摘要
针对瓦斯严重威胁工作面开采和作业人员人身安全的问题,急需一套有效的防治措施解决工作面瓦斯突放事故的发生。以某矿为研究对象,在分析其煤层、地质、瓦斯等情况的基础上,提出将保护层先行开采和预抽放技术应用于防治工作的思路,并确定了具体防治方案。经实践表明,所提出了两项防治技术能够达到对瓦斯的明显治理效果。
In view of the serious threat of gas to the working face mining and the personal safety of operators,it is urgent to take a set of effective prevention and control measures to solve the occurrence of gas outburst accident in working face.Taking a mine as the research object,based on the analysis of its coal seam,geology,gas and other conditions,this paper puts forward the idea of applying the protective layer first mining and pre-drainage technology to the prevention and control work,and determines the specific prevention and control scheme.The practice shows that the two prevention and control technologies can achieve obvious gas control effect.
