Cheng Jin'guo' Xu Liying' Chen Gao' (1.School of Mechanics and Ciavil Engineering China University of Mining and Technology Beijing 100083.China; 2.China State Construction Engineering Corporation Shandong Inrestment Co.Isd.Ji'nan Shandong 250101 China) Abstract:The main mechanism of TBM cutting rock is forcing the cutters to penetrate into rock mass and cut the rock block off the working face by use of cutterhead thrust and torque.Thus it is of great significance for tunnelling and cutting efficiency to improve the property and quality of disc cutters.Based on the TBM tunnelling project of the inclined shaft in Bulianta coal mine the cutting efficiency and wear condition of three kinds of cutters with different properties were investigated.The results indicated that the newly improved cutter A with higher yield strength and thicker cutter edge width has a lower wear quantity than traditional cutters B and C at a proportion of ...
