摘　　要：针对近期嗣后法采场中深孔施工问题,经常发生中深孔未达到设计深度而出现透孔或打入松散体的现象,从而导致钻孔变形、塌孔,直接影响了后期爆破效果。根据目前嗣后法区域矿岩性质并结合当前的采矿工艺,提出了加快膏体充填速度,控制拉底爆破出矿量等一系列安全措施,以保证采区安全高效进行回采。Some problems existing in medium-length hole drilling, such as drilling into loose body or through hole when it can not reach the design depth, caused the borehole deformation and collapse, and it directly influenced the blasting effect. Combining current mining method with nrebody properties, some measures of speeding up paste backfilling, controlling ore yieht of toe hlasting were put forward, which guaranteed the sate and effective mining.
