An analysis of surface haulage accidents occurring in the United States mining industry was performed. The database of the Mine Safety and Health Administration was searched to identify all accidents involving haulage trucks, both off highway and underground, between 1986 and 1995. Accidents classified as occurring underground or to office workers were excluded. The details of each accident were reviewed. Surface accidents in mining that caused fatalities, including those involving haulage trucks, had decreased since 1986 with a minimum of 54 deaths in 1994. In 1995 there were 70 fatalities. There was an increase in the number of haulage truck deaths, increased from ten in 1994 to 17. Lost time haulage truck accidents decreased from 579 in 1994 to 460 in 1995, reflecting an overall decrease in the number of surface accidents (from 9,040 to 7,883). Fatal haulage truck accidents in 1994 cost an estimated 2.58 million dollars. The lost time injuries cost an estimated 3.27 million dollars. Independent contractors accounted for 18 to 67% of the haulage truck fatalities and 4 to 13% of the lost time injuries over the study period. Multiple injuries (64 deaths) and crushing (34 deaths) were the two major types of fatal haulage truck accidents. Sprains and strains were the major type of lost time injury with 2,437 injuries reported. Lost time injuries most frequently involved the back (1,511 injuries) or multiple body parts (659 injuries). The two major causes of fatal haulage accidents were associated with operating the truck (61 deaths) and performing maintenance work (12 deaths). The three main causes of loss time injury were operating the truck (2,447 injuries), getting on and off equipment (1,480 injuries), and performing maintenance (547 injuries). Fatal surface haulage accident rates did not vary significantly with mine size, range 0.0349 to 0.0357 accidents/200,000 employee hours. The highest rates of lost time injuries, 4.12 to 4.13 accidents/200,000 hours, occurred in medium sized mines (employing 11 to 50 miners).
