摘要
为了科学判断平煤十一矿己二采区西翼己16,17煤层-850 m以上的煤与瓦斯突出危险性,对其瓦斯压力、瓦斯含量、瓦斯放散初速度、煤的坚固性系数等瓦斯参数进行了测定,根据《煤与瓦斯突出矿井鉴定规范》和《防治煤与瓦斯突出细则》的相关规定,科学合理地评价了-850 m以上己16,17煤层的突出危险性。实践表明,该评价方法为区域性突出危险性不明的煤层提供了可靠的判断手段。
In order to acquire coal and gas outburst danger of F16,17 coal seam above -850 m in F2 mining area west wing of Pingdings-ban 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＂ and＂ Prevention 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.
