摘要:

针对新登煤矿F22-1断层突水点附近围岩破碎、隔水层薄、岩层泥化、承载能力差的特点,结合“线状”导水通道的特殊补给形式,从加固围岩和控制导水通道水压、水流两个方面,采用巷道充填、围岩加固、疏水降压、返流注浆及引流注浆等技术,解决了注浆堵水期间导水通道垮塌、隔水层承压能力差以及围岩裂隙发育的难题,成功实现了在断层破碎带注浆堵水的目的,取得了较好的效果。

Abstract:

Based on broken rock layers, thinner waterproof layers, argillation, poorer bearing capacity and special replenishment of linear water channel near the water inrush point of F22-1 fault in Xindeng Coal Mine. From the aspects of strengthening the surrounding rock and flow of the water pressure and flow of the water channel, The techniques of roadway filling, surrounding rock reinforcement, hydrophobic depressurization, returned grouting, water diversion grouting are adopted to solve the problems of water channel collapse and change, poor waterproof layers, rock fracture. The purpose of water blocking in fault fracture zone has been successfully realized.
