摘要
根据某磷矿的开采技术条件,结合矿山实际情况采用"同步形成间隔矿柱中深孔房柱法配合条带式矿柱浅孔房柱法"开采缓倾斜中厚两层矿矿体,为缓倾斜中厚两层矿矿体的开采方式提供了新思路。
In accordance with the technical conditions available in a phosphate orebody,combined with its practical situations,two-layered orebody of gentle incline and moderate thickness is exploited by medium-length bore hole pillar-and-room method with synchronously formed barrier pillar and strip pillar shallow bore hole room-and-pillar method,which will provide a new way of exploiting the f two-layered orebody of gentle incline and moderate thickness.
