摘　　要：针对甘冲石灰石矿在开采过程中遇到的矿区南部顶板岩石剥离量大和北部孤立山头开拓难度大等不利因素,通过分析计算和优化,对矿区南部顶板岩石采取配矿措施,北部孤立山头采用高台阶开采的方法,有效减少了不利客观条件对开采的影响,取得了一定的经济效益。The trip amounts of roof rock in the south of Ganchong limestone are big, and the isolated mountain tops in the north are hard to exploit, there are two disadvantageous objective conditions in the mining process in Ganchong limestone. Through analysis calculating and optimization, we take ore matching measure toward the roof rock in the south of limestone, and take high step mining process to exploit the isolated mountain top in the north mining. The measures that we take can decrease the effect of disadvantage object conditions in the mining process effectively, and produce some economic benefits.
