摘要
呼和乌素煤矿露天采坑因与小煤窑采空区贯通导致突水被淹,进而波及呼和乌素井工矿和临近补连塔煤矿采空区,基于此,研究采取了封堵突水点、注浆封堵突水巷道、积极排水、可控疏水降压等措施,并提出了永久解决乌兰木伦河对相关矿井影响的应对方案,保证了矿井的安全。
As Hoh Us open pit coal mine cut- through the goaf of a small mine,water inrush accident happened,and spread to Hoh Us underground mine and the adjacent goaf of Bulianta coal mine.Based on this condition,water inrush point was blocked,water inrush roadway was sealed with grouting,water drainage and controllable water pumping and pressure releasing were conducted,ensuring the coal mine safety.And the permanent solution for coal mine water problems caused by Ulan Moron River.
