摘　　要：在综合分析宿东矿区的地质背景的基础上,通过对不同类型脆性变形构造煤的渗透性实验,并根据渗透性与有效应力之间的关系分析,研究了不同类型脆性变形构造煤渗透性之间的差异及其对煤层气开采的影响。结果表明脆性变形系列构造煤渗透率都比较大,随着有效应力的增大,构造煤的渗透率会减小。在相同压力点下碎斑煤的渗透率比较大,碎裂煤其次,然后是初碎裂煤,片状煤最小。Based on the comprehensive analysis of the geological background of SuDong mining area,through the experiment of the different types of brittle deformation of tectonic coal permeability,and according to the relationship between permeability and effective stress,The difference of permeability of structural coal with different types of brittle deformation and its influence on coal bed methane exploitation.The results show that the permeability of the tectonic coal in the brittle deformation series is relatively large.tectonic coal permeability will decrease with effective stress increasing.Under the same pressure point,it is found that the permeability of the broken spot coal is relatively large,the fragmentation of coal is the second,and then the initial fragmentation of coal.
