摘要
为防止秦能一矿主斜井刷扩施工时,围岩变形过大,降低工程造价,并辅助堵水,采用水泥-水玻璃双液浆,对主斜井进行了壁后注浆,使得破碎围岩整体稳定性得到了提高,渗漏水部位得到了有效控制,保证了刷扩施工的顺利进行,取得了预期效果。
In order to prevent an over deformation of the surrounding rock,to reduce the engineering cost and to assist the water sealing during the reaming and enlarging construction of the mine main inclined shaft in Qinneng First Mine,a cement-sodium silicate double grout was applied to the backwall grouting of the mine main inclined shaft.Thus the overall stability of the broken surrounding rock was improved and the water leakage parts were effectively controlled to ensure the remaining and enlarging construction successfully conducted.Therefore the expected effect was obtained.
