以岩保煤巷道抽放方式的研究

摘　要:高瓦斯突出煤层的煤巷掘进工作面必须进行打钻预抽,采用从邻近的超前掘进岩巷打钻抽放煤巷掘进工作面瓦斯既可不影响煤巷的正前掘进,又可保证充足的抽放时间,不受生产压力制约,能真正意义地保证抽放达标,解决了煤巷抽放影响生产的传统问题。

分类号:　TD712Study on the Roadway Drainage Way of Protecting Coal with RocksJIA Yong-bin (Shanxi Hongxia First Construction Co. Ltd., Yangquan 045000, Shanxi, China)Abstract:The roadway heading face of high gas-burst coal seam must be drilled for pre-pumping. Drain the gas of roadway heading face by drilling from the from the neighboring advance development rock roadway not only does not affect the front excavation of coal roadway, but also can ensure adequate drainage time without the constraints of production pressure, and ensure the drainage to reach the standards in true meaning, which has solved the traditional problems of coal roadway drainage affecting the production.
