2. Mining-processing industrial and mining areas, the employees of extractive industries account for 50%-70% of the employees of industrial and mining industries, mining areas are dominated by extractive industries, and processing industrial areas account for a certain proportion;
3. In the processing and mining industrial and mining areas, the number of employees in the mining industry is below 50%, and the processing industry has risen from secondary to main position, generally in the old coal mining areas with better development conditions of processing industry and some metal mining areas with metallurgical industry as the main industry.
