Numerical modelling of discontinuous rock mass
Numerical modelling of rock masses in coal mines has been used ever since such models were first introduced into rock mechanics. In many cases, the behaviour of rock masses is controlled by the discontinuities present in the rock. Because of the limitations of classical numerical methods in terms of discontinuities, new discontinuum modelling approaches have been explored. The methodology applied consisted of the development and testing of three approaches: geometrical modelling, a stability method with equilibrium limit, discrete element methods. This methodological study allows the extension of the use of block modelling for forecasting the strata control stress in coal mines. Many applications are currently in use in underground and open cast mines.
