped from the ore body 12 will flow to the corresponding cut-off disc wing 1, and the liquid flowing to the cut-off disc wing 1 will flow to the drain hole 2 of the side wall of the liquid-collecting tube 4 through the inclined plane, and finally will flow to the liquid-collecting tube 4 through the drain hole 2 and the drain net 7, and in this process, a complete inclined plane will be formed between the sets of cut-off disc wings 1 on the same side (as shown in fig. 2 specifically), so that when the liquid seeps to the upper side of the cut-off disc wing 1 and cannot flow into the liquid-collecting tube 4 through the drain hole 2, the drain hole The upper part of the flow dish wing 1 flows into the corresponding liquid collecting pipe 4 through the corresponding drain hole 2, and the like, and finally flows into one liquid collecting pipe 4 of the plurality of groups of liquid collecting pipes 4 and flows out into the roadway 14.

When a V-shaped hole which inclines downwards is met, if the receiving female port 3 of a first intercepting and liquid-collecting device enters in front, then the receiving female port 3 of a second intercepting and liquid-collecting device is sleeved on the inserting male head 5 of the first intercepting and liquid-collecting device, wherein the upwarping end of the intercepting dish wing 1 in the first intercepting and liquid-collecting device slides to the top of the bottom end of the intercepting dish wing 1 in the second intercepting and liquid-collecting device, when liquid on the intercepting dish wing at a high position cannot flow into the liquid-collecting pipe 4 through the drain hole 2 in time, the liquid on the intercepting dish wing 1 at the upper position can flow downwards to the upper part of the intercepting dish wing 1 at the next group along a complete inclined plane formed between the intercepting dish wings 1, but the opening at the overlapping part between the intercepting dish wings 1 at the high position faces upwards, so that the liquid on the intercepting dish wing 1 at the high position flows to the dish wing 1 at the low position, the liquid flowing downwards flows into the V-shaped hole below the intercepting dish wing from the gap between the intercepting dish wings 1 at the, resulting in a decrease in liquid yield.

The plug-in male heads 5 in the front and rear two groups of intercepting and liquid-collecting devices are matched with the receiving female port 3, after the corresponding top ends of the intercepting dish wings 1 in the two groups of intercepting and liquid-collecting devices are overlapped up and down, bolts 9 are screwed on the connecting holes 8 of the overlapped intercepting dish wings 1 to lock and reinforce the intercepting dish wings and the connecting holes, a plurality of groups of intercepting and liquid-collecting devices which are serially inserted for reinforcement are pushed into the V-shaped holes of the ore body, and then the steps are repeated.

The single intercepting and liquid-collecting device is in a butterfly tile shape (called as 'dish tile' for short), is processed and molded by injection molding or compression molding, and when the intercepting and liquid-collecting device is used, a plurality of intercepting and liquid-collecting devices are serially inserted to form a complete V-shaped guide groove (shown in figure 2), and then a plurality of V-shaped guide grooves are parallelly arranged and inserted into an ore body to form an intercepting surface.

When the dish tile is used in an in-situ ore leaching and liquid collecting project, a plurality of layers of V-shaped guide grooves are constructed around an ore body, at the bottom of a mountain body or in a roadway and penetrate through the bottom of the ore body; as shown in fig. 3, the second V-shaped guiding groove 17 is slightly lower than the first V-shaped guiding groove 16, so that the upper and lower V-shaped guiding grooves are constructed in a staggered manner, and the intercepting dish wing 1 of the intercepting and liquid-collecting device in the upper V-shaped guiding groove is expanded to be larger than the distance between the two adjacent V-shaped guiding grooves in the lower V-shaped guiding groove, so that the lower V-shaped guiding groove can receive the rare earth leaching solution 10 leaked from between the two adjacent V-shaped guiding grooves in the upper V-shaped guiding groove.

