在我国即将面临“低碳经济”重大历史机遇的新形势下，河南省“三软”煤层瓦斯综合利用越来越显示其重要性。根据焦作煤田与邻近矿区的地质构造资料以及相应瓦斯抽放试验结果，选择核心区块九里山井田为试验区，分析了主采二1煤储层的渗透性能与顶板盖层构造条件，并且依次探讨了煤层气远景开发的可行性。数值模拟结果表明：注水压裂开采条件下，由断块构造控制的九里山井田煤层气抽采衰减周期大约为15a，单井平均日产量可达439m3/d，平均采收率可达36%左右，可采储量达402.62×106m3，完全满足规模利用的开采技术指标。

Under the new situation of“low carbon economy”significant historic opportunity the country will face, comprehensive utiliza-tion of“three soft”(soft coal seam, roof and floor) area coal seam gas more and more shows its significance. Based on geological struc-tural data and corresponding gas drainage tested results in the Jiaozuo coalfield and neighboring mine areas, taking the kernel block Ji-ulishan minefield as test area, analyzed permeability and cover rock structural condition of main mineable coal II 1 reservoir, discussed CBM long-range perspective exploitation practicability in turn. The result of numerical simulation has shown that during hydraulic frac-turing exploitation, methane drainage attenuation cycle is about 15 years in the fault block controlled Jiulishan minefield. Single well average daily yield can be 439m3/d as high;average recovery ratio about 36%;recoverable reserves 402.62×106m3;thus can fully satisfy scaled utilization mining specifications.
