摘要
本文以中兴煤矿1215_下运巷掘进为背景,通过分析1215_下运巷的巷道变形原因,结合让压支护机理,确定了1215_下运巷让压支护施工工艺,经效果验证该技术可满足巷道稳定控制的要求。
Based on the background of ZTE coal mine 1215 transport roadway, by analyzing the reason of transport roadway deformation, combined with the yielding mechanism, determine the 1215 transport roadway yielding supporting construction technology, the result showed that the support effect can meet the requirements of roadway stability control.
