Abstract:According to the actual landform and geomorphology of the mine, a three-dimensional surface model is established by using DIMINE software, and the blasting design is carried out on the model. Compared with the traditional blasting design, the blasting design based on the model increases visualization, the blasting process can be simulated, and the design delay is more accurate. The limitation of the traditional blasting design in visualization, simulation, analysis and optimization is solved, and the security of the design is enhanced.
