| Abstract |
The publication reviews the transportation fatalities that occurred in bituminous coal mines during 1956-66. Statistics show that mine transportation accidents accounted for 19 percent of fatalities in these mines, second only to roof deficiencies as a cause of death. Productivity per man-shift increased from 10.2 tons in 1956 to 18.4 tons in 1966, but the fatalities per million man-hours of exposure also increased from 0.19 to 0.21 during that same period, indicating that transportation hazards still persist. The data in this report were processed by computer to find what constitute hazardous conditions and unsafe actions as well as to correlate occupation and age of victims, transportation type, and mine production. Environmental factors and equipment defects which create hazards, as well as unsafe actions of personnel, were determined for each type of mine transportation: Track haulage, mobile nonrail haulage, conveyors, hoists, automotive operations, and front-end loaders. |
