为了全面评价矿岩的可崩性,用于指导矿山的自然崩落采矿法设计,根据工程地质调查揭露的地质条件,考虑各种因素的相互影响,采用多因素综合评判的方法,对影响矿岩可崩性的指标进行了研究。结果表明,综合考虑岩体结构特征指标的分布规律,能更好地的反映矿岩的可崩性。结合实例,对某矿区的矿体可崩性进行了分级,得出该矿区的可崩性处于中等—较好水平,为矿山的后续工作提供了重要的指导作用。
In order to comprehensively evaluate the avalanche of ore rock and to guide the design of natural caving mining method of mine, according to the geological conditions revealed by engineering geological survey, taking into account the mutual influence of various factors, the method of multi-factor comprehensive evaluation Cogolability indicators were studied. The results show that considering the distribution of structural characteristic indexes of rock mass, the disintegrability of ore rock can be better reflected. Combining with the example, the ore body collapability of a mining area is graded, and the disintegration of the mining area is at a moderate to good level, which provides an important guiding role for the follow-up work of the mine.
