Description

Stope roof falling space stowage unit and connect top method
Technical field
The invention belongs to winning equipment field, it is more particularly related to a kind of Stope roof emits and falls through Between stowage unit and connect top method.
Background technology
During coal mining activity, due to the exploitation continuous forward impelling of working face, top board exposed area increases the most therewith Greatly, cause top board that inbreak phenomenon often occurs, cause and produce the major accident stopping even personal injury.Coal Ore deposit accident investigation statistics shows, in all kinds of accidents, roof fall occupies larger specific gravity, and prior art solves coal The ore deposit commonly used timber of roof collapse phenomenon processes falling space, and this way operating efficiency does not reaches requirement, Also creating the waste of resource, timber process inbreak, it is difficult to ensure that the safety of working face, not only considerably increases The labour intensity of workman, have impact on the economic benefit in colliery, simultaneously it is difficult to ensure that the safety coal extraction of working face.
Summary of the invention
The technical problem to be solved be to provide a kind of ensure working face safety, it is ensured that this production face The Stope roof falling space stowage unit of back production.
Another technical problem to be solved by this invention is to provide a kind of use Stope roof falling space filling Equipment connects the method on top.
To achieve these goals, the technical scheme that the present invention takes by: a kind of Stope roof provided emits Fall through a stowage unit, and including gas bag, described gas bag is the parcel slush pulp that soft gas impermeable material is constituted The cavity of liquid, gas bag side is additionally provided with check-valves.
Preferably, gas bag is ellipsoid shape.
Preferably, soft gas impermeable material is plastics terylene air duct fabrics.
Preferably, liquid slurry is high-water material or Ma Lisan.
A kind of method using Stope roof falling space stowage unit to connect top: comprise the steps:
1) first check the gas situation at top that connects, confirm that gas density is up to standard;
2) with long, outstanding cash, work cash are looked for by pushing up to side only by instrument successively;
3) being inflated by gas bag, aeration quantity determines according to the size in inbreak cave;
4) then inflation gas bag is put into inbreak cave, liquid slurry pumping is filled with gas bag, treat that gas bag is full of Slip casting is stopped behind inbreak cave.
Preferably, gas density is less than 0.8%.
Preferably, liquid slurry is high-water material or Ma Lisan.
Using a kind of Stope roof falling space stowage unit of the offer of the present invention, including gas bag, gas bag is The cavity of the parcel liquid slurry that soft gas impermeable material is constituted, gas bag side is additionally provided with check-valves, once Finding that roof collapse can put into the gas bag of inflation, the amount of insufflation gas determines according to the volume of falling space, Gas bag is that soft gas impermeable material is constituted, and gas bag produces deformation according to the shape at roof collapse, inserts and emits Fall place's then fill liquid slurries in gas bag cavity, substantially reduces the construction time limit, saves time, expense Economical, it is ensured that the back production of this working face;Gas bag port is check-valves, slurries can be avoided to reveal and pollute stope.
Gas bag is ellipsoid shape, conveniently puts at roof collapse;Liquid slurry is high-water material or Ma Lisan, horse Beautiful dissipating is a kind of low viscosity, bi-component synthesis polyphosphazene polymer imines glue fat material, when using high pressure pouring, Time together with resin is mixed with catalyst, reaction or chance water generation expand, reaction itself or the polynary net of generation that foams The close elastomer of shape, job location is required low by Ma Lisan, as long as there being wind regime, after the reaction of this material, raw Becoming inertia foam, Ma Lisan has good anti-pressure ability, stands the motion on stratum, has lifetime long Feature;Meanwhile, Ma Lisan is swift in response, and substantially reduces the construction time limit, saves the time, does not affect life Produce, it is ensured that Safety of Coal Mine Production progress.
A kind of method using Stope roof falling space stowage unit to connect top, comprises the steps:
1) first check the gas situation at top that connects, confirm that gas density is up to standard;
2) with long, outstanding cash, work cash are looked for by pushing up to side only by instrument successively;
3) being inflated by gas bag, aeration quantity determines according to the size in inbreak cave;
4) then inflation gas bag is put into inbreak cave, liquid slurry pumping is filled with gas bag, treat that gas bag is full of Slip casting is stopped behind inbreak cave.
Use Stope roof falling space stowage unit of the present invention connects top method, with the gas bag filling generation of inflation Pile up the process realized Stope roof falling space for timber, efficiently solve puzzlement for a long time and connect top The difficult problem that dangerous height, intensity are big, inefficient, thus be truly realized construction and simplify, greatly subtract The light labour intensity of workman, decreases the waste of resource, it is ensured that the safe efficient back production of working face.
Connect gas density at top and be less than 0.8%, it is ensured that the safety of construction surface.
Below with reference to drawings and Examples, the present invention is described in detail.
Accompanying drawing explanation
Content expressed by width accompanying drawing each to this specification and the mark in figure are briefly described below:
Fig. 1 is the schematic diagram of the present invention a kind of Stope roof falling space stowage unit;
Fig. 2 is a kind of schematic diagram using Stope roof falling space stowage unit to connect top of the present invention.
Figure is labeled as: 1, gas bag;2, cavity;3, check-valves;4, liquid slurry;5, working face; 6, top board.
