Wujiu Coal (Group) Co., Ltd., located in Urqihan Town, northeast of Yakeshi City, Inner Mongolia Autonomous Region, is named after 59 kilometers away from Yakeshi City. It has a history of coal mining for 65 years, and its predecessor was Wujiu Coal Mine of Hulunbeier League. In 1957, according to the national policy of "replacing wood with coal", the Inner Mongolia Industry Department sent a preparatory group to this area to prepare for mine construction. At the beginning of the mine construction, the production environment was very difficult, and the builders rested in the open air, and completed the production infrastructure construction by backward methods such as shoulder-picking, pick-planing and pulling carts by people.  

From 1967 to 1977, during the Cultural Revolution, the output always hovered around 100,000 tons, even tens of thousands of tons, and the enterprises were always in a state of loss. After the Cultural Revolution in 1978, the output of raw coal increased year by year, safety production facilities were put into use, management gradually improved, and enterprises began to take shape. In 1989, in order to implement the spirit of the Third Plenary Session of the 13th Central Committee and deepen the reform of enterprise economic system, Wujiu Coal Mine implemented the first round contract management responsibility system, with the mine manager as the first responsible person, and the management responsibility was further clarified. In 1994, Wujiu Coal Mine officially entered the market economy from the planned economy and was transformed into a limited liability company. Due to the change of management, the output of raw coal increased from the previous annual output of 200,000 tons to 500,000 tons, thus throwing off the hat of loss. In 2003, a (group) company was established, realizing a new leap in the development history of Wujiu. On December 12, 2006, Sundiro Holding Co., Ltd. took over Wujiu Group in an all-round way by means of asset restructuring, and transformed the local state-owned coal mine into a non-public enterprise. In 2012, 49% equity of Shandong Energy Zaozhuang Mining Group was transferred to management, and Wujiu Group officially opened a new road for the development of mixed ownership enterprises.  

The company now consists of 9 functional departments and 5 secondary units, with more than 2,500 employees. There are two pairs of production mines, with an annual production capacity of 3 million tons and reserves of mining rights of nearly 1.6 billion tons. The main products are long flame coal with low sulfur, low phosphorus, low ash and medium and high calorific value. With total assets of 2 billion yuan, the company paid taxes of 226 million yuan in 2021. It is the pillar enterprise and the largest taxpayer in Yakeshi, and has formed diversified industrial patterns such as coal production and sales, railway transportation, power supply and heating, mechanical and electrical repair, and tertiary trade. As a regional key enterprise, it has won the "National May Day Labor Award", "National Advanced Unit for Enterprise Culture Construction of Coal System" and many honors issued by Inner Mongolia Autonomous Region and Hulunbeier City, and is now a AAA credit rating enterprise in the national coal industry.
