Mathematical Model of Coal Mine Gas and Coal Dust Control

Abstract

The best is to read these instructions and follow the outline of this text. The coal mine production safety is one of China's current problems to be solved, do a good job monitoring and control of underground gas and coal dust is a key link to achieve safety in production. In this paper, the programming model is used to find the best ventilation rate and then control the mine gas and coal dust concentration effectively. Based on “Coal Mine Safety Regulations” and characteristics of coal dust and gas explosion with the relationship of mutual influence, we come to the possibility of coal mine explosion hazard. Finally, with the linear regression knowledge, we figure out the relationship between the wind speed and concentration of gas and coal dust, then we express the gas density and dust concentration in different parts of the mine by air volume function, through the limit of safe production on the gas concentration and coal dust concentration, to find constraints on air volume, construct a linear programming model, finally get optimum ventilation rate and the optimal control method.
