Gas transfer law in closed fire zone of a coal mine;
矿井封闭火区内气体运移规律
It is one of methods to prevent coal mine fire with inert gas,however,it has induced gas explosion when the inert gas was injected into closed fire zone.
注惰是矿井火灾救灾措施之一,但在救灾实践中向封闭火区注惰却诱发了爆炸,因此研究注惰对封闭火区可燃气体运移规律的影响十分必要。
This paper analysizes the reason of coal well explosion,calculates the explosive limitiation of flammable gas,analysizes explosive fatalness after fire zone close down、Sorts of control technology of explosion and blunt are studied.
