Abstract: In order to better mine gas geological information, a technology based on borehole imaging technology for gas borehole information extraction and coal seam trend surface analysis was proposed and applied in engineering. First, use the mining lateral resistivity video imaging logging tool to detect the borehole information, extract the borehole trajectory, borehole azimuth, borehole inclination and other information, determine the start and end positions of the coal seam, draw the borehole histogram, and obtain various types of information of lithology logging characteristics. Secondly, based on geological information such as borehole data and measurement data, the coal thickness contour map, seam floor contour map and mining surface residual value map are generated with the help of Surfer software to realize accurate analysis of coal seam trend surface. Finally, based on the borehole data of 191 boreholes, the migration rules and causes of boreholes are analyzed. The application results show that the migration of bedding borehole and perforation borehole presents a certain regularity, which is affected by formation factors and drilling schedule parameters.
