The Gas-geology Law And Gas Forecasting In Wuyang Mine

Through the use of gas deposit step by step structure control theory ,to study the Luan Mining, Wuyang mine geological structure of the gas distribution control; Combination of a lot of gas geological data and field data in Wuyang mine, making gas geological map; to study Mine Gas deposit law, and mine gas emission and gas content prediction, evaluation coal methane (gas) resource, coal and gas outburst forecast.Main structure of Luan mining area is NNE, NE anticline and compound structure of the EW direction; the gas content is high at axis of Tianchang syncline, relatively small-scale faults and collapse column development, collapse column is distributed axis of the Tianchang synclinal about 800m range. Paper details: Making Wuyang mine gas geological map; The depth of coal seam, roof and floor rock, the distance from the fault, coal seam thickness, volatile of coal, five related factors multielement analysis shows that the multivariate analysis of gas occurrence situation is similar to the case of single factor, coal seam depth of the single factor forecast gas content; Based on the actual situation in Wuyang mine, the mine was divided into 15 block, to calculate resources; based on the measured parameters and mine geological features to predict elevation +482 seam below, near axis of Tianchang syncline, coal and gas outburst is the most dangerous..
