Research on gas control technology of coal roadway driving strip in soft coal seam

In order to improve the gas control effect of the coal roadway driving strip, in 24223 transport lane of No.4 coal seam in 2130 Coal Mine in Aiweigou Mining Area of Xinjiang, by carrying out the hydraulic fracturing test based on directional long borehole to control gas in coal roadway strip, the effect of gas control was investigated. The test results show that compared with the traditional gas control method, the average gas extraction concentration and the average gas extraction purity of the directional long hole high pressure hydraulic fracturing technology are increased by 2.4 times and 4.0 times respectively, and the economic cost and time cost of the extraction standard are reduced by 80% and 67%respectively. It can effectively improve the gas control effect and reduce the cost of gas control.
