摘　　要：本文介绍了我国首次对坚硬裂隙矿岩体崩落性进行研究的情况。研究表明,铜矿峪矿5号矿体的崩落性属中等偏难。还介绍了一种改进的岩体崩落性分级方法。This paper introduces the study on the cavability of a hard fractured ore body. This is the first investigation on the cavability of hard fractured ore bodies in China. The study shows that the cavabilities of No.5 Ore Body at Tongkuangyu Mine are fair mainly and poor partly. A improved classification method of rock mass,cavability also is introduced in this paper.

关 键 词：坚硬裂隙岩体 崩落性 阶段自然崩落法 岩体分级
