Abstract
In order to identify the main minable coal seam goaf and its water accumulation in the exploration area and pro-vide effective hydrogeological basis for safe mining of coal mines,Yiyuan Coal Industry,based on transient electromagnetic technology combined with relevant geological data,detected the distribution range of water accumulation in the goafs of No.3 coal,No.8 coal,and No.15 coal within the mining area.Overlapping loop devices and large fixed source internal loop de-vices were used for testing,and the induced polarization method was adopted to further verify the water accumulation situa-tion in the electrical measurement area.Through the construction of water exploration and drainage boreholes,the water ac-cumulation in the overlying goaf of No.3 coal in the southern part of the mining area was released,eliminating the hidden danger of water accumulation in the overlying goaf of No.3 coal at the 150108 working face,and preventing the risk of roof collapse that may occur during future mining of the working face.This geophysical exploration work has obtained accurate hydrogeological data of the well field,providing a reliable basis for formulating and implementing effective waterproofing plans for the working face.关键词
