抄録

With increasing use of mechanical excavation techniques in mining and civil engineering projects, it has become increasingly important to understand the fracture mechanisms involved in disc cutting. Two-dimensional Discrete Element Modeling has traditionally been used with some success in illuminating fracture behaviors; however, rock fracturing is an inherently three-dimensional problem with challenges including matching the bulk properties of real rocks and cutting down computation time by reducing the number of particles needed to obtain realistic results. In this paper we discuss some of the challenges facing three-dimensional modeling of rock cutting. Additionally, we suggest the potential for alternative solutions such as boundary conditions and tensile strength calibration as a preliminary step toward a full three-dimensional understanding of rock fragmentation.
