The Research Of Gas Regularity And Prediction In Wulan Mine

The gas is a product of geological processes, gas generation, preservation and occurrenceare controlled by geological evolution. It has been proved that gas-geology research is thebasis of how to solve the gas disaster.This paper using plate tectonic theory, regional geological evolution and gas occurrencetectonic cascade control theory, studies the mining area, WuLan mine geological structures ofgas occurrence of control; Combined with a geological data and coal gas, preparation ofmeasured data of mine gas geology map, Research mine gas mineralizing rules.Through compileding mine gas geology map of, studies the fault, drape, coal burieddepth, roof and floor lithology and the tilt Angle of coal,to gas occurrence the influence ofmultiple linear regression analysis, using the multiple linear regression analysis method，Established the mathematical model，using stepwise regression method have the influence ofthe main controlling factors of the gas content is buried depth; Respectively with gas geologystatistics to predict the absolute gas emission in WuLan coal;It calculating the methaneresource in coal-bed.Preliminary forecast for coal. The results accord with the truth.This articleresearch conclusion to ulam ore and is near mine gas control work has guiding significance.
