摘要
根据金川集团公司Ⅲ矿区的工程地质条件，采用Q、MRMR等多种岩体质量分级方法，对矿体和主要围岩的可崩性进行了分析评价，结果表明：金川Ⅲ矿区的超基性岩为中等易崩，大理岩和矿体为中等易崩-易崩，混合岩的可崩性最好，为极易崩～易崩。研究结果为Ⅲ矿区自然崩落采矿法的设计、生产提供了依据。
According to the engineering geological conditions of Ⅲ mining area of Jinchuan Group Ltd, some rock mass quality classification methods such as Q system, MRMR and so on were used to analysis the cavability of ore body and surrounding rock. The results indicated that the cavability of Ultramafic rock is moderate, the cavability of marble and ore body is moderate to well, migmatite is extremely easy to cave in the mining area. These researched results has provided the basis for the design of block caving system and the production in Ⅲ mining area of Jinchuan Group Ltd.
