This paper introduces the application of analytic hierarchial procee (AHP) method in the injury assessment of abandoned mining shafts, and systematically explains assessment method and model by using of AHP method, providing scientific basis for harnessing of abandoned mining shafts, and prevention and reduction of disasters. Taking the abandoned mining shafts in Jiangxi Province as an example, the paper briefly describes the current situation of abandoned mining shafts in Jiangxi Province, and analyses the origin of injury. Choosing the types, resident populations in the peripheral area of 1 km², wellhead stable states and within-well safety factors of abandoned mining shafts as 4 assessment indexes, a division of injury assessment indexes and injury grades is made by using of hierarchical weighted calculation and injury grades of abandoned mining shafts in the whole Province are assessed, being helpful for decision of all-round arrangement and advance for the harnessing of hidden safety dangers.
