煤层气开发过程中，由于各煤层及其顶底板之间物性特征等方面的差异，易导致层间干扰，影响煤层气产能。阳泉矿区煤层气资源储量丰富，主要可采煤层有3#、8#、9#、15#煤层，其中3#煤层为局部可采煤层。以该区YQ-191和YQ-359井为例，通过分析8#、9#、15#煤层在渗透率、储层压力、煤层厚度、含气量、埋藏深度、水文地质条件的差异,发现,YQ-191井8#、9#的各项参数较为接近，层间干扰小，适宜合层开采；YQ-359井8#、15#煤层渗透率与储层压力相差较大，层间干扰严重，合层开采严重影响15#煤层的产能，该井8#、15#煤层不适宜合层开采。

During CBM exploitation process, owing to physical property characteristic differences between coal seams, roofs and floors are easy to produce interlayer interference and impact CBM production capacity. The Yangquan mining area possesses of abundant CBM resources and reserves, main mineable coal seams have Nos.3, 8, 9 and 15, in which, No.3 is locally mineable. Taking the wells YQ-191 and YQ-359 as examples, through analyses of coal Nos.8, 9 and 15 differences in permeability, reservoir pressure, coal seam thickness, methane content, buried depth and hydrogeological condition have found that coal Nos.8 and 9 in well YQ-191 are relatively in close proximity, thus small interlayer interference, thus adaptable for commingled drainage. While coal Nos. 8 and 15 in well YQ-359 have larger differences in permeability and reservoir pressure, thus serious interlayer interference and impact production capacity, adverse to coal No.15 drainage.
