摘　　要：提出了矿体的可崩性是自然崩落法可行性研究的重点，分析了岩体原岩应力、节理裂隙分布及其力学性质对矿体可崩性的影响，结合矿石块度预测和矿岩崩落速率预测规律。This paper points out that the cavability of orebody is the principal aspect of feasibility study of natural caving methods. The influence of in situ rock stress, joint crack distribution and mechanical properties of orebody on the cavability of orebody is analysed. Also the authors analyse the law for predicting ore lumpiness and natural caving rate of rack and key factors of designing natural caving methods for orebody mining.
