Abstract：In order to clarify the hydraulic connection between the underground coal seam stratum and the aquifer of the coal mine,Ningzheng mining area in Qingyang,Gansu province is taken as an example,the average buried depth of the floor of the main coal seam is between 700 and 1000 m,the roof Luohe Formation is the main aquifer,and the development degree of geological structure is medium.On the basis of the analysis and study of coal mine geological and physical characteristics,anti magnetic flux transient electromagnetic exploration method is used instead of conventional transient electromagnetic method,to infer the fault or the geological boundary structure,judge the hydraulic connection between them,finally delineate between the coal strata and Luohe Aquifer containing(guide)water channel,and verify its effectiveness through drilling.
