高瓦斯综放作业面上隅角瓦斯防治分析

Analysis of Gas Prevention and Control at Upper Corner of Fully Mechanized Working Face with High-gas

针对高瓦斯综放作业面上隅角瓦斯超限现象开展研究,结合具体工程实际,在分析井下上隅角瓦斯涌出变化规律的基础上,从多个角度对如何开展瓦斯防治提出相应举措,并对其治理效果进行分析,希望能够为其他矿井上隅角瓦斯防治工作的开展提供指导和借鉴。

This paper studied gas overrun phenomenon at upper corner of fully mechanized working face with high-gas, analyzed change rules for gas discharge at upper corner in underground coal mine combined with specific engineering practice, put forward corresponding measures on how to develop gas prevention and control from multiple perspectives, and analyzed the governance effects, which hope to be able to provide guidance and reference for gas prevention and control work in upper corner in other mines.
