Comparison with numerical models and tributary area theory . Comparison of pillar stress calculated by PAt and numerical models is made in [Poulsen 2010] and in the numerical models constructed after both the 1988 and 2008 subsidence events at Collingwood Park.
These problems indicate that the whole issue of rock characterization should be realized and adjusted for using different methods of numerical modelling. The use of different numerical models requires different types of rock mass characterization. Therefore the success of a numerical model is in capturing the rock reality characterization ...

When constructing numerical model, particular attention should be paid on selection of: appropriate geometry of model, proper constitutive model describing behavior of rock and soil layers, adequate values of rock mass parameters prior to execution of mining exploitation, and after it.
Abstract. Numerical modelling has been used to investigate a variety of problems in underground mining and tunnelling: subsidence induced by longwall coal mining; stresses generated when an open stope is filled cemented backfill and the stability of exposures created during subsequent mining of adjacent stopes; the interaction of two tunnels; and the effects of undermining a preexisting ...

In geology, numerical modeling is a widely applied technique to tackle complex geological problems by computational simulation of geological scenarios.. Numerical modeling uses mathematical models to describe the physical conditions of geological scenarios using numbers and equations. Nevertheless, some of their equations are difficult to solve directly, such as partial differential equations.
