| 摘 要： | 河北省煤层气资源分布总体呈现南高北低、东高西低的趋势，煤层气集中在邯峰矿区-开平煤田的NE向带状区域。通过对省内4个重点区及5个一般地区煤层资源评价，底板标高-2000m以浅的煤层气资源总量为6046．32亿m^3，可采资源量为2523亿m^3，主要分布在底板标高为-1500m～-2000m的煤层中。根据煤层气资源和煤储层物性特征，认为峰峰矿区是河北省煤层气勘查开发的有利地区。在大淑村、小屯矿等无烟煤、贫煤发育区，可实施短半径水平分支井；在煤层气富集、渗透率适当的中煤级煤地区，可以实施垂直井或井组；在高瓦斯的煤矿开拓区，可以采用三维立体的煤层气（瓦斯）抽采模式。

| Abstract: | The distribution of CBM resources in the Hebei Province reveal itself a high in south and east, low in north and west tendency, concentrated in Handan-Fengfeng mining area and Kaiping coalfield, both are NE direction zonal areas. Estimated CBM resources in 4 provincial key areas and 5 generic target areas have 604.632 billion m^3 above the -2000m level, mineable 252.3 billion m^3 mainly hosted in -1500m--2000m coal seams. According to resource and coal reservoir physical characteristics, think the Fengfeng mine area is a favorable area for CBM exploration and exploitation in the province. In Dashueun, Xiaotun coahnines anthracite and meager coal areas can use short radius horizontal multilateral well mining; in CBM enrichment, moderate permeability middling coal ranks areas can use vertical wells or well groups mining; in gassy coalmine development areas can use 3D CBM （gas） drainage mode. |
