急倾斜脉状矿体采矿量计算方法分析

Ore yield calculation method analysis in steeply-inclined vein orebody mining

针对地下矿山急倾斜脉状矿体开采过程中出现的采场实际采出矿石量计算错误等一系列问题,运用科学的研究方法和技术,深入系统地推导出了该类采场实际采出矿石量的计算公式,分析了垂直素描法在急倾斜脉状矿体采场测量素描中的实用性,验证了采场合格采幅是垂直采宽而并非水平采宽。这些研究成果有效解决了急倾斜脉状矿体采矿量计算问题,对优化矿山企业生产技术管理具有一定的意义和价值。

According to the problems of real ore yield calculation mistake in underground steeply-inclined vein orebody mining,using scientific research method and techniques,the real ore yield calculation formula was systemically conducted.The practicability of vertical sketch method in the survey and sketch of steeply-inclined vein orebody stope was analyzed.It is verified that the stope qualified mining width is vertical mining width but not level mining width.These research results resolved the ore yield calculation problem effectively in steeply-inclined vein orebody mining,and it has significance and value for optimizing the management of production technology.
