摘要
针对杨庄煤矿拟开采区域3642工作面的复杂地质条件,采用巷道充填开采方法,将附近岩巷掘进所产生的矸石充填到煤层巷道中,利用矸石置换出煤炭资源,从而达到既开采出煤炭资源,又实现综合治理煤矿矸石的双重目的。
According to the complicated geological conditions of Yangzhuang coal mine quasi mining 3642 working face, this paper used alley backfill mining method, made the gangue caused near rock roadway excavation fill to the coal alley, utilization of gangue replacement of coal resources, so as to achieve not only mine coal resources, but also realize the dual purpose of comprehensive management of coal gangue.
