Description
Technical field
The utility model is related to a kind of underground coal mine mining technique and construction safety technical field, more particularly to one kind are mining
Inflatable airbag and plugging device.
Background technology
In the back production production process of underground coal mine mining, is promoted with the back production of working face, adopt face tunnel upper corner and lean on
Nearly coal wall and goaf side, airflow velocity is low, and part is in turbulent state, it is this be vortexed the gas for making goaf gush out be difficult into
Enter into main airstream, to make high concentration gas near upper corner shuttling movement and be gathered in vortex, form corner
The gas exceeding limit at angle.Since gas is colourless, tasteless, the odorless gas released in process of coal mining, it has four
Big harm：First, can burn, cause mine fire；Second is that can explode, causes mine to ruin people and die；Third, can cause when excessive concentration
Personnel's anoxia asphyxia, even death；Fourth, coal (rock) and Gas Outburst can occur, destroys, blocks tunnel, or even personnel is caused to stop up
Breath death, gas explosion.
Therefore, during coal mine is returned and stepped on, the gas assembled in coal working face tunnel is removed in time, to ensureing operation people
The life security of member is of crucial importance.
In the prior art, it has fulfiled assignment tunnel in coal mine work area, has usually been that broken coal is loaded using woven bag mostly,
Then the mode that heap walling body is blocked avoids a large amount of gas from entering working face.But since single woven bag fills the bodily form
Shape is irregular, poor plasticity, cannot be fitted closely between each obturator, there are gap, for prevent gas from gap outward
Gush out, it is also necessary to use soft material pay the seam.But not only effect is poor, labor intensity is big, effect for the method for this kind filling working face
Rate is low, and it is higher to fill cost.
