Abstract

To compare the rock-breaking characteristics of disc cutter under abrasive water jet-assisted and conventional working conditions, rock-breaking experiments under two working conditions were carried out. The differences in the rock-breaking state, disc cutter load, and rock-breaking efficiency were compared and analysed. The results show that compared with conventional rock-breaking of disc cutter, the rock-breaking of disc cutter under abrasive water jet-assisted can improve the ability of disc cutter to penetrate the hard rock, promote the expansion of cracks inside the rock interior, thereby generating large-size rock chip. The vertical and rolling force of the disc cutter under abrasive water jet-assisted is significantly lower than that of the conventional disc cutter rock breaking, with an average decrease of 39% and 25%. In addition, the amount of rock-breaking by disc cutter under abrasive water jet-assisted increases, and the rock-breaking efficiency is further improved, which is 1-2 times that of conventional rock-breaking of disc cutter. The research results provide a reference for improving the rock-breaking performance of disc cutters under hard rock geological conditions and efficient excavation of TBM.
