松藻矿区羊叉滩井田煤层气赋存特征研究

Study on coal bed methane deposit features of Yangchatan Coalfield in Songzao Mining Area

为了研究煤层气资源赋存情况并探讨合理利用煤层气的有效模式,基于煤田地质勘探、矿井生产资料和实测煤层甲烷等温吸附数据,对松藻矿区羊叉滩井田煤层气的赋存特征进行了综合分析研究,指出井田内不仅煤炭储量丰富,而且煤层气赋存条件良好,煤层气资源丰富,具有良好的综合开发利用价值,但鉴于煤层气渗透率低,建议采用地面抽采与井下抽放联合开采模式。

In order to study the coal bed methane resource deposit conditions and to discuss the affective mode to rationally utilize the coal bed methane, based on the coalfield geological exploration, the mine production information and the site measured methane isothermy sorption data of the seams, the paper had a comprehensive analysis and study on the coal bed methane deposit features of the Yangchatan Coalfield in Songzao Mining Area. The paper pointed out that there were not only rich in coal reserves, but also good in coal bed methane deposit conditions in the Coalfield. The coal bed methane resources were rich and have a good development and utilization value. Due to the low permeability of coal bed methane, it is proposed to have a combined mining mode with a surface drainage and an underground gas drainage operation.
