摘　　要：本文系统地介绍了在稳定性分析中所需岩石力学基本参数的工程处理方法和求算节理面剪切强度的一些基本公式,以及从岩石力学的观点出发.在爆破工程中选择合理的炸药—岩石匹配关系,以减小爆破虚功和提高爆破效果。This paper has systematically described the treatment methods of basic paramenters of rock mechanics used in the stability analysis.Some basic calculation formulae for shearing of the joint planes are deduced. From the viewpoint of rock mechanics, the optimal matching of explosives and rock characters has been realized in blasting operatons,resulting in the unavailable blasting power reduced and better fragmentation.
