摘要
在分析已有地测数据的基础上,采用RQD法、RMR法、Q法、MRMR法等崩性评价方法,对某矿区矿岩的可崩性进行了分析评价,确定了某矿区的可崩性等级。应用的BCF块度分析预测系统对某矿区矿岩的崩落块度进行了分析预测,为底部结构设计提供了依据。
Based on the data of geotechnical survey,the cavability of ore/rock in some mining area was analyzed and evaluated with RQD method,RMR method,Q-system and MRMR method,and the levels of cavability of ore/rock masses were determined.The size distribution of caved fragments was analyzed and predicted with BCF,a program to predict block cave fragmentation,it provided a basis for the design of bottom structure of block caving.
