摘　　要：为减少巴拉素煤矿副井马头门涌水量并保障马头门巷道安全掘进,对巴拉素煤矿副井马头门涌水情况进行了现场监测。结合巴拉素煤矿地质条件,针对矿建期间含水煤层条件下的马头门涌水情况,提出了“引流注浆,帷幕封堵”的注浆堵水方案,并将其应用于副井井筒的水害治理。实践表明,该方法成功在待掘马头门巷道周围形成了止水帷幕,井筒马头门涌水量减少至11 m^3/h,达到注浆堵水目标,保障了马头门巷道的安全顺利掘进,可为类似地质条件煤矿矿井建设期间的水害治理提供实践借鉴。In order to reduce the water inflow of auxiliary shaft and ensure the safety excavation of ingate roadway in Balasu Coal Mine,the water inflow from the ingate was monitored on site.Based on the mine geological conditions and the water inflow in ingate,the grouting and water shutoff scheme of“drainage grouting,curtain sealing”was proposed.Through the water hazard control of auxiliary shaft,the water inflow of ingate of auxiliary shaft was reduced to 11 m ^3/h,which achieves the goal of grouting and water shutoff,and ensures the safe and smooth driving of ingate roadway.The practice can provide reference for water hazard control during the construction of coal mines with similar geological conditions.
