Numerical simulation analysis of high bench blasting charge structure in Open-pit Coal Mine
HOU Chengheng
Abstract：In order to optimize the high bench blasting charge structure in open-pit coal mine, the article investigates the existing high bench blasting charge structure. Combining with the geological characteristics, rock mass structure, physical and mechanical properties of rock and loading equipment, the author analyzes the different schemes. According to the theoretical analysis results, the mine uses ANSYS/LS-DYNA software to carry out blasting numerical simulation. The results show that the high bench blasting with air interval charge is better than continuous charge , which obtains higher economic benefits.
