摘要
针对特厚煤层综放工作面停采期间遇顶板破碎支护困难的情况,基于钻孔窥视仪对顶板完整性的观测数据,通过优化停采距离、固化顶板及煤壁、优化支护工艺和使用短割短支等方法,取得了良好的顶板治理效果,实现了工作面的安全停采。
Based on the observation data of drilling peeper on the top plate integrity,the methods of stopping the mining distance,curing the top plate and coal wall,optimizing the supporting technology and using the short cutting and short branch are used.A good effect of roof management has been achieved,and the safety of the working face has been stopped.
