Huainan Coal Mine was established in 1897 and has a mining history of more than 120 years. It was once one of the five major coal mines in China. Since the founding of the People's Republic of China, it has made great contributions to ensuring energy security in East China and is known as the "Coal Capital of East China" and "Hometown of Power". In March 1998, Huainan Mining Group was restructured from Huainan Mining Bureau, and in July of the same year, it was transferred from the former Ministry of Coal to Anhui Province for management. In May 2018, due to the overall restructuring and listing needs of the enterprise, Huaihe Energy Holdings Group was officially established with the approval of the Anhui Provincial Party Committee and Government. In October of the same year, it became the controlling shareholder of Huainan Mining Group.
