If depth is great and rock mass has rock burst properties, bump can occurs. The solution is based on experimental and mathematical modeling.These two methods have to allow the problem to be studied on the basis of three presumptions: the solution must be time dependent, the solution must allow the creation of crack in the rock mass, the solution must allow an extrusion of rock into an open space (bump effect)"@en . .
