Coal mine mine shaft gas government technology application

First, survey

Evil of the gas, shocking, gas government, imminent.

The coal mine mine shaft gas ultra limits with the gas agglomeration occurs repeatedly, even some coal mine mine shaft also has the gas explosion, is seriously threatening jobholders' safety and the coal mine safety in production.

All coal mine mine shaft all is equipped with the coal bin, the coal mine mine shaft coal bin name slides the coal shaft or “the counter-well”.The coal bin role mainly is the storage, the reprint, the cushion coal amount, is the coal mine mine shaft storage and transport coal important link, to realizes the coal output high production to play the positive role.A small mine pit mine shaft coal bin quantity is equipped with 3~8, a large-scale mine pit mine shaft coal bin quantity achieved 10~20, giant mine pit mine shaft coal bin quantity are more, therefore in the national coal mine mine pit, mine shaft coal bin quantity many may reach 1,000,000.These mine shaft coal bin in the storage, the reprint, the cushion coal amount process simultaneously is agglomerating the massive gas, in its mine shaft coal bin gas density according to the coal amount, the anthrax different may achieve 3~20 ﹪, the gas density surpasses "Coal mine safety Regulations" to stipulate greatly.The such high gas density meets friction spark, static electricity spark, stray currents, collision spark and so on kindling materials, extremely easy to cause the gas explosion.Coal mine mine shaft coal bin existence serious security hidden danger, also is the significant dangerous source, is seriously threatening jobholders' safety and the coal mine mine shaft safety in production.

Since long ago the coal mine mine shaft coal bin gas agglomeration question continuously has not obtained the very good solution significant hidden danger and the significant dangerous source, becomes the long-term puzzle coal mine safety production a big difficult problem.

In order to solve this kind of problem, the traditional solution is installs the axis in the mine shaft coal bin place above tunnel to flow the type ventilator to dilute in the coal bin the upside gas, the axis flows the type ventilator also only to be able to dilute on the coal bin the 3~5m place gas, cannot dilute regarding the 20~30m high mine shaft coal bin majority of gas, is also unable solve.Moreover the axis flows the massive gas which the type ventilator discharges in some people to work transports in the coal lane, because transports in the coal lane to have the electromechanical device and the staff, has slightly can create the gas explosion accident or the personnel carelessly suffocates the fatal accident.The axis flows the type ventilator to dilute in the coal bin the gas for to transport in the coal lane to cause the enormous harm, the dangerous harm factor still exists.

Although this to solved the mine shaft coal bin gas ultra to limit certain function, but the above equipment facility government expense was expensive, also fundamentally has not solved the hidden danger which the gas agglomeration created, still existed has the gas explosion accident hidden danger, affected the coal mine mine shaft safety in production, might say these negative measures fundamentally have not solved the gas explosion problem.

In order to solve the coal mine mine shaft coal bin gas agglomeration problem, eliminates the significant security hidden danger, eliminates the significant dangerous source, the coal profession ore advocates peace the engineers and technicians to spend and not to solve.

The coal mine mine shaft coal bin gas government installment mainly
