Study Of Gas Geology And Gas Forecast In Zhaozhuang Mine

Gas is the gas geological-mass of geological formation, geological evolution control the formation conditions, storage conditions, occurrence and distribution law of gas.Now the occurrence of coal gas is the result of coal-bearing strata sufferring complex geological history evolution interactionTo the 3 # coal seam of Zhaozhuang mine for Jincheng Anthracite Mining Group the study , the paper researchs the controlaction on coal gas for different geological structureuse using tectonics theory about plate, the regional geological evolution theory and sequential control theory on gas occurrence; It analyzes gas occurrence characteristics and tectonic coal developmental characteristics of zhaozhuang mine through the statistics of a large number of field measurement of gas emission and gas content data, and field observations of tectonic coal distribution and combination of geological evolution, and studies the controlaction on coal gas for different structures Zhaozhuang mine is located in the middle east of the Qinshui Basin, watershed area of the Haihe River ZhuozhangHe basin and Yellow River Dan River basin, watershed throughout the mine, its hydrogeological conditions is very special. The paper uses three function forms: water transport dispersion effect, the role of hydraulic closed, hydraulic sealing effect , to analyze the hydrogeological conditions how to impact the occurrence of coal seam gas. Finally, using linear regression to predict gas flow-volume and gas content of 3 # coal seam.
