The Application of Math Modeling to Control the Gas Blast of Coal Mine

For gas blast accident of coal mine, the most effective preventive method is to detect and control the concentration of gas, smut and ventilation quantity. But the status in fact is very perplexing, which limits controlling the blast accident well. In this paper, the math modeling was established by using matlab program for estimating the degree of coal mine and the critical coefficient of gas blast. On the basis of this, the safety ventilation quantity was ensured. The results indicate that these models may dig up the information field well from specimen data-base files. Our algorithm can not only analyze and forecast the criticality of coal mine, but also make real-time safety inspection for gas and smut of coal mine.
