Abstract
Aim: To monitor dynamically and control precisely the gas content during coal mining operations as well as to reduce relevant accidents. Method: Using mathematical modeling to decide whether a coal mine is high-gas and to judge its safety degree, thus establishing mathematical and improvement model of the targeted coal mine. Results and conclusions: By mathematical modeling, the air volume required is obtained by calculation under the condition to ensure maximum security, solving the problem of gas monitoring and control in the coal mine to some extent.
