Abstract: In response to the problems of long measurement time and complex process for gas parameters in high gas and outburst mines, proposes a precise prediction and intelligent analysis method for coal seam gas parameters, and has conducted experiments in Baode Coal Mine. Firstly, the DGC automatic gas content acquisition interface and WTC-1 gas output data acquisition instrument are developed to realize automatic gas parameter acquisition. Secondly, a fusion analysis method of coal seam gas multi-source data is established to realize the mutual feed verification, automatic identification and correction of multi-channel gas data such as geological prospecting, production measurement and inversion calculation, so as to improve the reliability of basic gas data. Thirdly, the influencing factors and main controlling factors of gas occurrence in No.8 coal seam of Baode Coal Mine are analyzed, and geological units are divided. Based on this, the accurate prediction model of gas parameters in No.8 coal seam of Baode Coal Mine is established and its accuracy is verified. Finally, the dynamic analysis system of gas geology is developed to realize the information management of gas parameters, intelligent generation, dynamic correction and profile analysis of gas parameter prediction isoline and grid. The application of this technology significantly improves the accuracy of gas parameter prediction and intelligent analysis ability of Baode Coal Mine, and provides technical support for the safe and efficient mining and intelligent construction of coal mine.
