    Experimental Study on Shear Characteristics of Coal Samples in Different Water-Bearing States by Yang Wu, Lujun Wang, Baoyang Wu, Ze Xia

    Published 2024-01-01
    “…Additionally, scanning electron microscope analysis revealed significant changes in the microstructure of coal samples under different moisture states: as the moisture content and dry-saturation cycles increase, the microstructure of the coal samples gradually transforms from orderly and compact to disordered and murky, elucidating the mechanism by which moisture weakens the mechanical properties of the coal samples. …”
