【摘要】 以岩体构造调查及构造面空间分布规律为基础,采用矿石预测的RMPSDOF微机系统,对影响矿石块度尺寸和形状组成的各因素:节理间距(频度),节理面持续性系数,两组节理面之夹角、地应力状态、各组优势节理面所占的百分比和完整岩石及弱面力学性质,对矿石块度的影响程度进行模拟研究。更多还原

【Abstract】 Based on the investigation of rock mass structure and the regularity of rockjoints distribution in space, the quantitative analysis of size and shape distribu-tion of ore fragments in block caving in different model parameters is workedout. In this model, the parameters which include joint frequency, continutity,rock mass properties, in situ stress, angle between two superiority joint sets andappearance frenquency of superiority joint sets are discussed. The microcomputerprogram RMPSDOF is used to predict the ore fragments in this research.更多还原
