The Effect of Pick Profile on the Cutting Performance of Point Attack Picks

Abstract:

Tungsten carbide tipped pointed attack picks is widely used in mechanical machinerysuch as roadheaders, continuous miners and longwall shearers. Great efforts have been made toinvestigate the interaction between point attack pick and rock. However, the research on theinvestigation of pick profile on the cutting performance is still a subject little investigated by thescientific community. In this study, the rock fragmentation process is simulated using a 2D discreteelement code, PFC2D. In the simulations, four types of pick tip geometries (mushroom insert, bulletinsert, conical insert, and cap) were employed to investigate the effect of pick profile on the cuttingperformance of point attack picks. The forces acting on the pick and crack propagation process werecontinuously monitored during the simulations. The preliminary results of cutting performance ofthe picks under different cutting scenarios were analyzed.
