Accident data obtained from the Mine Safety and Health Administration (MSHA) were analyzed by the U.S. Bureau of Mines to determine the most frequent causes of blasting accidents in U.S. Mining and to examine trends in blasting accidents. This accident analysis is an update of a similar blasting accident study conducted by the Bureau and publishedin 1983. The analysis shows that there has been a recent reduction in mine blasting accidents. The annual average number of non-fatal injuries has decreased from 107 for 1978- 81 to 46 for 1982-85. The annual average number of fatal injuries was reduced from 11.3 to 5.0 During that time. The largest decrease in blasting accidents occurred in underground mining, where both coal and metal-nonmetal showed declines. There was also a slight decline in accidents in surface mining. In terms of severity rate (average number of lost work days per injury), blasting accidents remain one of the most serious types of accidents in mining. Failure of the blast area security system is the most common cause of blasting accidents. Emphasis should be placed on clearing and guarding of blast areas and on having miners retreat to safe locations during production blasting. Other common causes include premature blasts, excessive flyrock, fumes, and misfires. Trends in blasting accident causes are discussed in this report.
