Experimental and numerical investigation of roadheader for breaking rock containing predrill holes
Abstract The purpose of this study is to investigate the dynamic characteristics of a roadheader for breaking rocks containing different numbers and sizes of predrill holes. A series of experiments was performed to quantitatively measure the cutting torque, thrust force, and specific energy during t...
