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

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 W ith the mine geological conditions, the gas geological law was analyzed.The multi element regression analysis method was applied to predict the gas content and predic t 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 p oor 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 b e the magmatic rock intrusion area.
