摘要: 为了确保大采高综放工作面的顺利开采,分析了采空区瓦斯抽采技术,提出了具有可行性的瓦斯治理策略。
在开展瓦斯治理工作之前,通过增加风量和调整风路的流向,降低瓦斯聚集地的瓦斯浓度;在开展瓦斯治理工作之后,
将工作面瓦斯预先抽采与风路、风量、流向调节相结合,有效治理瓦斯,为煤矿的正常开采提供安全的环境。

Abstract: In order to ensure the smooth mining of fully mechanized caving face with large mining height, this paper analyzed the
technology of gas extraction in goaf and put forward feasible gas control strategies. Before carrying out gas control work, the gas
concentration in gas gathering area could be reduced by increasing air volume and adjusting the direction of air flow. After carrying
out gas control work, through the combination of pre-extraction of gas in working face with the regulation of air flow, air volume
and flow direction, gas control was effectively carried out to provide a safe environment for the normal mining of coal mines.

Key words: large mining height; fully mechanized caving face; gas control; pre-extraction
