“三软”特厚煤层高沼综放面瓦斯综合治理

Comprehensive Control of Gas at Fully-mechanized Caving Mining Working Face in Three-soft Thick Seam With High Content of Methane

通过对超化煤矿13011和21051两个开采条件相似的综放面瓦斯治理情况比较分析,得出瓦斯抽放是“三软”特厚煤层高沼综放工作面瓦斯综合治理的有效途径。

Conclusion is made that gas drainage is an effective way of comprehensive conrail of gas at rally - mechanized caving mining working faces in three - soft thick seam with high content of meththane by comparisons of gas control methods between two fully - mechanized caving mining working faces 13011 an 21051 with similar mining conditions.
