Proposed Project

Postural Analysis in Low-Seam Mines—New—National Institute for Occupational Safety and Health (NIOSH), Centers for Disease Control and Prevention (CDC).

Background and Brief Description

NIOSH, under Public Law 91-596, sections 20 and 22 (section 20-22, Occupational Safety and Health Act of 1970) has the responsibility to conduct research relating to innovative methods, techniques, and approaches dealing with occupational safety and health problems.

According to the Mining Safety and Health Administration (MSHA) injury database, 227 knee injuries were reported in underground coal mining in 2007. With data from the National Institute for Occupational Safety and Health (NIOSH), it can be estimated that the financial burden of knee injuries was nearly three million dollars in 2007.

Typically, mine workers utilize kneepads to better distribute the pressures at the knee. The effectiveness of these kneepads is to be investigated in a study by NIOSH. Thus, NIOSH will be determining the forces, stresses, and moments at the knee while in postures associated with low-seam mining. At this time, the postures utilized by low-seam mine workers and their frequency of use are unknown. Therefore, before conducting this larger, experimental study, the proposed field study must be conducted.

The aim of the proposed field study is to determine the postures predominantly used by low-seam mine workers such that they may complete the various tasks associated with their job duties. A questionnaire was developed for each of the major job types seen in low-seam mines with continuous miners (continuous miner operator, roof bolter operator, shuttle car operator, mobile bridge operator, mechanic, beltman, maintenance shift worker, foreman). The questionnaire asks basic demographic information (e.g., time in job type, years in mining, age). Additionally, a series of questions are asked such that it may be determined if a mine worker is likely to have a knee injury, even if it is undiagnosed. These questions were developed with the help of a physical therapist. A schematic of possible postures will then be presented to the mine workers and they will be asked to identify the primary two postures they utilize to complete their job duties. The questionnaire then asks mine workers to identify the primary postures they utilize to complete specific tasks (e.g., hanging curtain, building stoppings) that are part of their job duties. Finally, mine workers are asked to identify those postures that are least and most comfortable/stressful. There is no cost to respondents other than their time.Start Printed Page 30097
