| 摘 要： | 基于河南省卢氏县夜长坪钼矿自然崩落法开采优化研究成果与夜长坪矿区岩体实际情况,采用岩体地质力学分类法和可崩性指数法,对夜长坪钼矿的可崩性进行了研究与评价,结果表明,氧化矿的可崩性指数为1.94,原生矿为3.90,含矿滑石为2.82;氧化矿属于"易崩"类型,原生矿和含矿滑石为"易到中等可崩"类型,研究结论为矿山扩建提供了技术依据。

| Abstract: | According to the results of optimization research on black caving system and actual situation of rock body in Yechangping molybdenum mine,Lushi county,Henan province,the cavability of the ore/rock was investigated and estimated on the basis of geomechanics classification and cavability index.The result showed that the cavability index for the oxidized ore is 1.94,for the primary ore is 3.90 and for ore-bearing talc is 2.82,the cavability of the oxidized ore is well,and the cavability of the primary ore and ore-bearing talc is well to moderate.The studied results provide a technological basis for the enlargement of production scale in this mine. |
