Abstract: To counter the fact that the measured gas content parameters are less and the proportion of the developed area is small to the mine area in Mulan Coal Mine, study was carried out in this paper on the multi-source parameter acquisition method for gas content in this mine, about 123 sets of gas content data covering a range from 200 m to 500 m of the whole mine were obtained. The data sources mainly included the introduction of a new technology for continuous linear or planar gas content measurement, the gas content parameters obtained by the inversion of the routine prediction indicators of coal and gas outburst, the actually measured gas content parameters, the dynamic calibration gas content parameter obtained by geological boreholes, and the gas content parameters obtained by the back-calculation of gas emission amount in the working face.The gas data obtained by various methods can cover the whole area of the mine and better reflect the distribution of the mine gas disasters.
