The six special economic zones in Guizhou Province are rich in mineral resources and have proven reserves of 2.58 billion tons of coal. The degree of metamorphism of coal in the area is located between Qianxi Coking Coal Area and the anthracite zone. The coal grades are coke, fat, gas, lean, lean and anthracite, mainly coking coal. The proportions of reserves of each coal grade are as follows: 51.6% of coking coal, 19.4% of fat coal, 1.2% of gas coal, 12.9% of lean coal, 14.7% of lean coal and 0.2% of anthracite. In addition, there are gypsum, lead, zinc, limestone and other mineral resources. Six wells, four fields, large-scale use, chemical office, Mogang and other mines, which are built and put into operation by Liuzhi Mining Administration, have a potential reserves of 380 million tons of geological reserves for development and utilization and an additional 2.2 billion tons of reserves. Coal mine development. Among 51 townships in the region, 43 townships have coal seams exposed. Zhongzhai mayor
