高瓦斯煤层综采工作面顺层长钻孔预抽瓦斯效果分析

Analysis of Long-hole Pre-Pumping Gas at Fully Mechanized Mining Face with High Gas Seam

高瓦斯煤层综采工作面回采过程中,瓦斯治理是保证安全生产的一个重要环节,综合采用采前预抽和边采边抽能有效地减少工作面回采期间本煤层瓦斯涌出量,确保高瓦斯煤层工作面的安全顺利回采,实现高产高效。

In the process of stop mining at high gas seam mining face gas control is the key to ensure safe production,comprehensive using pre-drainaging pump and mining and pumping can effectively reduce the mount of face gas outburst during the stop mining so as to ensure high gas face safe mining and achieve high yield and high efficiency.
