Investigation of Alardinskaya mine coal bumps causes using computer simulation of rock massif stress conditionals

The purpose of the paper was to identify the causes of rock bumps that occurred at the Alardinskaya mine (Russia) in 2011. The research was carried out using the finite element method. The developed three-dimensional model of the rock mass included a coal seam, rocks bedding above and below, goaf, a...
