Abstract: In view of the large error of single geophysical parameters, the poor effect of single geophysical Prospecting method and the insufficiency of multi-solution of inversion results, a multi-parameter comprehensive geophysical Prospecting method is proposed to explore the distribution and status of No. 5-1 coal seam goaf in Zhongneng Yi'an Coal Mine in the Jurassic Coalfield of Northern Shaanxi, and the distribution and occurrence of the inner goaf of the exploration area is basically identified by geophysical verification combined with drilling exploration, which provide a reference for the disaster control of the goaf.
