    Adsorption Respondence of Different Coal Body Structures and Its Influence Mechanism

    • 摘要: 为了研究不同煤体结构煤的吸附行为差异和作用机理, 以焦作煤田为研究区, 对煤体破坏严重的糜棱煤和原生结构煤的岩石学组成、吸附性和孔隙性进行了测试, 结果表明: 煤体破坏后, 吸附、解吸能力增大; 温度增加, 煤的吸附能力均为下降, 解吸能力增加.相比于原生结构煤, 随着温度增加, 糜棱煤吸附能力下降趋势和解吸能力增大趋势比原生结构煤更为明显.研究认为: 煤体破坏后, 不同孔径段的孔隙数量均有增大, 使得煤样容纳气体的能力增大.特别是大中孔含量的增大, 导致了糜棱煤样更容易发生解吸.另外, 煤体破坏后的煤级增高、镜质组含量增大和惰质组含量减小也对吸附能力增大具有重要作用, 而灰分含量不是决定两类煤吸附性差异的主要因素.
