Gas Deposit Influence Factors Analysis of Xinjiang Fukang Mining Area

The gas content is low in mid-low rank coal of Xinjiang, the early exploration development and research is not given sufficient attention. With the coal mining depth deepening in recent years, the gas accidents cause huge casualties and economic losses. The gas deposit is affected by multiple factors of mid-low rank coal, the thrust fault seam closeness and tectonic coal cause gas gather in the near fault seam. As the depth increasing, the concentration of the gas content increases. The gas is effectively blocked by roof and floor mudstone, sandy mudstone and groundwater. In addition, it is found that the air produced by multiple zone burning can displace the gas through further research, which causes dense burnt rock to plug gas. These factors result in gas enrichment in Fukang Wugong, Dahuangshan, Xigou, Xinshiji ming area, thus the fire - hydraulic block - fault type coalbed methane reservoir forms, which provides the basis for the safe production and gas exploration development of coal mines.
