薄煤层工作面过复杂地质构造技术方案研究

Study on the Technical Scheme of Complicated Geological Structure in the Thin Coal Seam Face

针对同煤集团云冈矿薄煤层工作面出现陷落柱群及大落差断层群复杂构造问题,分别从合理控制采高、合理调整采煤工艺、优化过陷落柱及断层方法及顶板管理方面提出最优方案。通过现场实测效果分析可知,该方案具有合理性和可行性,并为该矿取得了良好的经济效益,具有较为广泛的推广应用价值。

According to the complex structure problem of collapse column group and large gap fault group in the thin coal seam face of Yungang Coal Mine in Datong Coal Mine Group, the paper respectively puts forward the optimal scheme from the reasonable control of the mining height, the rational adjustment of the coal mining technology, optimized methods of collapse column and fault, and roof control through the analysis of the field test results, which showed that the scheme is reasonable and feasible, has a good economic benefit for the mine, and has a wide range of application value.
