Influence of Motion Parameters on Cutting Performance of Boom-Type Roadheader During the Swing Cutting

The cutting performance of the boom-type roadheader impacts the energy consumption and efficiency of coal mine roadway excavation. The purpose of this work is to investigate the influence of motion parameters on cutting performance. The motion of the cutting head during swing cutting was simplified to establish a numerical model. Rock samples were arranged to perform the swing cutting to test the validity of the numerical model based on the...
