The objective of this design is to integrate uncontrollable parameters of the rock mass and controllable ones, which are the geometric parameters of the mesh. In addition, using specialized software, the blasting performance is evaluated to generate a prediction of the P80, the impact of the VPP, and its feasibility according to the economic requirements.
