顶板近水平长钻孔替代闭式高抽巷进行瓦斯抽放的试验研究

Experimental research on using approximate horizontal long-hole instead of closed high extracted roadway to drain gas

    摘要
  • 摘要: 介绍了顶板近水平大直径长钻孔瓦斯抽放的试验情况,论证了长钻孔抽放瓦斯的可行性,认为采用“以孔代巷”抽放瓦斯这一新技术是合理的,并总结出了合理的钻进工艺参数。

     

    Abstract: In this paper,the experimental instance of using approximate horizontal roof long-hole to drain gas was introduced.The geological spot,the mechanism,the drilling technology with extraction-effect were contrasted and analyzed. The practicability of using long-hole to drain gas was testified.And reasonable drilling technology has been summed up.It provided reliable technique and theoretical foundation to popularize the gas drainage's new technique of ‘Long-hole Instead of Roadway’.
