Abstract
The utility model one is anti-breaks type gob side entry retaining filling air bag, comprise the diamond mesh covered outside cuboid flexible rubber air bag and cuboid flexible rubber air bag, it is characterized in that diamond mesh is covered in the outside of cuboid flexible rubber air bag uniformly, diamond mesh is woven by steel wire or iron wire to form.Flexible rubber air bag is identical with working face mining height, width is 1-5 rice, length is 1-10 rice, the diamond mesh covered outward can prevent spoil scratch cuboid flexible rubber air bag, during filling, cuboid flexible rubber air bag is easy to connect top, can close the goaf in time, and construction technology is simple, safe and reliable, operating efficiency is high, the filled wall formed is economical and practical, is suitable for constructing fast of filled wall bodies of gob-side retained entries.
Description
Technical field
The utility model is that the mining anti-of a kind of high-efficiency and economic breaks type gob side entry retaining filling air bag, is used for replacing traditional filled wall bodies of gob-side retained entries, is particularly useful for the coal mine work area adopting gob-side entry retaining method exploitation.
Background technology
In order to reclaim the safety pillar staying in traditional mining mode mode and establish, adopt certain technological means the tunnel of a upper section again supporting to be left for next section to use, this way in lane of staying is called gob side entry retaining, do like this and can retain former tunnel and again utilize, be conducive to reasonable development coal resources, improve coal recovery rate, fundamentally improve the nervous situation that coal mine excavation is taken over.Domestic main employing concrete filling body of wall at present, but concrete filling materials for wall consumption is large, complex process, speed of application are slow, engineering cost is high, and therefore a kind of simple, safe and reliable obturation needs the production problem of solution at present badly.
Summary of the invention
Technical problem: the purpose of this utility model is the deficiency overcome in prior art, by changing material and the structure of traditional obturation, propose and a kind of simple, efficient, safe and reliablely anti-ly break type gob side entry retaining filling air bag, be used for replacing existing filled wall bodies of gob-side retained entries.
Technical scheme: the utility model ` mono-kind is anti-breaks type gob side entry retaining filling air bag, comprises the diamond mesh covered outside cuboid flexible rubber air bag and cuboid flexible rubber air bag.Diamond mesh is covered in the outside of cuboid flexible rubber air bag uniformly.Diamond mesh is woven by steel wire or iron wire to form.Flexible rubber air bag height is identical with working face mining height, and width is 1-5 rice, and length is 1-10 rice.
Beneficial effect:
1. can prevent spoil scratch cuboid flexible rubber air bag, safe and reliable;
2.structure is simple, simplifies construction technology, saves filler, decreases the filling procedure time used, reduce labor strength, and save the mine supplement production links such as the transport of material;
3.during filling, cuboid flexible rubber air bag is easy to connect top, can close the goaf in time.
Accompanying drawing explanation
Fig. 1 is plane figure of the present utility model;
1-diamond mesh in figure, 2-cuboid flexible rubber air bag, 3-stays lane, 4-goaf, 5-coal-face, 6-coal.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the utility model will be further described:
The utility model one is anti-as shown in Figure 1 breaks type gob side entry retaining filling air bag, and comprise diamond mesh (1), cuboid flexible rubber air bag (2), diamond mesh (1) is covered in the outside of cuboid flexible rubber air bag (2) uniformly.Diamond mesh (1) is woven by steel wire or iron wire to form.Flexible rubber air bag height (2) is identical with mining height, and width is 1-5 rice, and length is 1-10 rice.A kind of anti-using method breaking type gob side entry retaining filling air bag of the utility model: after working face extraction, on the edge at coal-face (5) rear, the height cuboid flexible rubber air bag (2) identical with coal-face height is laid near goaf (4) side in the empty tunnel (3) that retains, inflation, make cuboid flexible rubber air bag (2) fully connect top and reach intended support power, along with constantly pushing ahead of coal-face (5), often push ahead a step pitch, complete the layout of a cuboid flexible rubber air bag (2), wholely stay lane until complete.
Claims (1)
1. prevent breaking type gob side entry retaining filling air bag for one kind, it is characterized in that: it is made up of diamond mesh (1) and cuboid flexible rubber air bag (2), diamond mesh (1) is overlying on the outside of cuboid flexible rubber air bag (2) uniformly, diamond mesh (1) is woven by steel wire or iron wire to form, flexible rubber air bag height is identical with working face mining height, width is 1-5 rice, and length is 1-10 rice.
