Technical field

The present invention relates to underground mine exploitation engineering technical fields, more specifically, more particularly to it is a kind of be suitable on to The artificial false lane construction method of anchor slab during horizontally grouped top-coal drawing mining method mine.

Background technique

During metallic ore underground mining, artificial false lane is constructed there are certain objective factors needs to adjust down-hole mining System.Synthesis can be classified as two aspect: on the one hand due in range ore-rock be pooled out, formed goaf, original tunnel is destroyed Or completely disappear, cause the ore of lower step higher slice digging to be difficult to transport；On the other hand due to digging early period roadway layout system The limitation of system causes regional area that need to construct artificial false lane and carries out production adjustment, realizes the back production of mine safety stability and high efficiency.Currently In the mining methods of various artificial false lane structures, traditional artificial false lane structural shape is mostly concrete casting, brick coagulation Soil and precast concrete erection etc., long construction period, at high cost, large labor intensity become the artificial false lane structure application of restriction A key factor, seeking simple and feasible artificial tunnel, to construct new process significant.

Summary of the invention

It is an object of the invention in view of the above-mentioned problems of the prior art, provide a kind of simple process, highly-safe, Short time limit is constructed, and low in cost and engineering materials save anchor slab manually false lane construction method.

The technical solution adopted by the present invention is that: a kind of artificial false lane construction method of anchor slab,

Step 1: it is selected to construct position and trend according to the engineering demand of top ore body, and according to service function needed for the later period, Formulate bulk；

Step 2: according to position, trend, size, scene marks tunnel line, and according to mark line at a certain distance in top plate mine Column and bottom plate ore-rock carry out the Drilling of bolthole, and bolthole is symmetrical above and below, and on same plumb line；

Step 3: after bolthole Drilling, the installation of anchor pole is carried out, the anchor pole for being inserted into top plate ore pillar and bottom plate ore-rock passes through bundle It ties up the hanging reinforcing bar of reinforcing bar progress to connect to form internal vertical bar, while guaranteeing the inside vertical bar structure on same plumb line；

Step 4: in the inside vertical bar connected between top plate ore pillar and bottom plate ore-rock, then equidistantly pass through bundled fixed both ends Threaded short muscle；

Step 5: according to field fabrication iron plate, and perforating on iron plate, and short muscle passes through the hole on iron plate, passes through pallet and nut Carry out the fixation of iron plate；

Step 6: after iron plate is fixed, space processed is enclosed to iron plate inside and carries out concreting；

Step 7: after concrete setting, the packing job in layering region to be filled can be carried out；

Step 8: after body solidification to be filled, higher slice region orebody mining is carried out, while at the reserved security personnel in lane position top Ore pillar, safety pillar and concreting anchor slab constitute artificial false lane.

Preferably, step 2 anchor pole eyelet depth is that project situation takes 1 ~ 1.5m；It is divided into 0.5 between bolthole ~ 1.2m。

Preferably, anchor pole described in step 3 is resin anchor, 0.5 ~ 1.5m of anchor pole protruded length.

Preferably, on the hanging reinforcing bar that step 4 connects between top plate ore pillar and bottom plate ore-rock, lead at a certain distance Cross the short muscle of bundled fixed TBE (threaded both ends), 0.2 ~ 0.6m of short muscle length.

Preferably, step 4 is formed with step 5 by the fixed each iron plate of threaded short muscle, pallet and nut Concreting space, can be rotated by control nut between deep-controlled two iron plate and pour thickness.

Preferably, concreting can carry out the pouring of gradation from bottom to top in step 6.

Preferably, in step 8 safety pillar with a thickness of 2 ~ 4m.

Compared with prior art, the invention has the following advantages that

The present invention uses hanging connection anchor pole, and encloses progress concrete in space processed using the fixed iron plate of short muscle, pallet and nut and pour It builds and what is formed pours anchor slab, and it is good artificial quickly, simply to have constructed with the safety pillar at top security performance together False lane.Using the fixed iron plate of short muscle, pass through the controllable range for enclosing space processed of the rotation depth of thread；It can be consolidated using iron plate junction Determine multilayer iron plate, ensure that the closed of space；The infiltration of inside and outside slurry is prevented, structure is reliable, ensure that artificial false lane mined out Safety and stability in area's filling and subsequent production use process.

In conclusion present invention process is simple, highly-safe, and short time limit is constructed, low in cost, engineering materials save, and apply The artificial false lane intensity that work is completed is high, security performance is good, especially suitable for ore and rock stability preferably, ore value it is higher, on Into horizontally grouped top-coal drawing mining method, artificial vacation lane is constructed.
