In order to effectively prevent coal mine gas overrun accidents and realize mine safety production, this paper establishes an emergency response mode for coal mine gas overrun based on the principle of feedback control. Secondly, on this basis, applying the theory of "system algebraic state equation" and using MATLAB as the technical means to obtain the mathematical expression of the response, the mathematical model of the emergency response of coal mine gas exceeding the limit was established. Thirdly, use Origin software to draw the transition response curve when the expression takes different parameters. The results show that the operation results of the established mathematical model of coal mine gas overrun emergency response are consistent with the actual response process conditions, verifying the mathematical model built The correctness of this method provides a new working idea for coal mine gas overrun control.
