title: The health benefits of mechanization at the Nigerian Coal Corporation.
abstract: Nigerian Coal Corporation started operations in 1916 and in October 1977 introduced full mechanization at its coal mine in Enugu. An appraisal of the mining accidents between 1975-1980 showed an overall downward trend following mechanization, from 1073 per 1000 in 1975 to 425 in 1980 (a 60% reduction). The underground accidents were reduced from a monthly average of 63 to 26 but those at the surface remained basically unaffected. Changes were also recorded in sickness absences indices, with the most significant occurring with respect to the severity index which dropped from 9.2 in 1975 to 3.0 in 1980. The distribution of injury remained essentially the same except that injuries to the upper limbs became more common than the more serious pelvic injury prior to mechanization. The impact of mechanization in industries in developing countries are discussed and ways of ensuring optimum benefits from this transfer of technology suggested.
