| Abstract: |
| An underground gold mine has entered the mining stage. To reduce the cost of drilling, blasting and shovel loading in the mining process, it is necessary to optimize the blasting fragmentation gradation, and obtain a more reasonable blasting fragmentation of upward fan-shaped blast holes to optimize the blasting parameters. The blasting piles of different mining areas under blasting mining in an underground gold mine were photographed, and the cost data such as the number of boreholes, explosive dosage, and shovel transportation link under the corresponding blasting parameters were collected, and use the Split-Desktop4.0 software, get the relationship formula between drilling and blasting, shovel loading cost and average block size in different mining areas, and establish the cost model. Results: The cost model results show that the economic and reasonable blasting fragmentation interval of an underground gold mine based on drilling, blasting and shovel loading is 21～24 cm, and the corresponding main blasting parameters are: hole bottom spacing is about 1.9 m, row spacing is about 1.5 m, and hole depth is 5～14 m. It saves the production cost of the mine, improves the production efficiency, and supplements the theoretical basis for relevant research. Innovation: Apply the computer blasting fragmentation analysis software to the optimization of mine production cost, and take this as the starting point to explore the corresponding reasonable blasting parameters, so as to provide new ideas for relevant research. |
