Study on Gas Geological Law of No.19 Seam in Baliancheng Mine

WANG Qing-yuan1,YANG Tian-hong1,LI Tie-liang2,PIAO Cheng-hao3,WANG Peng-li3(1.Research Center of Rock Fracturing and Stability Lost,Northeastern University,Shenyang 110004,China; 2.Shenyang Research Institute,China Coal Technology and Engineering Group Corporation,Shenyang 110016,China; 3.Hunchun Coal Mining Group Corporation Ltd.,Hunchun 133300,China)  
In order to prevent and control the gas disaster,according to the gas content,gas pressure and other data measured from No.19 seam,in combination with the mine geological conditions,the gas geological law was analyzed.The multi element regression analysis method was applied to predict the gas content and predict the danger of the coal and gas outburst.The result showed that the surrounding rock lithology of the roof and floor in No.19 seam was compact,the permeability was poor and the sealed condition was excellent.The gas content of the seam in a magmatic rock intrusion area would be increased and increased with the depth increased.Due not to meet the requirement of a single item index,No.19 seam would not have the danger of the coal and gas outburst and the key area of the gas control would be the magmatic rock intrusion area.
