沙曲矿单一工作面推进度与瓦斯涌出量关系研究

Study on Relationship Between Advancing Rate of Single Coal Mining Face and Gas Emission Value in Shaqu Mine

为了弄清煤炭开采与煤层气开采的相互影响关系,文章以华晋焦煤集团沙曲矿24207工作面为研究对象,通过对瓦斯抽排数据的实测统计和理论分析,探讨了单一工作面推进度与瓦斯涌出量的相互影响,为煤与瓦斯共采的评价体系提供了数据和分析基础,以期对煤炭行业的发展趋势产生良性的促进作用。研究发现,适当加快工作面推进度有利于瓦斯抽采,同时增加了煤炭生产和瓦斯抽采的效率和产量,对于煤与瓦斯共采产生的是正效应。

In order to understand a mutual influence relationship between the coal mining and coal bed methane mining, base on No. 24207 coal mining face in Shaqu Mine of Huajin Coking Coal Group as a study object, with the site measured statistics and theoretical analysis on the gas drainage data, the mutual influences between the advancing rate and the gas emission value of the single coal mining face was discussed to provide the data and analysis basis to the evaluation system of the coal and gas simultaneous mining and in order to have a benign promoting effect to the development tendency of the coal industry. The study found that the advancing rate properly speeded up of the coal mining face would be favorable to the gas drainage, to increase the efficiency and production of the coal production and gas drainage and to have a positive effect to the coal and gas simultaneous mining.
