Analysis on the Influence Factors of Gas Emission in Eastern 113 Working Face of Dashuitou Mine

Abstract:

There are many factors that affect the gas emission in working face. To predict and prevent this kind of gas emission, the mainly sensitive factor should be filtered and detected from many influencing factors. Taken Dashuitou Mine for an example, the main influencing factor was analyzed by using Grey correlation theory, which was atmosphere pressure. Then, the relationship between atmosphere pressure and gas emission is studied with Statistics tools. It obtained some important conclusions, include the rule of Atmospheric pressure changes in working face during a day, rule of the gas underground changes in a day, rule of correlation statistical, concrete relation between atmospheric pressure and gas emission. It would be useful on disposing of gas emission risk.
