桂花矿床菱形斜坡道采准高效采矿法的探讨

Discussion on High Efficiency Mining Method of Diamond Ramp Mining Preparation in Guihua Deposit

桂花矿床矿体仅为平均厚度0.59 m,平均倾角25°的极薄缓倾斜矿体。由于这种矿体赋存开采条件的特殊性,矿山的开采长期处于民采开发。本文提出解决的问题其实质就是直苴分公司中段运输无轨开拓方式下的无轨运输设备如何直接进入采区采场作业面来提高采矿生产效率、效益的问题。

The average thickness of Guihua deposit is 0. 59 m, it is a gentle dip and extra-narrow ore body of 25° obliquity, due to special mining condition exists in this ore body, the ore mining were in a state of disorder mining. The problem should be solved in this paper is： how the trackless haulage plant in the sublevel of Zhiju branch company directly enter into the work surface of mining area, so as to improve the production efficiency and production benefit.
