This paper, aiming at the dangerous aspects and potential accidents in coal-bed methane drilling projects, establishes a risk assessment system. The FAHP has been applied to assess the risks in coal-bed methane drilling project. The risk index system is defined through drilling projects, and assigned with weights by means of AHP. The risks are classified as key risks and common risks via the ABC classification method in economics. This method has been used to calculate the risk value in Sihe coal-bed methane drilling project, Jincheng, Shanxi province. The value is 4.1, meaning of big risk.
