Coal and Gas Outburst Danger Evaluation of F_(16,17) Coal Seam Above-850 m in Pingdingshan No.11 Coal Mine

Che Yun-li

Abstract

In order to acquire coal and gas outburst danger of F16,17 coal seam above-850 m in F2 mining area west wing of Pingdingshan No.11 Coal Mine,the coal gas parameters such as gas pressure,gas content,the beginning of the gas emission rate and coefficient were determinated.According to the interrelated standards of Mines of Coal and Gas Outburst Identification Norms andPrevention and Control of Coal and Gas Outburst Rules,scientific and reasonable evaluation on the risk of the area above-850 m of F16,17 coal seam of F2 mining area were given in the article.Practice shows that the method of the evaluation provide reliable judgement method for coal seam which has indefinite regional outburst danger.
