摘　　要：针对连采面资源回收率较低的问题,结合其采空区已采支巷和煤柱相间布置的特点,发明了将开采和充填都分为两个阶段的胶结充填开采技术原理和工艺,提出了提高支巷充填接顶率的技术措施。现场工业性试验表明,充填连采面支巷开采和充填工艺实施顺利,实现了煤柱安全回收。Aiming at the problem that, the resource recovery rate of continuous mining face was low, combining with thearrangement characteristic of goal, mined branch roadway alternated with coal pillar, the principal and process ofcemented filling mining technology were proposed, in which the mining and filling were divided into two stages, thetechnical measures to improve the branch roadway roof contacted rate of filling. The industrial test showed that, theproposed process was implemented smoothly, realizing safe coal pillar recovery.
