Division and Deposit Features of Gas Geological Unit in No.2 Seam of TaoDer Mine

According to the gas geological conditions of No.2 seam in Taoer Mine, the quantification theory was applied to screen the factors affected to the gas C ontent distribution of No.2 seam in TaoDer Mine.The factors were the geological structures, roof lithology, magmatic rock intrusion and buried depth. The linear regressio n model was applied to predict the gas along strike and tendency distribution law of each unit.No.2 seam was divided into three gas geological units. I unit was gas we athered zone, I unit was outburst dangerous zone and unit was outburst dangerous zone in potential.
