摘　　要：以寺河矿高突矿井为例,基于其现实条件,为解决大采高工作面瓦斯超标的问题,对高突矿井大采高工作面瓦斯抽采实践进行了研究。通过对3种瓦斯抽采方式的对比分析,发现最为有效的是顶板走向长钻孔抽采。该措施落实后,瓦斯体积分数控制在了安全范围之内,为矿井工作的安全开展提供了有效保障。Taking a high outburst mine of Sihe Coal Mine as an example, based on its actual conditions, this paper studied the gas drainage practice of working faces with large mining height in the high outburst mine, in order to solve the problem of gas exceeding the standard in working faces with large mining height. Through the comparative analysis of the three methods of gas drainage, it was found that roof-trending long borehole drainage was most effective. After the implementation of this measure, the gas volume fraction was controlled within the safe range, which can provide effective guarantee for the safe development of mine work.
