Open-pit Mining VS Underground Mining


Mining is divided into open-pit mining and underground mining. In my country's barite mining, the township and village enterprise mining method accounts for the vast majority. Open-pit mining is the main method, mainly mining residual slope deposits, and outcrops and shallow parts of the ore body.

The open-pit mine was also unable to keep up with the stripping, mining and slope instability, which affected normal production.

Underground mining adopts over-retaining method, filling method, stage caving method, etc. The main mining equipment in underground mining is a hand-push rubber wheeled vehicle, a 300kW winch for inclined shafts, a local fan for ventilation, and wood and concrete supports for underground support. The main equipment for open pit mining is loaders and 4t dump trucks.
