深基岩冻结井筒封闭不良冻结孔水害治理技术

Water Disater Control Technology of Poor Sealing Frozen Hole in Deep Freezing Bedrock Shaft

  • 摘要: 为解决我国西部地区深基岩冻结井筒封闭不良冻结孔涌水水害的难题,在分析冻结孔环状导水通道生成及涌水机理的基础上,将地质分析、数值模拟、综合探测试验及实时监测等技术手段有机地结合为一体,提出一种在上覆含水层下方稳定岩层中沿冻结圈外沿掘进小断面环形截水巷道,并在截水巷道内探测、揭露冻结管进而封堵冻结孔,对截水巷回填混凝土形成一个环形隔水体,彻底隔断环状导水通道,防治深基岩冻结井筒冻结孔涌水水害新技术。应用表明,该技术相比射孔注浆治理措施节省治理费用近千万,并提前3个月投产。

     

    Abstract: In order to solve the problem of poor sealing frozen hole in- rushing water hazards of deep freezing bedrock shaft in west area of china, based on the an alysis of frozen tube annular water- transmitting channels formation and in- rushing water mechanism. Geological analysis, numerical simulation, comprehensive detecti on experimants and real- time monitoring were integrated together, provided a new technology to control deep freezing bedrock shaft frozen hole in- rushing water dam age thoroughly that drove small section annular roadway in the stability rock stratum outside the frozen wall below the upper aquifer, probed and exposed the frozen tub e and then sealed frozen hole in the annular roadway, concreted backfill in the annular roadway form an annular confining bed, cut off the annular water- transmitting ch annels thoroughly. Application results shawed that the technology saved control expenses approximately millions and millions contrast to perforation grouting, the coal mine came into service and bring about benefit ahead of schedule three months.
