摘　　要：以新安矿区二1煤层为研究对象,基于区内煤田地质勘查、煤炭资源开发资料,结合区内煤矿井观察,分析了煤储层和煤层气分布特征,估算煤层气总资源量347.80×10^8m^3,资源丰度0.6144×10^8m^3/km^2。选取地质构造、埋深、煤厚、渗透率、储层压力、资源丰度6个要素对该区煤层气资源潜力进行评价,综合评价认为KD1、KD3属较有利区,其他属潜力区。TakingⅡ1 coal seam in Xin′an Mining Area as the research object,based on the data of coal geological exploration and coal resources development in the area,combined with the observation of coal mines in the area,the distribution characteristics of coal reservoirs and coalbed methane were analyzed,and the total resource of coalbed methane was estimated to be 347.80×10^8 m^3,and the resource abundance was 0.614 4×10^8 m^3/km^2.The potential of CBM resources in this area was evaluated by six factors,including geological structure,burial depth,coal thickness,permeability,reservoir pressure and resource abundance.The comprehensive evaluation showed that KD 1 and KD 3 belong to more advantageous areas,while others belonged to potential areas.
