Accident prediction investigation study (Mod 1A).
Spokane, WA: U.S. Department of the Interior, Bureau of Mines, Contract S0122023, 1972 Sep; :1-174
The objective of this study was to investigate promising accident factors that historically have not been reported to the Bureau of Mines on nonfatal injury accidents. The contractor analyzed existing accident report data for a specific mining area. Each factor was evaluated in terms of its data availability for analysis, its importance, and potential accident predictive value. The contractor developed some significant information concerning accident occurrence, particularly regarding the factors of task experience and job mobility of workers. The study determined that there is a lack of reliable accident prediction potential for all factors tested and an extremely high variance in accident rates both in type and characteristic in the mines studied. The study indicated a considerable amount of randomness in accident occurrence. It also confirmed that much of the basic accident data required for a predictive model is not presently available.
