摘要 矿井水害作为当前影响矿井安全作业主要灾害中的一种,由于水害所带来的矿井停产,甚至淹井事故时有发生,为提高浅埋多层采空区积水的探测能力,提出了将瞬变电磁法作为重要的水文地质勘探手段,对煤层顶板中存在的多层采空积水区范围和位置进行探查,为工作面回采期间的防治水工作提供参考资料,规避作业面回采过程中因为水害问题而出现停产等情况。结合后期的回采验证,确定这一方式为相对高效的勘查方法,对矿井的水害治理有着突出的效果。这一方法同时也对水害的预报和及时采取防护措施起到了积极作用,对类似情况下的水治理提供了重要参照。 Water damage is one of the important disasters that threaten the safety of mine production.Due to water damage,mine production is stopped,and even mine flooding accidents occur from time to time.The scope and location of the multi-layered goaf in the roof of the coal seam are explored with transient electromagnetic method as a hydrogeological exploration method,which provides reference materials for the prevention and control of water during the mining period of the working face.Accidents such as production stoppage caused by the impact of water damage on the working face is prevented during the mining period.The later mining verification shows that the method is a very effective exploration method with obvious effect on the prevention and control of mine water hazard.The method provides a reliable reference for the prediction and prevention of mine water hazards,and has a certain guiding role for the prevention and control of water under similar conditions.
