Background technique

Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines, etc. Mine size (also called production capacity) is usually expressed in annual or daily production. Annual production is the amount of ore produced by a mine each year. According to the size of the output, it is divided into three types: large, medium and small. The size of the mine should be adapted to the economical and reasonable service life of the mine. Only in this way can we save the cost of infrastructure and reduce costs. In the process of mine production, mining operations consume the most manpower and material resources, occupy the most capital, and are the production link with the greatest potential to reduce mining costs.
