摘要
四川煤矿矿井井型小,煤层薄、构造复杂、渗透性差,瓦斯灾害严重又难于抽采。本文从管理和技术角度对四川近几年的煤矿瓦斯抽采利用工作进行了总结。
Coal mines in Sichuan are characterized by small mine size, complicated structures, thin coal seams with low permeability and severe gas hazards, which are difficult to drain gas. The paper summarizes the gas drainage and utilization of CMM in Sichuan in the recent years from administration and technical viewpoints.
