摘　　要：对瓦斯抽采与利用技术的现状进行了归纳总结,分析了目前在瓦斯抽采和利用方面存在的问题,认为在瓦斯综合抽采中需要注意抽采方法的优化设计组合,以及钻孔参数和封孔技术的优化,加强低渗透煤层瓦斯抽采技术的研究与投入;在瓦斯利用中应该加快低浓度瓦斯气利用技术的示范与推广,引进和研究超低浓度瓦斯气利用新技术,拓展瓦斯的利用范围,才能达到煤矿灾害防治、伴生资源利用与生态环境保护的最终目标。The current technologies of gas extraction and utilization were summarized, and some existing problems were analyzed in this paper. During the comprehensive extraction of gas, the combination of different methods is very important, parameters of drill hole and hole sealing technology also should be optimized. Gas extraction of low-permeability coal bed is still a difficulty, which needs more research and input. The demonstration and popularization of low concentrated gas utilization should be accelerated in gas utilization, as well as introducing and studying new technology for ultralow concentrated gas utilization, exploring gas utilization scope to achieve all the alms of coal mine disaster prevention and control, associated resource utilization and ecological environment protection.
