| 摘 要： | 通过对康家滩矿88203回采工作面尾巷瓦斯异常涌出进行考察、分析,表明大气压变化、顶板大面积冒落、采空区漏风和邻近层瓦斯涌出是回采工作面尾巷瓦斯异常涌出的原因,其中大气压的变化是最主要的原因。在分析结果的基础上提出了针对性的防治瓦斯异常涌出的技术措施。

| Abstract: | Investigation and analysis on the abnormal methane emission in 88203 coal face in Kangjiatan Mine were made in this paper, the study results showed that the barometric change, roof fall over great extent, the air leakage in the gob and the methane emission in the adjacent seam are all impact factors of abnormal gas emission in the tailgate of coal face. Of which the barometric change is the most important factor. On the basis of the analyzing results, the authors put forward the aimed techno-measures for the prevention and control of abnormal gasemission. |
