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。
Based on the research results of the optimization of the natural caving mining method of the Yechangping molybdenum deposit in Henan Province and the actual conditions of the rock mass in the Yechangping mining area, the geomechanical classification method and the disintegrability index method of the rock mass are applied to investigate the feasibility of The results show that the anodizing index of oxide ore is 1.94, the primary ore is 3.90, the ore-bearing talc is 2.82; the oxide ore belongs to the type of “easy collapse”, and the primary ore and ore-bearing talc are “Easy to moderate collapse” type, the conclusions of the study provided a technical basis for the expansion of mines.
