| Abstract: | To overcome the shortcomings of the current measures to prevent coal and gas outburst for mine,the equipment,technological process and on-the-spot tests of hydraulic flushing technology is described in detail.The study shows that the application of hydraulic flushing technology in large tilt angle thin coal seam can effectively eliminate the stress outburst,largely release the gas in coal seam,remarkably improve the drainage effect of gas and well prevent and control the outburst.Also the cycle of coal unco... |
| Keywords: | hydraulic flushing large-tilt-angle and thin coal seam drainage effect |
