| Abstract: |
| This paper due to eliminate some greatpotential risk for miner and transportation equipment when to multi-sublevel ore-drawing. It could be solved by reconstructing the partial winze and constructing the united way of segmented ore-pass, fork winze and devilling to ensure the safety in the process of ore drawing and meet the production needs. By this project, ore drawing can function well on conditions that the united way of segmented ore-pass needed not pass through the main ore-pass directly. In addition, the application of ramose ore-pass reduced the number of systematic ore-pass, improved the utilization ratio of each ore-pass, guaranteed the safety of workers in the process of ore drawing and equipment, and achieved remarkableeconomic and safety benefit. This approach of ore drawing can provide some reference and guidance for future producing and mining in the same type of ore deposit. |
