长壁式陷落采矿法生产准备矿量的管理

The Management of Production Preparation Ore Quantity of Longwall Caving Ore Method

王村铝土矿采用长壁式陷落法采矿，生产准备矿量的计算为开拓矿量由采区放矿轮子坡担负矿量确定；采准、回采矿量以矿块一年和半年的生产量计算。同时加强管理，做好边角矿的准备，使生产准备矿量及其保有时间较实际地反映了矿量的贮存量，满足了生产需要。

The ore mining of Wangcun Alumina Mine is used of longwall caving ore method.The calculation of production preparation ore quantity is following:developing ore quantity is decided by loading ore quantity of draw wheel slopes and mining preparation,stoping ore quantity are calculated by ore block productive capacity of one year and half year.Through strengthening management and to do excellent preparation for edge ore,the production preparation ore quantity and its maintaining time can reflect actually the reserves of ore and it can meet the requirements of production.
