Study Of Gas Occurrence Regularity And Gas Forecast In Aai Mine Area

Gas is also called the CBM, it’s a kind of more efficient clean energy than natural gas,it’s also the main threat to the coal mine safety. Using coal geology,coal seam gas geology and gas geology theory control the formation and occurrence features of coal mine gas, to study the occurrence regularity of coalbed methane resources development and mine gas disaster prevention provide a theoretical basis.Using the plate tectonics, regional geological structure evolution and gas occurrence control theory, master the geological structures in the evolution and shaping of all tectonic movements characteristic in Aai mining area. During finishing mine exploration and production in the process of determination of coal seam gas parameters, combined with the corresponding, to study the effect of geological factors on the mining of coal seam gas and distribution. According to the data, we analysis the regular of gas emission, establish the mathematical model of gas emission, provide the basis for the mine gas emission prediction of the Aai ming area.To provide the thickness of the tectonic coal, gas pressure,gas content,combined with the method of gas geology and related information,and predict the coal and gas outburst danger to the Aai mining area.On the basis of the gas occurrence regularity, according to prediction of gas content of contour by coal seam gas resources, for disaster prevention and mitigation, and provides the basis for reasonable, make full use of the gas resource.
