摘　　要：煤矿水害事故是影响煤矿安全生产与建设的重要问题,其中火烧区积水是影响煤矿安全生产的重要因素之一。由于煤矿火烧区的复杂性,其烧变范围很难确定,通过时间的积累,火烧区富水直接威胁煤矿的安全生产。通过物探方法,确定煤矿积水区的分布范围,并针对积水区进行防治水工作,是解决煤矿火烧区积水问题的主要措施。以夏阔坦煤矿为研究对象,利用瞬变电磁的“亲水性”获得视电阻率展布特征,探测出10(A1—A10)个低阻异常区,查明火烧区边界及富水性,为后续矿区安全生产提供保障。Coal mine water disaster accident is an important problem affecting coal mine safety production and construction.Among them,water accumulation in the burning area is one of the important factors affecting coal mine safety production.Because of the complexity of coal mine burning area,it is difficult to determine the burning range.Through the accumulation of time,the rich water in the burning area directly threatens the safety production of coal mine.Through geophysical prospecting methods,the distribution range of coal mine water accumulation area is determined,and water prevention and control work is carried out for the water accumulation area,which is the main measure to solve the problem of water accumulation in coal mine burning area.Taking Xiakuotan Coal Mine as an example,this study uses the"hydrophilicity"of transient electromagnetic to obtain the distribution characteristics of apparent resistivity,detects 10(A1-A10)low-resistance anomaly areas,and finds out the boundary and water-richness of the burning area,so as to provide guarantee for the safe production of the subsequent mining area.
