Optimization for Central Bridge Transport System of a Surface Mine Under Complicated Geological Conditions

The applicability of the intermediate bridge transportation system is analyzed with complex geological conditions such as anticline and fault. For the needs that internal freight charges are not greater than the dual-ring internal freight charges, we established optimization inequality and gave the corresponding service level model. Taking Anjialing surface mine as an example, the construction level, service level and economic benefits of the intermediate bridge are demonstrated.
