Abstract: The paper introduced a design scheme of gas geological map management information system of coal mine based on MapInfo and secondary development control object MapX4.5 of GIS application software system taking informatization construction of Xindeng Coal Mine as an example. It analyzed working flow of constructing information database of gas geological map, and detailedly introduced modules design of layer management, data coding, information display of thematic map, artificial neural network analysis of gas outburst area, fault tree analysis of gas outburst and trend surface analysis of gas and geology variables of the system. The actual application showed that the system can effectively analyze gas geological regulation numerically and visually according to gas geological information of coal mine.
