    Study on the depth and pattern of floor failure in closely spaced bifurcated coal seams by LIANG Bing, CHEN Xintao

    Published 2025-06-01
    “…Due to the complex geological characteristics of bifurcated coal seams, the variable relative dip angles and spacing between the upper and lower seams lead to a floor structure that differs significantly from those considered in previous studies, making it difficult to directly apply existing formulas to calculate the floor failure depth. To address this issue, this study took the 3-1 bifurcated coal seam in Holuowan Coal Mine as the engineering background and derived the theoretical solutions for the maximum failure depth under three failure scenarios of closely spaced bifurcated coal seams, based on the plastic slip line field theory for a single rock layer. …”
