中文摘要：
水文地质条件对煤层气的富集高产起着重要的控制作用。在系统研究焦作矿区水文地质特征的基础上，分析了水文地质条件对煤层气赋存、渗流、运移及煤层气生产的影响。焦作矿区水文地质条件，整体上有利于煤层气的赋存，但局部地下水强径流带，煤层气以水流为载体被逸散；岩溶裂隙发育区，煤系埋藏较浅而且又接近地表水体的区域，断裂发育且有可能成为导水通道的区域，地表水可能进入煤层，不利于煤层气的开采。煤层气勘探开发选择井位时，在其他条件相同情况下，煤层气井应选择在离断层较远的稍深部位。煤层气生产应合理处理可能造成的环境地质问题。
英文摘要：
Hydrogeological conditions play an important role in high concentration of coal-bed methane. Based on the systematic study of hydro-geological characteristics in Jiaozuo Mining Area, the influence made by hydrogeological conditions on the occurrence, seepage, migration, recoverability and production of coal bed methane was analyzed. Hydrogeological conditions in Jiaozuo are over ally beneficial to the occurrence of coal bed methane, but in the strong runoff zone with local groundwater, coal bed methane migrate taking water flow as a carrier. Karsts-cranny developing area, coal region of measures exposed or buried in shallow and also closed to the surface water, which can flow into the seam through fissures will adversely affected coal bed methane mining. More developing fractures may become the water-channels, so when we select wells for coal-bed methane exploration and development, at the same conditions of other cases, the coal bed methane wells should be selected in deeper and more distant from the site of the fault. Coal bed methane production should be reasonable to deal with potential environmental geological problems.
