摘要
对于冲击地压煤矿而言,大型地质构造往往对冲击地压的发生起明显促进作用,甚至起主导作用。研究大型构造影响区掘进巷道的冲击地压防治技术,对冲击地压煤矿具有重要意义。本文结合陕西彬长矿区孟村煤矿,对中央一号辅运大巷穿越DF29断层期间的防冲方案进行不断的探讨和优化,实施“强支护、强卸压”,使该巷道顺利穿越了断层,为冲击地压煤矿在大型构造影响区掘进期间的防冲工作提供了参考。
For rock burst coal mines, large geological structures often play a significant role in promoting or even leading the occurrence of rock burst. It is of great significance to study the prevention and control technology of rock burst in driving roadway in large-scale tectonic influence area for rock burst coal mine. Combining with Mengcun Coal Mine in Binchang Mining Area of Shaanxi Province, this paper discusses and optimizes the scour prevention plan of No. 1 auxiliary transportation roadway of the central government during the period of crossing DF29 fault, implements "strong support and strong pressure relief", makes the roadway pass through the fault smoothly, and provides reference for scour prevention work of rock burst coal mine during excavation in large tectonic impact area.
