高瓦斯煤层边采边抽效果分析

Coal Methane Extraction Analysis during Coal Being Mined in Rich Methane Coal Seam

在高突煤矿生产过程中,治理瓦斯是保证安全生产的一个重要环节,特别是高瓦斯煤层在掘进期间,边掘边抽也是治理瓦斯的一种有效手段。在回采过程中,由于区域瓦斯储量大,工作面瓦斯超限,采取边采边抽的方法能够解决工作面瓦斯超限。

In the production of high outburst coal seam, the methane management is a key link of ensuring safe production. In the mining process, the face methane is overrun because the methane reserves is large. The problem of face methane overrun can be solved by adopting the way of drainage and mining.
