There are many factors that affect the gas concentration in the fully mechanized coal mining face, and only by making clear the internal relations among various factors can we better predict the underground safety production situation. In view of the characteristics that GRA can be used for statistical analysis between multiple dependent variables and multiple independent variables, based on the basic principle of gray correlation analysis, a group sequence gray correlation analysis method suitable for the statistical analysis of gas concentration in fully mechanized coal mining faces is established. First, analyze and select the influencing factors of the gas concentration in the fully mechanized mining face, and then use the gray correlation analysis method to verify the influencing factors. Finally, select the gas concentration in the inlet air flow, the gas concentration in the upper corner, the gas concentration in the return air flow, the gas emission, the wind speed, the coal cutting speed of the shearer, and the atmospheric pressure to form the gas concentration influencing factor system.
