| Abstract: |
| In response to the lack of systematicity in the evaluation of mining value of residual ore resources, this study constructs a comprehensive evaluation system encompassing residual ore information, mining engineering, and risk factors, based on the preliminary stope mining plan. Taking "Operating income-Direct costs-Other costs" as the basic economic model, the system calculates the Risk-Adjusted Gross Profit (RAM) using the Monte Carlo method, realizing risk adjustment and value assessment of the gross profit from residual ore mining. Applied to the residual ore mining in the southern part of the 10th level of an overseas lead-zinc mine, the results demonstrate that the system can comprehensively and accurately reflect the economic value and risk level of residual ore mining. It provides scientific theoretical support and practical guidance for mining enterprises in making residual ore mining decisions. |
