摘要
郭屯煤矿副井井筒采用围岩、壁后、壁内综合注浆技术堵水;井底车场采用高压注浆锚杆锚注的方案治水;临时水仓采用停止掘进,设置止浆垫注浆堵水等方案。这3种治水方案取得了良好的治水效果,对深井治水具有开创性的意义。
The auxiliary shaft of Guotun coal mine adopts the comprehensive water controlling techniques of grouting surrounding rock,internal and external shaft wall rock.The shaft station employs the grouting method using high-stress grouting anchors.The temporary water sump uses the method of stopping drivage and setting grouting pad for grouting.These three grouting methods obtain positive water plugging effects,having a positive significance on water controlling of the deep shaft.
