突出煤层治理瓦斯巷道布置的研究与应用

Research and Application of Roadway Layout for Outburst Coal Seam to Control Gas

为了解决瓦斯制约矿井生产效率的问题,提出回采巷道增加布置一条瓦斯治理巷道的措施,并采取相关的瓦斯治理试验,在突出煤层采用顺层长钻孔水力压裂增透技术治理瓦斯试验成功后,利用瓦斯治理巷扩大突出煤层的瓦斯治理范围,保障安全生产。

In order to solve the problem of restrictions of gas on production efficiency of mines, this paper proposed that gas control roadway should be added in the stoping roadway and carried out related gas control test. The test of using hydraulic fracturing and long drilling along the seam to improve the penetrability of coal seam was proved to be successful. With the gas control lane,the scope of gas treatment in outburst coal seam was expanded to guarantee production safety.
