The article presents numerical simulations of changes of the rock mass state around a directional well. The calculations were conducted with various material models of rock: the linear-elastic model...

The hazard maps and simulation of boulder trajectories result in risk maps to categorise the boulder risk as low, moderate, high or very high risk. The low to moderate risk categories are assigned catch berms and gabion mitigation...
