抄録

A rock cutting rig has been designed and installed to investigate disc cutter performance in circular cutting mode as well as in linear one. A program of disc cutting experiment was performed in the circular cutting mode by using a single commercial disc cutter of diameter 150 mm and edge angle of 90° for seven different types of rock. The experiments resulted in determining semi-empirical formulae for thrust FT, rolling force FR and lateral force FL acting on a disc cutter, written by FT=KTD1/2P1/2S1/2FR=KRPS1/2FL=KLP3/2<BR>where D is a diameter of disc cutter, P is penetration of disc cutter and S is tool space. The coefficients of KT and KR correlate not only with strength property of rock such as fracture toughness and uniaxial compressive strength, but also with the stiffness property of rock. The coefficient KL depends exclusively on the fracture toughness of rock These results do not conflict with those obtained from laboratory experiments using linear cutting rigs.
