Experimental and numerical investigation on a novel support system for controlling roadway deformation in underground coal mines
Abstract Roadway stability in extremely soft coal mass is a typical challenge in deep underground mines, as the most widely adopted support structure such as rock bolting, compound support system normally fails. This paper proposed a novel prereinforcement method for coal roadway, that is, jet grout...
