摘要
某铁矿山采用房柱法开采,矿房采用浅孔分段空场嗣后(废石)充填采矿法回采,回采已经接近尾声。结合该矿矿柱的实际情况,提出了采用留设矿壁的上向水平分层进路充填采矿法来回收废石充填体之间的间柱,采取安全管理措施,实现了间柱的安全回采,取得了较好的经济效益和社会效益。
A mine adopted the room and pillar mining method,mine room with a shallow hole segmented the stope subsequent（waste rock） filling mining method and its production is in closing.Combined with the present situation,the upward layer filling method with reservation ore wall is proposed.The pillar between waste backfill was recycled by this method.The measures of safety management were adopted,and good economic and social benefits have been produced.
