Abstract:

This paper, based on the abnormal methane area and coal dust while mining in low-methane mines, applies the coalbed injection at the working face in Cheji coal mine, which demonstrates this method can effectively decrease the methane concentration and coal dust. This method shall be used extensively.

Key words:

low-methane mine; comprehensive excavation; coalbed injection; coal  dust

摘要：

结合低瓦斯矿井瓦斯异常区域的治理以及综掘煤尘问题的实际情况，采用煤层注水技术，完成了煤层注水在车集煤矿综掘工作面的工程应用实例，得出煤层注水技术在永夏矿区可以有效降低瓦斯并减少煤尘的结论，具有很大的推广价值。
