Division and Deposit Features of Gas Geological Unit in No. 2 Seam of Tao＇er Mine
Abstract：According to the gas geological conditions of No. 2 seam in Tao＇er Mine, the quantification theory was applied to screen the fac- tors affected to the gas content distribution of No. 2 seam in Tao＇er Mine. The factors were the geological structures, roof lithology, mag- matic rock intrusion and buried depth. The linear regression 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 weathered zone,Ⅱ unit was outburst dangerous zone and Ⅲ unit was outburst dangerous zone in potential.
