Abstract: Roof stability is a critical concern in coal mines, as the potential for roof collapse poses a significant risk to miners' safety and productivity. Roof stability is heavily influenced by the time-dependent properties of the… read more here.

Abstract: A tension cut-off (TC) technique becomes essential to account for the strength and failure characteristics of rock in low and tensile stress ranges, since that the generalized Hoek-Brown (GHB) criterion emphasizing shear failure. The synergistic… read more here.
