摘　　要：某矿采用分矿房、矿柱两步骤回采的大直径深孔阶段空场嗣后充填采矿法,充填材料为分级尾砂胶结充填料。因采空区内含有渗水,且水质呈现酸性,为探究在酸性环境下不同时间段充填料的凝固效果及稳定性能,进行了充填材料耐酸性试验,并分别与固化剂、混凝土等材料进行耐酸性对比。A mine adopts the large-diameter and long-hole stage open-stope subsequent filling mining method with two steps of mining room and pillar,and the filling material is graded tailings cemented filling material.Because there is water seepage in the goaf,and the water quality is acidic,in order to explore the solidification effect and stability performance of filling fillers in different time periods under acidic environment,acid resistance test of filling materials was carried out,and acid resistance was compared with curing agent,concrete and other materials.
