摘要
以侯甲煤矿为例,对高瓦斯矿井的瓦斯防治技术进行了研究,介绍了侯甲煤矿在瓦斯防治方面所采取的主要技术措施和防治经验,包括通过优化巷道布置来提高通风系统的通风效果和通过大面积施工煤层瓦斯抽放钻孔进行瓦斯预抽,降低煤层的瓦斯含量。
Taking Houjia Coal Mine as an example, this paper studies the gas control technology in high gas mine, introduces the mainly adopted technical measures and experiences in gas prevention and control in Houjia Coal Mine, including two aspects of improving the ventilating effect of the ventilating system through optimizing roadway layout and reducing the gas content of coal seam through gas pre-drainage in large area gas drainage drilling construction of coal seam.
