黄陵二号煤矿综采工作面瓦斯灾害防治技术

摘要

根据黄陵二号煤矿的复杂地质条件，从工作面布置、灾害治理等方面进行了分析，对瓦斯治理技术和瓦斯抽放方法方面进行了论述，对瓦斯治理技术采用的本煤层预抽、边采边抽、高位裂隙抽放、上隅角埋管抽放等方法做了介绍，为类似条件工作面的安全回采提供了借鉴。%According to complex geological conditions of Huangling №2 Coal Mine , from the aspects of mining face layout and disaster control , the gas control technology and gas drainage method was discussed .The gas control technologies , such as coal seam gas pre-drainage , gas drainage while mining , high-level fracture gas drainage , upper corner gas drainage by buried pipe , were introduced .The research can provide reference for mine gas control in similar conditions .
