摘要
据尖山铁矿破碎机硐室的围岩稳定性监测数据 ,采用适宜的理论及经验公式 ,利用简化的几何及力学模型 ,进行硐室围岩物理力学参数的反分析计算。据此 ,得出围岩的应力分布规律 ,进行围岩稳定性分析。
Using suitable theory,empirical formula,simplified geometric and mechanical models,backward analysis calculation of physical and mechanical indexes of surrounding rock of cave is conducted based on monitoring data of surrounding rock stability of crusher cave in Jianshan Iron Ore Mine.The stress distribution rule of surrounding rock is obtained and surrounding rock stability is analyzed.
