复杂条件下安全贯通老巷的方法

New method of Safely Roadway Threaded Together under Complicated Conditions

复杂条件下贯通老巷,容易造成采空区瓦斯突然涌出,更容易造成遗落的煤炭自燃,通过采取新方法,有效预防采空区煤炭自燃,保证矿井的安全生产。

Roadway threaded together under complex conditions is likely to cause sudden gas gushing in the goaf and more likely to cause spontaneous combustion of the lost coal.By adopting new methods,the spontaneous combustion of coal in the goaf can be effectively prevented to ensure the safe production of the mine.
