【摘要】：基于林南倉礦-650 m石門井下超前探鉆孔發(fā)生噴孔現(xiàn)象和圍巖泥化流變巷道垮塌事故,研究了復(fù)雜條件下超前探查和綜合防治水技術(shù)路線,介紹了防治水工程實施情況。實踐表明,井上與井下防治水工程相結(jié)合以及物探與鉆探相結(jié)合、疏水與堵水相結(jié)合、超前探測與綜合治理相結(jié)合的"四位一體"綜合防治水技術(shù)效果顯著,有效解決了影響工程施工的安全技術(shù)難題。
[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.
