Technical Field

The invention relates to the field of blasting, in particular to a water hole explosive filling device and a water hole explosive filling method.

Background

In the field of blasting, blast holes need to be drilled for filling explosives, when groundwater level is high, accumulated water is easy to be generated in the blast holes to form water holes, after the water holes are blown by using a hole blowing tool, water with a certain depth can be rapidly accumulated in the holes, and the blast holes cannot be filled with soluble powder explosives; even if the water-insoluble powdery emulsion explosive is used for filling, the phenomenon that the explosive floats on the liquid surface and cannot sink due to the fact that the apparent density of the explosive is less than that of liquid in a blast hole can also occur. At this time, the emulsion explosive with the density higher than that of water must be selected for filling the blast hole, and the method is used for filling the blast holeThe explosive is called as water-containing explosive, and the density of the packed explosive is greater than that of clear water and is generally 1.1-1.2 g/cm³。

When the water in the water hole is full or slightly lower than the orifice and the water in the hole is clean water, the emulsion explosive is gently put into the water, and the emulsion explosive can smoothly slide into the bottom of the hole. When the water in the tool water hole is used for stirring or the water in the hole is in a mud-water mixing state, the density of liquid in the hole is close to or even exceeds that of the emulsion explosive, and the emulsion explosive is in a suspension state in the hole and even floats on the hole opening and cannot sink; at the moment, tools such as a bamboo pole and a plastic pipe are needed to push the explosive into the bottom of the hole, in the process, the emulsion explosive is easy to cause package damage due to the tools or the friction between the emulsion explosive and the hole wall, the emulsion explosive is adhered to the hole wall and the tools after overflowing, the drift diameter of the hole is reduced, even the hole channel is blocked, and the blast hole is not filled successfully. The length of the plug may also be insufficient for design due to the presence of turbid liquid. Because the emulsion explosive can not discharge water in the hole, and the liquid belongs to incompressible substances, when the explosive explodes, the acting force of the detonation directly acts on the water instead of the wall of the rock hole, and the water carries energy to be flushed out along the hole opening, so that the explosion effect is not ideal. The liquid level is far away from the position of the orifice, and when the hand is not easy to contact the position, the impact force of the falling liquid level of the emulsion explosive can cause the damage of the explosive package, cause the direct hole plugging, increase the difficulty of processing the blast hole, even cause the scrapping of the blast hole, and cause unnecessary economic loss.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 5, in one embodiment, the water hole explosive loading device includes a high pressure air pipe 100 for providing high pressure air and an emulsion explosive releasing mechanism 200 made of non-metal material, which can prevent static electricity from being generated on the inner wall of the water hole and improve safety. The emulsion explosive release mechanism 200 is detachably mounted at the end of the high-pressure air pipe 100, so that the emulsion explosive release mechanism 200 can be conveniently connected to the high-pressure air pipe 100 when the explosive needs to be filled, and can be separated for storage when the explosive is not filled. The emulsion explosive releasing mechanism 200 is internally provided with an explosive bin 210 and a piston 220, the explosive bin 210 is used for placing the emulsion explosive 300, and the piston 220 is driven by high-pressure gas in the high-pressure air pipe 100 and pushes the emulsion explosive 300 to be separated from the explosive bin 210, so that the emulsion explosive is filled at the bottom of the water hole.

Specifically, when filling, the water hole explosive filling method based on the device of the embodiment comprises the following steps:

S3, releasing emulsion explosive: the height of the emulsion explosive releasing mechanism 200 is maintained, the high-pressure air pipe 100 is connected with compressed air, and the compressed air source can adopt an air compressor, namely, the high-pressure air pipe 100 is connected with the air compressor, and compressed air is provided for the high-pressure air pipe 100 through the air compressor. The compressed air pushes the piston 220 to move downwards, the piston 220 pushes the emulsion explosive 300 to be separated from the explosive bin 210, the piston moves downwards under the action of wind pressure to fill the bottom of the water hole and discharge water in the water hole, when the water in the water hole turns upwards, a hand holding the high-pressure air pipe 100 obviously feels that the weight of the high pressure is reduced, and the emulsion explosive is successfully released and successfully falls into the bottom of the water hole.

