摘　　要：区域超前探查治理技术是近几年推广的有效预防华北型煤田底板灰岩水通过垂向隐伏导水通道突水,防止淹井、淹面等水害事故的新兴技术。新集二矿受巨厚推覆体的影响,三维地震勘探及钻探无法查明地层展布、断层、陷落柱等垂向隐伏导水通道,对区域超前探查治理技术在钻探顺层跟进、隐伏构造探查设计、注浆改造工艺及治理效果评价等方面提出了新的挑战。通过工程实例对区域超前探查治理技术在推覆体下深煤层底板高承压水害防治中的应用进行研究,创新提出“施、判、探、注、评一体化”的工作思路和方法。实践表明,该方法可以有效应对巨厚推覆体影响下的煤层底板高承压奥灰含水对矿井安全开采的威胁,对类似矿区具有重要的借鉴意义。The regional advanced exploration and treatment technology is a new technology which is popularized in recent years to effectively prevent water inrush of limestone water from floor of north China coal field through vertical concealed water channel and prevent water disaster accidents such as flooded well and flooded surface.Due to the influence of huge thick nappe,the vertical concealed water channels such as stratum distribution,fault and collapse column cannot be identified by 3D seismic exploration and drilling in Xinji No.2 mine,which poses new challenges to the regional advanced exploration and treatment technology in drilling bedding follow-up,exploration design of concealed structure,grouting reconstruction technology and treatment effect evaluation.Through engineering examples,the application of regional advanced exploration and treatment technology in the prevention and control of high confined water damage in deep coal floor under nappe was studied,the working ideas and methods of application,judgment,exploration,injection and evaluation integration were put forward.Practice shows that this method can effectively deal with the threat of high pressure Ordovician ash water bearing in coal seam floor under the influence of huge thick nappe to mine safety mining,which has an important reference significance for similar mining areas.
