环状隔离体技术在塔然高勒煤矿主井冻结孔涌水封堵中的应用

摘要

分析了塔然高勒煤矿主井井筒涌水特征及水文地质条件，揭示了井筒冻结孔水害机理，提出利用环状隔离体技术治理水害，即在井筒隔水层中沿冻结圈施工小断面环形巷道，揭露、截断冻结管，并对环形巷道回填混凝土，形成环状隔离体，彻底隔断环状导水通道，根治水害。应用表明，该技术治理井筒冻结孔水害具有经济合理、质量可靠、工期较短的优势，可为同类矿山水害治理提供参考。%The water inflow characteristics and hydrogeology condition of the main shaft in Taran-gaole coal mine are analyzed in detail,the mechanism of water disaster of freezing shaft hole is revealed. The annular isolation technology is used to deal with the water disaster in the main shaft in Tarangaole coal mine,to be specific,a small section annular tunnel along the frozen circle in the shaft water-resisting layer is constructed to expose and cut off the freezing tube,an annular isolated body is formed by backfill-ing concrete for annular tunnel to separate the annular conductor completely to solving the water disaster of the main shaft in Tarangaole coal mine thoroughly.The application results show that the annular isola-tion technology with the characteristics of economic and reasonable,reliable quality and short construction period,besides that,it can provide reference for the similar mines.
