摘要:煤矿区煤层气的开发部署, 受煤炭采掘规划和采掘布置的影响。基于我国目前的煤层气勘
探开发现状, 以晋城矿区为例, 提出了煤层气开发部署原则, 设计了井网优化部署方案, 并进行了
开发潜力及瓦斯治理效果分析。随着煤炭采掘的不断推进, 煤矿区煤层气开发的地面垂直井形式
会发生变化, 即由起初单纯的地面垂直井转化为地面采动区井, 而后可转化为地面采空区井。在地
面垂直井阶段, 气井连续排采 10 a, 累计产气量为 ×104 m3, 目标煤层瓦斯含量降幅约为
%~%。通过地面采动区井和地面采空区井阶段的瓦斯抽采, 可使瓦斯抽采率进一步提高,
达到有效治理瓦斯的目的。

Abstract:According to the analysis of status on CBM development in China, method on well pattern arrangement
of CBM development in coalmine area is studied. The arrangement of well pattern is controlled by plan and design
of coal mining. Based on the plan and design of coal mining and the geological conditions of Jincheng coal mine
area, the principles of CBM development in coalmine area are analyzed, and the well pattern arrangement is de-
signed, and potential of CBM development and effect of gas control are
