The invention belongs to the technical field of power grid enterprise engineering, particularly relates to a power grid big data association mining result full-life-cycle mining method, and particularly relates to an association mining result full-life-cycle management method and system based on big data to realize power grid association mining and data analysis and management. The method comprises the following steps of: formulating a life cycle evaluation criterion; formulating a life cycle operation authority; evaluating the life cycle; mining according to the affiliated stages. According to the invention, the life cycle can be divided for the associated mining theme and the associated mining theme library corresponding to the life cycle is established according to the life cycle; According to the method, the associated mining result is managed according to the life cycle, so that the power grid big data result full-life-cycle management level is improved, the purpose of monitoringthe associated mining result full cycle is achieved, and power grid big data associated mining closed-loop management can be effectively promoted.
