    Multiscale Fracturing in Medium- to Low-Rank Coals and Its Implications on Coalbed Methane Production in the Baode Area, Eastern Ordos Basin, China by Wei Zhang, Baoshan Zhao, Qingfeng Zhang, Jikun Zhang, Ziling Li, Xiaoguang Sun, Mingming Yan

    Published 2022-01-01
    “…Herein, we present a case study, combining underground coal mine surveying and specimen, thin section, and scanning electron microscope observations for illustrating the ~m-, ~cm-, ~mm-, and ~μm-scale fractures present in the Baode area, eastern Ordos Basin, China. Then, the fracture connectivity is evaluated by helium permeability and mercury porosimetry measurement. …”
