新城金矿X号矿体开采方法研究

Mining Method of X-ore Body in Xincheng Gold Mine

倾斜缓倾斜薄至中厚矿体,一直被视为难采矿体。首先由于该类矿体倾角缓,崩落矿石既不能借助自重在底部完全放出,也不利于高效自行设备的应用,因此,采切工程量和生产成本较高。其次此类矿体开采时,顶板管理困难,需预留大量永久矿柱,加大了损失并带来较多安全隐患。因此,选择合理的采矿方法是矿山生产的重要课题之一。新城金矿X号矿体为倾斜中厚破碎矿体,新城金矿X号矿体的采矿方法选择及研究能够为相似矿体矿山的采矿方法选择提供理论及实践依据。

Tilt gently inclined thin to medium thick ore body has been seen as hard-to-mine ore body. First of all, because the kind of ore body dip slow, neither the caved ore can not fall with the help of gravity to the bottom, nor it is not conducive to efficient application of their own equipment, therefore, the amount of mining engineering and production costs is higher. Second when mining, the management of roof is difficulty, and it needs to set a large number of permanent pillars, which increases losses and poses a high security risk. Therefore, choice of appropriate methods of mining is one of the important subjects of mine production, x ore body in Xingcheng Gold Mine is medium thick orebody, the research on the choice of mining method is helpful to the ore body similar mining.
