房柱法为兴隆磷矿现使用的采矿方法，该采矿方法在回采过程中需要留设大量的矿柱，导致矿石回收率低，而且后期采空区处理工程复杂、安全管理压力大。结合矿山开采技术条件及矿山现状，研究采用矿房、矿柱两步回采嗣后充填采矿法进行回采。浅孔落矿，二步骤回采，先采矿柱，采用高强度胶结充填；后采矿房，矿房采用尾砂非胶结或者废石充填，无大面积采空区暴露。该采矿方法有利于矿山地压管理，同时可提高矿石资源的回收率，减少尾砂废石排放对地表环境产生的污染，改善矿区环境的同时减轻拦渣坝防洪压力。

Room and pillar mining method is being used by Xinglong phosphate mine ,w hich needs a large number of pillars in mining process .It led to low recovery rate of ore ,and disposal goaf engineering complexly .Safety management is more stressful .The combination of present situation and mining conditions ,research use the room and pillar subsequent filling method in two steps ,Shallow blasting ,two steps mining .First ,we stope pillars ,using high‐strength cement filling ;second ,stope rooms ,using non‐cemented mine tailings or waste rock filling ,there is no large goaf exposed .This mining method is good to increase the recovery rate of ore resources ;at the same time ,reduce tailings waste pollution caused by emissions on the earth′s surface environment ,w hile ,improve the environment in mining area ,and reduce slag dam flood control pressure to stop .
