摘　　要：磨坊矿结合生产实际,设计采用分层开采的切顶房柱采矿法开采缓倾斜中厚矿体。实践证明,分层开采的切顶房柱采矿法具有损失率低、贫化率低、回采率高、工艺技术简单等优点。In Mofang mine, combining with mining practice, slice and room - and - pillar mining with overcut is applied to the mining of gently inclined medium - thick ore - body. The practice has shown that this method has many advantages such as low Mining loss rate and ore dilution rate ,high ore recovery rate, and simple technique, so mining cost ＇can be decreased greatly.
