With an increase in the overall slope height of open pit mines, stability analysis and amount of stripping waste rock becomes progressively difficult. It is necessary to optimize the overall slope angle by increasing it as much as possible with ensuring the mining safety. After comprehensive geotechnical investigation and rock mechanical laboratory tests, the combined use of limit equilibrium and numerical modeling analysis methods increases reliability and accuracy of the stability analysis. With the optimum slope design in Bizmisen iron ore mine, there will be a significant decrease in production cost and in the amount of stripping.
