Abstract
The utility model is a kind of gold mine Bottom of Stope cutting tunnel filling Concrete false bottom, it includes blotter（1）, blotter（1）Upper surface is covered with plastic film（2）, plastic film（2）Upper surface is equipped with reinforced liner（3）, in reinforced liner（3）On built concrete cushion by laying bricks or stones（4）.The utility model is applied to oper cylinler shallow hole shrinkage method Bottom of Stope as Concrete false bottom and cuts roadway construction, and certain supporting role can be played to upper lower burrs country rock, improves Stope safty, reduces the occurrence probability of roof fall accident.And it can press with more effectively controlling.
Description
Technical field
The utility model is related to a kind of gold mine Bottom of Stope to cut tunnel filling Concrete false bottom, is mainly used for bottomless
Column shallow hole shrinkage method stope.
Background technology
In gold mine mining, when carrying out back production using oper cylinler shallow hole shrinkage method, after a large amount of ore removals of stope, due to spine
Loss there are, still there are part ore, causing stope quadratic loss larger in stope the problem of.In back production waste fill ore deposit
During the corresponding bottom mineral building in room, it must stop back production when back production is to stope sill 4-5 meters away from top stage casing and set fore-set to stay, this
Sample can cause once to lose, the primary loss up to 10% or so.
Utility model content
The utility model is so the technical issues of solving is to provide a kind of gold mine Bottom of Stope cutting tunnel filling coagulation
Native vacation bottom, to reduce mining loss ratio and press with controlling.
The technical solution of the utility model is as follows：
Gold mine Bottom of Stope cuts tunnel filling Concrete false bottom, it is characterised in that it includes blotter, rubble pad
Layer upper surface is covered with plastic film, and plastic film upper surface is equipped with reinforced liner, has built concrete mats by laying bricks or stones on reinforced liner
Layer.
The reinforced liner includes bar-mat reinforcement, and the rail as rinforcement bar is fixed on bar-mat reinforcement, and two of rail are outer
End has been respectively fixedly connected with round steel.
The utility model has the positive effect that：
First, the utility model is applied as Concrete false bottom applied to oper cylinler shallow hole shrinkage method Bottom of Stope cutting tunnel
Work can play upper lower burrs country rock certain supporting role, improve Stope safty, and the generation for reducing roof fall accident is several
Rate.And it can press with more effectively controlling.
2nd, mining loss ratio is reduced, reduces ore resources waste, improves Economic Effects in Mine Enterprices.
3rd, reduce barren rock freight volume, reduce labor intensity.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of the reinforced liner of the utility model, the overlook direction which is Fig. 1.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Such as Fig. 1, the embodiment of the utility model includes blotter 1, and 1 upper surface of blotter is covered with plastic film 2, moulds
2 upper surface of material film is equipped with reinforced liner 3, has built concrete cushion 4 by laying bricks or stones on reinforced liner 3.
Such as Fig. 2, the reinforced liner 3 includes bar-mat reinforcement 31, the rail 32 as rinforcement bar is fixed on bar-mat reinforcement 31,
Two outer ends of rail 32 are fixedly connected with round steel 33 respectively.
Round steel 33 welds, the reinforcing bar of bar-mat reinforcement 31 is crisscross for being inserted into upper lower burrs between bar-mat reinforcement 31 and rail 32
It is tied up using iron wire at place.
The construction procedure of the utility model is as follows：
Preparation：After adopting quasi- engineering construction, Xian Duiqie chooses ore deposit in lane, chooses to design height；Simultaneously under stope one
Stubble big gun cloth eye.It caunches again to disk on ore removal Chuan Chuqie lanes.
Before construction ore removal wears Concrete false bottom, by design and construction reinforced liner 3, rail 32（The discarded rail of interception
Road）It is both needed to weld between round steel 33, rail 32 and bar-mat reinforcement 31.
Construction：Concrete false bottom carries out successively according to bottom-up sequence.First, in the rubble pad for cutting lane laying 200mm
Layer 1；2nd, plastic film 2 is laid on blotter 1；3rd, reinforced liner 3 is laid on plastic film 2；4th, in reinforced liner
Construct on 3 the concrete cushion 4 of 1m, at the same each ore removal of constructing wear and ore removal wear between concrete slope, reinforced liner 3 need to build by laying bricks or stones
In concrete.Rubble lumpiness is not greater than 50 × 50 ㎜ 2.
Maintenance：Curing period is five to seven days after Concrete false bottom is constructed, after Concrete false bottom intensity reaches requirement
It can dig up mine.
