摘要
根据煤层瓦斯含量井下直接测定方法,在江西英岗岭煤业有限责任公司桥二煤矿一井1220顺槽、东村煤矿4207顺槽进行了现场试验测定解吸瓦斯量,并通过经验公式计算煤层瓦斯含量,试验效果误差范围基本符合矿井实际,并大大地节约了试验成本。另外,对测定中误差影响因素进行了分析,对试验操作者有一定的指导作用。
The direct way of measuring the coal seam gas content underground is used to determine the desorp- tion content of gas by field test on 1220 working face of No. 1 mine in Qiao＇er Colliery and 4207 working face in Dongcun Golliery of Jiangxi Yinggangling Coal Industry Ltd. , Co. , during which the coal seam gas content is calculated by empirical formula, showing the error range of the test result basically conforms to practices of mine, and greatly saving the experimental cost. Moreover, the analysis of error influential factors in the test provide a certain directive guidance for the experiment operator.
