[0002] Mines include coal mines, metal mines, non-metallic mines, building materials mines, and chemical mines, among others. Mine scale (also known as production capacity) is typically expressed in terms of annual or daily output. Annual output refers to the amount of ore a mine produces each year. Based on the size of the output, mines are categorized into three types: large, medium, and small. The size of a mine must be consistent with its economically reasonable service life. Only in this way can capital construction costs be saved and costs reduced. In the mining process, mining operations consume the most manpower, material resources, and capital, yet they also represent the production link with the greatest potential for reducing mining costs. The primary way to reduce mining costs is to improve labor productivity and product quality and reduce material consumption.
