| Abstract: |
| The ventilation system of Gacun Silver Polymetallic Mine belongs to the type of high-altitude mountain mining. Based on the investigation and measurement of the present mine ventilation system, this paper analyzed the existing problems of the ventilation system, put forward two feasible renovation schemes for the ventilation system at high altitude mine, compared the schemes from the technical and economic point of view, and optimized the best scheme, namely, forced-exhaust diagonal ventilation scheme preheating by ground temperature with central intake and two wings return. It can provide a reference for similar ventilation systems at high altitude mines. |
