摘　　要：近年来,我国煤炭开采工艺进步显著,而对于厚煤层来说,分层开采技术的应用大大降低了煤炭开采工艺难度,提升了煤炭开采效率,为企业带来了良好的经济和社会效益。但是,厚煤层分层开采过程中,下分层瓦斯大量涌入回采工作面,其中的瓦斯治理情况形式严峻,为确保高瓦斯厚煤层分层开采过程中能够有效进行瓦斯防治,需要对其相关技术进行深入研究。论文分析了高瓦斯厚煤层开采技术及瓦斯事故原因,提出了开采过程中的瓦斯防治技术措施。In recent years, China’s coal mining technology has made remarkable progress. For thick seams, the application of stratified mining technology greatly reduces the difficulty of coal mining technology, improves the efficiency of coal mining, and brings good economic and social benefits to enterprises. However, in the process of thick seam slicing mining, a large number of lower slicing gas pours into the mining face, and the form of gas control is severe. In order to ensure effective gas prevention and control in the process of high gas thick seam slicing mining, it is necessary to conduct in-depth research on its related technologies. In this paper, the mining technology of high gas thick seam and the causes of gas accidents are analyzed, and the technical measures of gas prevention and control in the process of mining are put forward.
