FACTS: Academy for Mine Training and Energy Technologies
SURFACE EQUIPMENT SIMULATOR TRAINING Southern uses a first-class, state of the art, 3D simulator with a full-range motion based operator's seat, to provide training for surface mine equipment. This simulator is equivalent to those used by the military and commercial airlines for pilot training and can be used for many equipment scenarios.
Administrative Controls for Reducing Workers Noise Exposures
underground and surface coal mines and in coal preparation plants. The surveys revealed numerous possible administrative controls and an approach to implementation and analysis. The surveys have shown that worker dosimetry, time-motion studies and equipment noise profiling are important aspects of effectively utilizing administrative controls.

Assessment of ease of excavation of surface mines ...
During 1987 and 1988 several Canadian surface mines were visited or contacted in an attempt to derive data on equipment and geological and mining environments. Resulting from the survey of prior work, field observations and rock mechanics principles, a new classification system was developed, ( Table 2 and 3 Table 3 ).
