摘　　要：中国废弃煤矿数量巨大且多为高瓦斯矿井,综合考虑废弃煤矿瓦斯赋存的利弊及其时效性特点,认为亟需对废弃煤矿瓦斯资源进行开发利用。从废弃煤矿瓦斯资源开发利用的2个关键步骤:废弃煤矿瓦斯资源评价、瓦斯抽采利用入手,系统汇总分析了当前废弃煤矿瓦斯赋存范围、瓦斯来源及赋存状态、瓦斯资源量估算模型、瓦斯富集分布规律及抽采布井优化方面的研究进展,得出了废弃煤矿瓦斯资源评价及抽采利用方面存在的问题及研究方向。China has a large number of abandoned coal mines,many of which are highly gassy mines.Considering the pros and cons of gas occurrence in abandoned coal mine and its timeliness characteristics,it is considered that there is an urgent need to develop and utilize gas resources in abandoned coal mines.This paper starts with two key steps of gas resource development and utilization in abandoned coal mine:gas resource evaluation,gas extraction and utilization in abandoned coal mine,to systematically summarize and analyze the current research progress in gas occurrence scope,gas source and gas occurrence state,gas resource estimation model,gas enrichment distribution law and optimization of extraction well distribution.The existing problems in the evaluation,extraction and utilization of gas resources in abandoned coal mines are obtained,and the next research direction is pointed out.
