摘要
钻孔的合理封孔深度不仅是瓦斯抽放的一个重要环节,而且是提高瓦斯抽放效率的关键;采用合理测定"三带"的方法,在顾桥矿1117(3)工作面进行了试验,通过数值模拟软件的模拟,得出了顾桥矿1117(3)工作面预抽钻孔的合理封孔深度,从而为高效的实现瓦斯抽放打下坚实的基础。
The reasonable depth of sealing hole is not only an important part of gas drainage, but also a key to improve the efficiency of the gas drainage. In this paper, a reasonable determination of the " three zone" was used to test the 1117 (3) face in Guqiao mine. At last, the logical depth of sealing hole of the coal seam gas drainage was obtained through the simulation of numerical simulation software, which lay a solid foundation on the efficient gas drainage.
