Study On The Law Of Gas-geology And Gas Prediction In Xiadian Coalmine

The gas is a product of geological processes, gas generation, preservation, occurrence and distribution are controlled by geological evolution. It has been proved that gas-geology research is the basis of how to solve the gas disaster.This paper using plate tectonic theory, regional geological evolution and gas occurrence tectonic cascade control theory, studies the mining area, LuAn mine geological structures of gas occurrence of control; Combined with a XiaDian geological data and coal gas, preparation of measured data of mine gas geology map, Research mine gas mineralizing rules.Through compileding mine gas geology map of XiaDian, studies the fault, drape, coal buried depth, roof and floor lithology, the coal thickness, coal to gas occurrence of volatile matter the influence of multiple linear regression analysis, using the multiple linear regression analysis method, Established the mathematical model, drawing the gas content isoline; Respectively with gas geology statistics and prediction of sub-gas source to predict the absolute gas emission in XiaDian coal, drawing the absolute gas flow-volume isoline; It calculating the methane resource in coal-bed, and identifying it as the lower resource abundance.Preliminary forecast for coal and gas outburst danger zone.
