|
Modern highwall mining systems are starting to replace surface coal augers in some highwall mining operations because of their ability to increase coal production and recovery rates. Another benefit of using highwall mining systems instead of surface coal augers is the reduction in noise exposures to the affected miners extracting the coal from the highwall. Several surface coal augers and highwall mining systems were evaluated for full shift noise exposures of the machine operator and helpers during this investigation. Engineering noise controls were also evaluated for each piece of highwall mining equipment. The operator and helper working on a modern highwall mining system were exposed to average sound pressure levels of 61.5 and 89.0 dBA, respectively, while the operator and helper working on a surface coal auger were exposed to higher average sound pressure levels of 95.4 and 94.0 dBA, respectively. |
