Currently, several underground mines adopt the underground mining method known as Cut and Fill. This is dues to the geological conditions of the deposit, which presents ore with a width of less than 0,50 m. However, as these mines reach depths greater than 1000 m, it is observed that the rock mass exhibits a fragile behavior, completely altering the mining conditions, resulting in rockburst events. These events consist of the ejection of blocks of rock capable of harming the mining business, causing delays in extraction, loss of equipment, or even loss of human lives. The objective of the project is to perform a back analysis of the rockburst events that have already occurred., using the Method Finite Element and Discrete Element (FEM/DEM). Additionally, it aims to determine the main orientation of the stresses affecting the contour of the underground excavations and calculate the values of ejection velocities, which will influence the value of the accumulated kinetic energy, at the contour of the underground excavation. It will also determine the behaviour of velocity curves according to the values of the friction angle obtained from geotechnical mapping. Finally, the values and dynamic support capacity required at deep levels will be defined to achieve a flexible behaviour in the choice of support type used.
