arise from such risk factors as frequent or heavy lifting; pushing or pulling heavy objects; prolonged awkward postures; vibrations; and repetitive, forceful, or prolonged exertion of the hands. Examples of MSDs include low back pain, tendonitis, and carpal tunnel syndrome (NIOSH Facts, http://www.cdc.go/niosh/muskdsfs.html)

Given that wrist, back, and knee injuries show up prominently in mining injury data, the work-related risk factors for these injuries need to be identified to reduce or eliminate them. STRATEgIC gOALS AND OBjECTIvES The reduction of repetitive or cumulative musculoskeletal injuries in mine workers as one of the Mining Program's major strategic goals.

The Mining Program has also formed a partnership with a coal company to enhance the introduction of a process to reduce WMSD risk factors. Research on the reduction of cumulative musculoskeletal disorders is allocated approximately $2.0 million of total annual funding with discretionary funding of about $150,000.

Two lines of research can be seen in the cumulative injury program: the adaptation of off-the-shelf items for mining industry applications; and research on understanding the physiological and biomechanical aspects of mining work. Two major research activities of the last decade included improved seat design for shuttle cars in underground coal mines and a collaborative effort with a sur face coal mining company for implementation of a process to reduce exposure to WMSD risk factors.

Approximately 20 percent of these publications are related to risk factor case studies regarding machines associated with underground and surface mining unit operations and mines in general. Approximately 15 percent of outputs are associated with studies concerning biomechanics and body extremities.

Risks being studied at underground mine include appendage-mining machine working faces contact, stresses to the back associated with various kneeling and standing postures, and the effect of repetitive and forceful motions associated with equipment in motion. The study includes physical and computer modeling, motion analysis techniques, and operator task analysis 4.

REvIEW OF INTERMEDIATE OUTCOMES AND CAUSAL IMPACT As a result of research within the Mining Program, there are a number of find ings with regard to WMSD risk factors in the mining industry. NIOSH investigators note that miners spend a lot of time at work on their knees or in awkward, squat ting positions, spawning a number of studies on knee injuries and the development of effective prevention strategies.

It would be useful to collect and analyze injury experience data directly related to WMSDs on specific operations and tasks in order to develop a stronger association with specific interventions. A number of quantitative indicators attest to the adoption of NIOSH-designed shuttle car seats by manufacturers and mining companies.

From page 130... ...
Since there is similarity in mining, civil engineering, and agricul tural equipment, it would appear that there is a broader scope for the definition of WMSD issues and solutions through more rigorous and formal interactions between various NIOSH research programs and the MSD health effects group.
