Abstract：Different coal seam pitch has a certain influence on the application of the floor water prospecting method. In this paper, test study was made on the water abundance of the floor limestone stratum of A1 coal seam according to the geological conditions of the working face of deep inclined coal seam in Huainan Coal Mining Area and by using 3D parallel electrical method, and through the data acquisition, processing and inversion in double laneways, the resistivity profile and interpretation results of the floor stratum were obtained. The site measuring results showed that under the double laneway conditions, using three-dimensional electrical method for data acquisition and processing had certain feasibility, and it can provide the basis for judging the abnormal water abundance in the floor rock stratum of the working face.
