摘要
通过对康家滩矿88203回采工作面尾巷瓦斯异常涌出的考察、分析,分析结果表明大气压变化、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。提出了针对性的防治回采工作面尾巷瓦斯异常涌出的技术措施。
The uneven metnane emission of the 88203 coal mining face in kangjiatan mine is investigated and analyzed in this paper, the study outcome shows that the barometric change, roof fall over great exent, gob air leak and near seam methane emission are the impact factors. Thereinto, the barometric change is the most important factor, at last, we raised the aimed techno-measure to prevent the uneven methane emisson.
