1、【外文文献】2Coal mine mine shaft gas government technology applicationFirst, surveyEvil 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 threatenin
2、g 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 mi
3、ne 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 38, a large-scale mine pit mine shaft coal bin quantity achieved 1020, giant mine pit mine shaft coal bin quantity
4、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 th
5、e coal amount, the anthrax different may achieve 320 , 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 e
6、xplosion.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 continuo
7、usly 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 b
8、in 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 35m place gas, cannot dilute regarding the 2030m high mine shaft coal bin majority of gas, is also unable solve.Moreover t
9、he 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
10、 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 facil
11、ity 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
12、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 so
13、lve.The coal mine mine shaft coal bin gas government installment mainly aims at the solution existing coal mine mine shaft coal bin existence the gas agglomeration to exceed the allowed figure easy to create the gas explosion and the government expense expensive technology difficultySecond, mine sha
14、ft coal bin gas government installment research and designThe coal mine mine shaft coal bin gas government installment goal is the solution existing coal mine mine shaft coal bin existence gas exceeds the allowed figure easy to create the gas explosion and the government expense expensive technology
15、 difficulty, and provides one kind to be able to govern the coal mine mine shaft coal bin gas agglomeration and the elimination gas also the government expense low coal mine mine shaft coal bin gas agglomeration government installment.The coal mine mine shaft coal bin gas government installment the
16、technical plan which uses for the solution above question is: It by or a two gas separator, the gas leads the air hose, three forks a row of wind and foehn the ventilator is composed.The gas separator is located in the coal mine mine shaft coal bin coal body, three forks a row of wind to be located in above the coal bin in the air return way, foehn the ventilator is located in underneath the coal bin, leads the air hose using the gas to lead to
