摘要
据尖山铁矿破碎机硐室的围岩稳定性监测数据 ,推导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 。
By measured data of surrounding rock of crusher cave in Jianshan Iron Mine,Using suitable theoretical and practical formulas,on the basis of simplified geometry and mechanics modes,the back analysis of physics and mechanics indexes of surrounding rock was coducted,the stress distribution rule of surrounding rock was given,and stability was analyzed.
