While specialized services continue to be developed in the mining industry, there has been a lack of corresponding risk management research in China. This study develops a risk assessment index framework of general contract for mine production and operational specialized service. From previous research, the risk factors for specialized mine production and operation services are identified and the index framework is set up. An index weight is established using Delphi and set-valued statistics-triangular fuzzy number method, and a fuzzy comprehensive evaluation method is applied to assess the mine production and operation risks. With the Jinjie Coal Mine of the Shendong Coal Group selected as a test case, this shows that safety risk, environmental risk, and economic risk belong to level II. Management risk, resources risk, contract risk, and technological risk belong to level I, and the total risk of Jinjie coal mine belongs to level II. The results of the case study indicated that the proposed prevention and control strategies offered a better guide for the risk management practices for the specialized services at Shendong Coal Group.
