Abstract:Based on comprehensive geophysical exploration technology,which uses 3D seismic and transient electromagnetic methods to comprehensively detect the water accumulation in goaf of Dangshuigou Coal Mine.Elaborated on the working principles and implementa-tion processes of 3D seismic and transient electromagnetic methods,the working principles of comprehensive geophysical methods were determined,and 3D seismic method was uesd to determine that the goaf area of No.4201,No.9201,and No.9203 working faces did not change and the attribute values were normal;the goaf area in No.4 coal seam of Shangmashi was reduced and its attribute values were normal.The area of No.9 goaf in Shangmashi has increased,with abnormal attribute values.A new goaf in Quan'an Xiaoyao has been added,with abnormal attribute values.Further detailed measurements were conducted using transient electromagnetic method to deter-mine three small kiln mining areas.There are 6 locations in goaf water accumulation area,including 2 locations in No.4 coal seam with a total area of 225 543 m2,and 4 locations in No.9 coal seam with a total area of 41 075 m2;there are 3 locations in goaf area,including 1 location in No.4 coal seam with a total area of 35 918 m2,and 2 locations in No.9 coal seam with a total area of 90 422 m2.The rele-vant conclusions can provide a basis for the treatment of water accumulation in the mine goaf.
