砂岩直覆顶板预裂爆破矿压控制技术分析

在煤矿实际生产过程中,坚硬的顶板会导致采空区出现较大面积的悬顶,甚至会产生严重的漏风现象,在一定条件下还会导致采空区出现大面积垮落现象,这样就会严重威胁矿井支架以及井下作业人员的安全,对整个煤矿的安全生产构成极大的干扰,这也是当前煤矿生产作业过程中必须要尽快解决的问题之一。针对砂岩直覆顶板预裂爆破矿压控制技术进行了深入探讨,以期为日后相关工作的顺利进行提供参考。

Analysis of Mine Pressure Control Technology for Pre-splitting Blasting of Sandstone Direct Roof

In the actual production process of the coal mine,the hard roof will lead to a large area of suspended roof in the goaf,and even serious air leakage.Under certain conditions,it will also lead to a large area of collapse in the goaf,which will seriously threaten the safety of the mine support and underground workers,and constitute a great interference to the safety production of the whole coal mine.It is also one of the problems that must be solved as soon as possible in the current coal mine production process.In order to provide reference for the future related work,this paper made a deep discussion on the mine pressure control technology for pre-splitting blasting of sandstone direct roof.
