霍宝干河煤矿综采面回采巷道支护技术研究

HuoBaoGan river coal mining roadway supporting technology research

针对目前巷道支护存在的问题,结合霍宝干河煤矿2-118B工作面工程背景,对其巷支护及工作面两巷超前支护进行了详细的设计,同时对其单体柱选型以及支护强度进行了计算。另外针对各种工况情况,对其工作面顶板支护提出了详细的方案设计。在实际应用中很好的解决了现场支护问题,并取得了良好的支护效果,这对其他类似井田巷道支护方案的选择具有借鉴及理论指导作用。

in view of the present problems of roadway support, 2-118 - b HuoBaoGan river coal mine working face engineering background,the roadway supporting and working face two lane forepole has carried on the detailed design, at the same time the single column selection aswell as the supporting intensity were calculated. Under various working conditions in addition to the circumstances, the working face roofsupport detailed scheme design are put forward. In practical application is very good to solve the problem on site support, and achieved goodsupporting effect, the choice of other similar mine roadway support scheme has a reference and theoretical guidance.
