平朔矿区露井联采下端帮治理措施研究

Study on Control Measures of End Slope Under Surface and Underground Combined Mining in Pingshuo Mining Area

文章分析了露井联采下端帮稳定性影响因素,在此基础上结合平朔矿区露井联采的实例,采用Geo-slope数值模拟软件对平朔露井联采区域的端帮稳定性进行计算,根据计算结果给出了相关治理建议及措施,主要是露天与井工的时空关系处理以及露井联采下的井工工作面合理地布置方式。

The paper analyzed a stability influence factors of an end slope under a surface and underground combined mining. Based on the circumstances and in combined with the cases of the surface and underground combined mining in Pingshuo Mining Area,a Geo-slope numerical simulation software was applied to the calculation on the end slope stability in Pingshuo surface and underground combined mining area. According to the calculation results, relevant control proposals and measures were provided,would be a control of a time-space relationship between the surface mine and underground mine mainly and would be the rational layout method of the coal mining face in the underground mine under the surface mining and underground combined mining.
