Sichuan Weiyuan Coal Mine was built in 1940, and the late former CPPCC member Sun was the first mine manager. From the early days of liberation to the Third Five-Year Plan period, it was one of the important coal bases in Sichuan Province, with a maximum annual output of 990,000 tons. Sichuan Coal Industry Group, a provincial key state-owned coal mine, is a wholly state-owned enterprise, headquartered in Huangjinggou Town, Weiyuan County, Neijiang City. The enterprise originally had five pairs of production mines. Since the end of 1970s, due to the gradual depletion of resources, mines have shrunk into a pair of mines, and enterprises began to lose money. Since the 1990s, with the strong support of the state and governments at all levels, Sichuan Rongxing Chemical Co., Ltd. and Sichuan Xuyong Coal Mine have been put into production successively in 2000 through the efforts of 10 years, and Weixin Coal Mine will also complete the infrastructure work in June 2009. So far, Sichuan Weiyuan Coal Mine has developed into a medium-sized energy and chemical enterprise, which is composed of Weiyuan Coal Mine, Rongxing Company, Xuyong Coal Mine and Weixin Coal Industry and spans four cities, five districts and counties. The main products are anthracite, bituminous coal, sodium sulfate, mining machinery, power generation, clean coal and so on. The company has 365,438+065,438+065,438+0 employees, annual sales income of 65.438+0.2 billion yuan and total assets of 26.5438+0.0 billion yuan.