S4, extruding emulsion explosive: after emulsion explosive 300 entered into water hole bottom, because its external diameter is less than water hole internal diameter, still probably can float, in order to prevent it from floating out the page, can continue to keep the compressed air of certain pressure in high-pressure tuber pipe 100, high-pressure tuber pipe 100 moves down, extrude emulsion explosive 300 through piston 220, make emulsion explosive 300 take place to warp and contact with the pore wall, with emulsion explosive 300 compaction in water hole bottom, accomplish the loading of emulsion explosive in the water hole, when preventing to retrieve emulsion explosive release mechanism 200, emulsion explosive 300 floats out the liquid level.

S5, filling sand: and taking out the emulsion explosive releasing mechanism 200, slowly filling sand materials into the water holes, smoothly discharging water in the water holes out of the blast holes, and reducing the probability of punching the blast holes.

In some embodiments, the emulsion explosive release mechanism 200 includes a cylindrical pushing nipple 230 and a explosive bin nipple 240, the upper end of the pushing nipple 230 is connected with the high-pressure air pipe 100, the explosive bin nipple 240 is connected to the lower end of the pushing nipple 230, the explosive bin 210 is a cavity with an opening at the inner lower end of the explosive bin nipple 240, the upper end of the piston 220 is arranged in the pushing nipple 230, the lower end of the piston 220 is arranged in the explosive bin 210, when explosive is filled, compressed air enters the pushing nipple 230 and acts on the upper end of the piston 220 to push the piston 220 to move downwards, and the lower end of the piston 220 pushes the emulsion explosive 300 to be separated from the explosive bin 210 downwards.

In some embodiments, the upper end of the pushing nipple 230 is provided with a quick coupling 250 adapted to the high-pressure air pipe 100, and the quick coupling 250 is quickly connected to and detached from the high-pressure air pipe 100, so that the connecting and detaching efficiency is improved, and the use is more convenient.

In this embodiment, the tensile strength of the joint between the high pressure air duct 100 and the quick coupling 250 is less than that of the high pressure air duct 100. Can specifically set up the weak ring channel that the degree of depth is between 100 wall thickness 1/3 ~ 1/2 of high-pressure tuber pipe at high-pressure tuber pipe 100 end and quick-operation joint 250 junction, like this when emulsion explosive release mechanism 200 is blocked in the water hole, can pull high-pressure tuber pipe 100, breaks its weak ring channel department from, guarantees that high-pressure tuber pipe can take out smoothly. The weak annular groove can be arranged as a V-shaped groove or a U-shaped groove.

As an alternative of the foregoing embodiment, the high-pressure air pipe 100 may further be connected to a connector cooperatively connected with the quick connector 250 in a physical connection manner, and when the emulsion explosive releasing mechanism 200 is clamped in the water hole, the high-pressure air pipe 100 may be pulled to pull the high-pressure air pipe away from the physical connection with the connector, so as to ensure that the high-pressure air pipe can be taken out smoothly.

In some embodiments, the piston 220 comprises a piston rod 221, and a force-receiving piston 222 and a pushing piston 223 respectively connected to the upper end and the lower end of the piston rod 221, wherein the force-receiving piston 222 is disposed in a piston cavity 231 inside the pushing nipple 230 and is matched with the piston cavity 231, so that compressed air completely acts on the force-receiving piston 222 to push the emulsion explosive more rapidly, the pushing piston 223 is disposed in the explosive bin 210, and the outer diameter of the pushing piston 223 is smaller than the inner diameter of the explosive bin 210, so that the emulsion explosive is pushed more smoothly.

To ensure that the piston 220 has sufficient travel to push the emulsion explosive 300 completely out of the explosive cartridge 210, the height of the piston chamber 231 is set to be greater than the height of the emulsion explosive 300. Specifically, in order to adapt to the filling of emulsion explosives with more sizes, the maximum length of the common emulsion explosives can be set, and the height of the piston cavity 231 is set to be 0-5 cm larger than the maximum length of the common emulsion explosives.

In some embodiments, to ensure that emulsion explosive 300 does not fall out of explosive cartridge 210 by itself, the height of explosive cartridge 210 is set to be greater than the height of emulsion explosive 300, and the diameter of the inner hole of explosive cartridge 210 is smaller than the diameter of emulsion explosive 300, so as to ensure that emulsion explosive 300 does not fall out of explosive cartridge 210 by itself under the action of friction force after emulsion explosive 300 is plugged into explosive cartridge 210.
