中关铁矿嗣后充填体强度优化及地表沉降研究

Study on Strength Optimization and Surface Settlement of Subsequent Filling in Zhongguan Iron Mine

中关铁矿地质条件复杂,富水性强,围岩的稳定性差。在实际生产中,合理确定开采结构参数、设定充填体性能指标,研究分析围岩及充填体的力学作用机理是解决矿体难采、减小地表沉降的技术关键。

The geological conditions of Zhongguan Iron Mine are complex,water-rich,and the stability of most surrounding rocks is poor.In actual production,it is the key to solve the complex and difficult mining and reduce the surface subsidence of Zhongguan Iron Mine successfully to reasonably determine the mining structure parameters,set the performance index of filling body,and study and analyze the mechanics mechanism of surrounding rock and filling body.
