Experimental study on wear of TBM disc cutter rings with different kinds of hardness
Tunnelling and Underground Space Technology, 2018To study the wear characteristics of disc cutter rings, cutter-rock wear tests between cutter rings with six types of hardness and three typical types of rock are carried out based on the liner cutting machine (LCM). The wear mechanism and wear depth are
