Modelling of Rock Cutting with Asymmetrical Disc Tool Using Discrete-Element Method (DEM)

Abstract The use of asymmetrical disc tools for the mining hard and very rocks is a promising direction developing mechanical methods. A significant obstacle in methods with asymmetric lack adequate computational deep understanding rock–tool interaction can develop industrial applications significantly. fundamental problem designing work systems analytical models to identify tool loads during process. One reasonable approach computer simulation. purpose research was simulation model rock cutting using an then evaluate developed model. In article, Discrete-Element Method (DEM) LS-Dyna adopted simulate tools. Numerical tests were conducted by pushing into sample at given distance from edge until material detached entirely. Two types samples used tests: concrete sandstone. independent variables study diameter cut spacing. To validate model, analogous laboratory carried out. article presents comparison results tests. showed good accordance experimental studies. proposed test be input data on larger scale. Thus, it will possible consider complex kinematics dynamics rock-mining process DEM
