摘要
通过对上社煤矿2009年的瓦斯等级鉴定结果进行认真总结分析的基础上,根据《矿井瓦斯等级鉴定规范AQ1025-2006》的有关规定,分析了2006年以来上社煤矿历年来相对瓦斯涌出量和绝对瓦斯涌出量的变化趋势,研究了瓦斯等级鉴定工作中所存在的主要问题及原因,并提出了做好瓦斯等级鉴定工作的几点建议:增加各煤层、各采区和各水平的瓦斯涌出量及其所占比例大小分析,以月平均日产煤量作为相对瓦斯(二氧化碳)涌出量的计算依据,将瓦斯抽采系统的停运时间扣除,对于低瓦斯、高二氧化碳矿井,必须以二氧化碳为主要测定指标。
Base on the serious summarization and analysis on the mine gas grade appraised results of Shangshe Mine in 2009,according to the related regulations of ＂the Mine Gas Grade Appraisement Code AQ1025-2006＂,the paper analyzed the variation tendency on the annual relative gas emission volume and the absolute gas emission volume in Shangshe Mine since 2006,studied the main problems and causes existed in the mine gas grade appraisement work and provided the several proposals to well conduct the mine gas grade appraisement work.The proposals were to increase the analysis on the gas emission volume from the each seam,each mining block and each level and the percentages,to take the average daily coal production per month as the calculation basics of the absolute gas（carbon dioxide） emission volume and to deduct the stop time of the mine gas extraction and drainage system.As for the mine with low gas and high carbon dioxide,the carbon dioxide shall be the main index to be measured.
