AI Technical Summary
Existing technologies in deep mining of metal mines have poor ventilation effects due to localized fans, low air intake, poor cooling effect, and high maintenance and management costs, making it difficult to meet the ventilation requirements of deep, high-temperature and high-humidity environments.
The natural ventilation structure is adopted, which connects the external roadway, the connecting roadway of the stope, the internal roadway of the stope and the return air shaft, reducing the use of local fans. The ventilation system is constructed by using ventilation pipes and branch pipes to directly exhaust the dust and blasting fumes from the working face to the return air system, thereby reducing energy consumption and maintenance costs.
It achieves efficient ventilation, ensuring that the intake is filled with fresh air, significantly improving air quality, reducing energy consumption and maintenance costs, avoiding fan overheating and space occupation issues, and improving the safety and equipment efficiency of deep mining.
