采空区积水疏放技术在煤矿中的应用

Application of Water Drainage Technology for Water Accumulation in Goaf of Coal Mines

近几年来,随着中国对能源需求量的增大,煤矿开采深度逐渐增加。但是,工作面在开采过后会形成采空区,采空区会由于地质结构等原因发生突水等状况,对于井下开采工作的顺利进行造成了一定的阻碍。对此,水治理部门的工作也面临着前所未有的压力。从安全的角度考虑,对煤矿中采空区产生积水时的两种疏放技术进行分析讨论,以期为未来煤矿开采作业提供一定的参考。

In recent years,with the increasing demand for energy in China,the depth of coal mining has been deepened.However,the mining face will form a goaf after mining,and water inrush will occur in the goaf due to geological structure and other reasons,which will hinder the smooth progress of underground mining.In this regard,the work of the water management department is also facing unprecedented pressure.From the point of view of safety,this paper analyzed and discussed two types of water drainage technology in coal mines when water accumulates in the goaf,in order to provide reference for future coal mining operations.
