Evaluation of load transfer mechanism under axial loads in a novel coupler of dual height rock bolts
The effective reinforcement of two or more overlying layers of mine openings in a single installation is usually done by coupling of two standard rock bolts mainly during the extraction of medium-thick coal seams. However, field observations show that the couplers of multiple bolts often degrade or...
