摘要
侯庄分矿结合生产实践 ,设计采用预切顶房柱法开采缓倾斜中厚矿体。实践证明 ,预切顶房柱法具有采掘比小、贫化率低、回采高、工艺简单等优点 。
Combining with the production practice of Houzhuang mine, the pre truncating crest room and pillar method is designed and adopted to mine the gently dipping middle thick ore body. The practice has identified that pre truncating crest room and pillar method has features of small rate of excavation and recovering, low depletion rate, high percentage extraction, and simple technique etc. The method has decreased the mining cost greatly.
