Dahaize Coal Mine Project is a supporting resource mine for the coal chemical project of China Coal Shaanxi Yulin Energy and Chemical Co., Ltd., and it is an important support for China Coal Group to build a 100 million tons coal base in Mengshan. The project is located in the west of Yuyang District, Yulin City, Shaanxi Province. The administrative division is under the jurisdiction of Yuyang District, bordering Inner Mongolia Autonomous Region in the west and 40 kilometers away from Yuheng Coal Chemical Industry Park.
The geological structure of the mine field is simple, the roof and floor are stable, the gas content is low, the mining conditions are superior and the coal seam occurrence is stable. The main minable coal seams are No.2, No.3 and No.4-2 coal seams, in which the average thickness of No.2 coal seam is about 6 meters. The average thickness of No.3 coal seam is about 4 meters, and the average thickness of No.4-2 coal seam is about 2 meters. The coal quality of the mine field is excellent, with the characteristics of ultra-low ash, medium-low sulfur and ultra-high calorific value, and it is a high-quality coal for chemical industry and electric power.
The mine construction scale is 20 million tons/year, and the service life is about 1 14 years. Four vertical shafts are used for development, and one well is arranged on each side. The project is expected to be put into production in 2022. After it is put into production, it will provide strategic guarantee for the construction of energy and chemical base in northern Shaanxi of China Coal Group and the integrated development of coal and electricity of China Coal Shaanxi Company, and will also play a significant role in promoting local economy and local development.
