摘　　要：针对岳南煤矿整合矿井所面临的老空水潜在水害威胁与雨季水害加重等问题,为查明岳南煤矿井田中部采区3号煤层老空水的分布情况,通过研究井田地质与地球物理特征,开展了勘探区的瞬变电磁探查试验。首先以瞬变电磁法探查了3号煤层的老空水分布区域,然后再以激电测深法针对瞬变电磁法的探查结果进行验证,从而确定了岳南煤矿井田中部8处3号煤层老空水分布区,并兼顾了K5灰岩层和K2灰岩层的富水区。不仅排查了老空水这一隐蔽致灾因素,同时也为削弱雨季潜在水害威胁采取的必要防治水措施提供了依据,为煤矿下一步采掘活动奠定了技术基础。Aiming at the problems of potential water disaster threat of goaf water and aggravation of water disaster in rainy season faced by integrated mines in Yuenan Coal Mine,in order to find out the distribution of goaf water in No.3 coal seam in the central mining area of Yuenan Coal Mine,by studying the geological and geophysical characteristics of the mine field,the transient electromagnetic exploration test in the exploration area was carried out.The goaf water distribution area of No.3 coal seam was first detected by transient electromagnetic method,and then the detection results were verified by IP sounding method.The distribution area of goaf water in 8 No.3 coal seams in the middle of Yuenan Coal Mine was determined,and the water-rich area of K5 limestone and K2 limestone was taken into account.It not only investigates the hidden disaster-causing factors of goaf water,but also provides a basis for taking necessary water prevention and control measures to mitigate the potential water disaster threat in the rainy season.It also lays a technical foundation for the next mining activities of coal mine.
