A Practical Nonprobabilistic Reliability Assessment Method on Key Strata Shear Failure in Longwall Mining
Roof cutting has long been a potential hazard factor in longwall panels in some diggings in China. Meanwhile, the key strata structural reliability, which provides an assessment on the stability of overlying roof strata, may be a significant reference for support design in underground coal mines. Th...
