【摘要】：基于林南仓矿-650 m石门井下超前探钻孔发生喷孔现象和围岩泥化流变巷道垮塌事故,研究了复杂条件下超前探查和综合防治水技术路线,介绍了防治水工程实施情况。实践表明,井上与井下防治水工程相结合以及物探与钻探相结合、疏水与堵水相结合、超前探测与综合治理相结合的"四位一体"综合防治水技术效果显著,有效解决了影响工程施工的安全技术难题。
[Abstract]:Based on the phenomenon of jetting holes in -650m Shimen underground advance drilling hole and the collapse of muddy rheological roadway in surrounding rock, the technical route of advanced exploration and comprehensive water prevention under complex conditions is studied, and the implementation of water control project is introduced. The practice shows that the "four-in-one" integrated water prevention and control technology, which combines downhole and downhole water prevention engineering, geophysical exploration and drilling, hydrophobic and water shutoff, advanced detection and comprehensive treatment, has remarkable effect. The problem of safety and technology affecting engineering construction is solved effectively.
