The influence of deformational parameters of a numerical model on the subsidence basin profile for chosen working depths

Piotr Kołodziejczyk, Marek Wesołowski

Abstract

The basic problem of numerical modelling of a mining area subsidence is the choice of model parameters values enabling reproduction of relations between maximum subsidence, working depth and maximum gradient observed in practice. The article characterises the fluctuation of the deformation Gxy/Gxz parameters ratio in order to achieve various gradients of subsidence basin profile for chosen mining depths. The data analysis was based on the commonly used tgβ parameter.
