贵州遵义锰矿急倾斜矿体采矿方法的应用

The Application of Inclined Orebody Mining Method in Zhunyi Manganese Mine

遵义锰矿西部倾斜矿体采用敞开式漏斗留矿采矿法，基本解决了多年来存在的采矿方法问题，特别是从技术角度解决了出矿期间人员进入采场的安全问题。采场的应用表明该法主要技术指标合理，可在该矿下中段急倾斜矿块推广使用，亦可在其它同类型矿山使用。

The shrinkage mining method by open type hopper is adopted for inclined orebody at the west of Zunyi Manganese Mine. It solves the problem in the mining method, especially overcomes, from the angle of technology, the safety problem of worker, when entering stope during the period of mining. The application to the stope shows that this method, with the main technical index being reasonable, can be widely applied to the middle and lower section of inclined orebody in this mine, and also can be utilized in other same kind of mines.
