朱集西煤矿矸石井采用钻井法施工,井壁下沉后壁后充填质量至观重要,关系到井壁扶正、固井、封水,壁后充填能够确保井壁不上浮和破井壁底(锅底)后不下沉,并能有效隔断地表水直接侵入围岩,同时由于壁后充填量大,需要选择合适的充填方案确保充填质量符合设计要求,并降低成本。 Zhuji West coal mine gangue well construction by drilling method, the wall after the wall sinking back wall filling quality to the point of view, related to the wellbore righting, cementing, sealing water, wall filling to ensure that the wall does not float and broken wall (Bottom of the pan) does not submerge, and can effectively cut off the surface water directly invade surrounding rock. At the same time, due to the large amount of filling behind the wall, a suitable filling scheme needs to be selected to ensure the filling quality meets the design requirements and the cost is reduced.
