| 摘 要： | 芦岭煤矿是我国典型的高瓦斯突出矿井，煤层变形复杂，含气量高，渗透率低，煤层气丰度高，抽采难度大，有利区块优选对于煤与煤层气协调开发至关重要。在深刻剖析构造、煤厚、气含量等储层地质特征、研究影响主采煤层煤层气运移富集地质因素的基础上，运用层次分析法计算出各影响因素的权重，通过综合定量评价．提出煤矿北部C区是地面煤层气开发的最有利块段。

| Abstract: | The Luling coalmine is a typical high-gassy outburst-prone mine in China. Coal seams in the mine have been complicatedly deformed, with high gas content, low permeability, high CBM abundance, but difficult to drain out. Thus advantaged sector optimization is of great concern to coal and CBM coordinative exploitation. Based on analyses of reservoir geological characteristics including structure, coal seam thickness, gas content, and study of geological factors impacting CBM migration, enrichment in main mineable coal seams in detail, then using AHP computes weight of each contributing factor. Through comprehensive quantitative evaluation, point out the C sector in the north part of the coalmine is most advantaged sector to carry out surface CBM exploitation. |
