    Bending Moment Characteristics of Hard Roof before First Breaking of Roof Beam Considering Coal Seam Hardening by Shitan Gu, Bangyou Jiang, Yue Pan, Zheng Liu

    Published 2018-01-01
    “…Considering the strain hardening effect of coal seam, the support pressure relationship of three zones—softened, hardened, and elastic—of a coal seam with regard to a hard roof is proposed, and methods to determine an approximate expression for the support pressure of hardened zone of coal seam, the range of hardened zone, and the corresponding peak values of support pressure are provided. The deflection equations of a hard roof under three different support pressure relationships of coal seam before the first breaking were theoretically derived, and all the relevant integration constants were determined. …”
