摘要
针对织金新华磷矿区果化矿段矿体赋存条件,研究选取不切顶盘区房柱法回采,探讨了缓倾斜中厚矿体的采场参数,通过对回采顺序、采准切割、回采工艺及顶板管理的研究,达到安全、高效、低成本回采要求,为合理开发织金新华磷矿区资源提供了技术参考。
According to the occurrence condition of orebody a Guohua section in Zhijin-Xinhua phosphate mine,through studying,uncovered top panel room-pillar method was selected to mine it.The structural parameters of stope for gently inclined and medium thick orebody were discussed.The stoping sequence,preparatory and cut-off workings,stoping technique and roo management were studied,so as to meet the requirements of safety and high efficiency mining with lower cost of production,also provide technical reference for developing the resources in Zhijin-Xinhua phosphate mine.
