屯兰矿各组煤合理配采方案的研究

Study on Coordinated Mining Plans of 2#、8#、9# Coal in Tunlan Coal Mine

通过对屯兰矿可采煤层 2 # 、8# 、9# 煤进行合理回收与配采方案的研究。得出结论 :2 #与 8#煤以 1 .0 5∶ 1配采比较合理 ,8#煤与 9#煤不适合配采 ,9#煤适合单独采。这样 ,既合理利用屯兰矿井下煤炭资源 ,又提高了精煤产率 ,满足市场需求 。

Shudies rational recycle and coordinated mining for 2 # 、8#、9# coal in Tunlan coal mine,reaches a conclusion that to coordinate mi ning 2# and8#coal is more rational with the ration of 1.05∶1,8#cial and 9#coal is not suited coodinated mining,9#coal is suited alone mining so both the coal resoures in Tunlan coal mine is raised,it meets the demands of market and ensures continued development of Tunlan coal mine.