As shown in fig. 3 and 4, the in-situ leaching project is provided with a liquid injection hole 11 (well) net at the top of an ore body, and the liquid injection hole passes through a surface soil ore-free layer 13 and penetrates into the top of the ore layer; injecting an ore leaching agent into an ore body 12 through a liquid injection hole 11 (well), and percolating the ore body 12 to displace rare earth to form a rare earth leaching solution 10 and continuously percolating the rare earth leaching solution to an interception and liquid collection net (as shown in figure 4, the interception and liquid collection net is constructed by staggering a first layer of V-shaped diversion grooves 16 and a second layer of V-shaped diversion grooves 17, as shown in figure 2, the V-shaped diversion grooves are formed by serially inserting a plurality of interception and liquid collection devices); when the rare earth leaching solution 10 seeps into a first layer of diversion trench 16 combined by the dish tiles, a part of the rare earth leaching solution 10 seeps into a drain hole 2 of a liquid collecting pipe 4 in the intercepting liquid collecting device under the blocking of an intercepting dish wing 1 of the intercepting liquid collecting device in the first layer of V-shaped diversion trench 16, and flows into the liquid collecting pipe 4 through the drain hole 2 and a drain net 7; another small part of rare earth leaching solution 10 seeps to the second layer of V-shaped diversion trenches 17 along the space between two adjacent groups of first layer of V-shaped diversion trenches 16, and gradually converges into the drainage holes 2 of each intercepting and collecting device to enter the corresponding liquid collecting pipes 4; finally, the rare earth leaching solution 10 in the liquid collecting pipe 4 flows to the liquid collecting roadway 14 or the liquid collecting ditch 18.

And the drainage holes 2 and the drainage net 7 in the liquid collecting pipe 4 can effectively prevent mineral soil from entering the liquid collecting pipe 4, wherein when the rare earth leaching solution 10 seeps into the gap between the two adjacent groups of the V-shaped diversion grooves 16, the rare earth leaching solution 10 seeps downwards from the gap, and as the first layer of the V-shaped diversion grooves 16 and the second layer of the V-shaped diversion grooves 17 are installed in a staggered mode, and the intercepting dish wings 1 of the liquid intercepting and collecting device in the second layer of the V-shaped diversion grooves 17 are expanded to be larger than the distance between the two adjacent groups of the V-shaped diversion grooves 16, all the rare earth leaching solution 10 seeping downwards from the gap between the two adjacent groups of the V-shaped diversion grooves 16 is received by the second layer of the V-shaped diversion grooves 17. After the liquid collecting engineering is finished, the V-shaped diversion trench formed by serially inserting the intercepting liquid collecting devices can be pulled out one by one, the serially inserted intercepting liquid collecting devices are disassembled by unscrewing the bolts 9, and the intercepting liquid collecting devices are collected for the second ore block to collect liquid.

Compared with the prior art, the invention solves the following problems:

1. the lower layer of the intercepting liquid collecting net consisting of the V-shaped diversion grooves connected in series by the intercepting liquid collecting devices is used for intercepting and collecting the downward-permeating rare earth leaching liquid, so that the rare earth leaching liquid is prevented from seeping into underground soil or underground water below the rare earth leaching liquid from a gap between two adjacent groups of diversion holes in the prior art, the intercepting liquid collecting effect is remarkable, and the purpose of improving the intercepting liquid collecting effect is achieved.

2. The upper layer and the lower layer of the intercepting liquid collecting net consisting of the V-shaped diversion grooves connected in series by the intercepting liquid collecting device are used for intercepting and collecting the downward-seeping rare earth leachate, so that the rare earth leachate is prevented from seeping into underground soil and an underground water system, the environment is protected, the rare earth resource loss is reduced, and the utilization rate of water resources is improved.

3. After the mine drainage device is used, the V-shaped diversion groove formed by serially inserting a plurality of intercepting liquid collecting devices in the V-shaped hole in the mine can be drawn out, so that the permanent solid is prevented from being formed in the mine by an upper and a lower layers of intercepting liquid collecting nets formed by the V-shaped diversion grooves serially connected with the intercepting liquid collecting devices, and the problem of long-term interception of liquid seeping in the mine is solved.

4. The V-shaped diversion trench formed by inserting the plurality of the intercepting and liquid-collecting devices in series is inserted into the V-shaped hole in the mine for intercepting and collecting liquid, so that the operation is more convenient and the operation difficulty coefficient is small compared with the prior process of laying the anti-seepage material at the bottom in the diversion hole with the transverse depth of more than ten meters to dozens of meters, and meanwhile, the V-shaped diversion trench formed by the intercepting and liquid-collecting devices can be disassembled and recycled, so that the mining cost is reduced.
