Abstract: The rock quality in Jinfeng Gold Mine is overall poor,classified from extremely bad to medium.In light of the problems in the approach mining,such as the intense workload of roadway excavation,and poor excavation efficiency and quality,the excavation drilling blasting parameters are optimized,to obtain a good blasting index and improve drilling efficiency.By carrying out an experimental study on approach excavation drilling blasting parameters optimization in Jinfeng Gold Mine,the number of boreholes is reduced,and the drilling efficiency is improved.Reasonable borehole parameters layout and charge completely solve the blasting problems,and at the same time regulate over and under break,mitigate mining loss and dilution.The roadway forms well and the approach footage is great,living up to expectations.
