Purpose

To investigate the effect of a task rotation schedule on musculoskeletal injury and the challenges of implementing a task rotation schedule within an underground coal mine.

Methods

This was a pre-post cross-sectional intervention study with two underground coal mines. Participant-surveys were collected at baseline and 12-months.

Results

There were no significant differences in musculoskeletal discomfort between the two sites in any body region. Tasks were rotated two to three times a shift on average.

Conclusions

The task rotation schedule did not have a significant impact upon musculoskeletal discomfort although this does not necessarily reflect that the rotation schedule was in-effective in curbing injury, rather highlights the complexity of developing a successful task rotation schedule within an underground coal mine. The task rotation schedule, its implementation and execution need consideration and further investigation to assist in effectively controlling injury and fatigue risk.

地下煤矿的任务轮换:对受伤和肌肉骨骼不适的影响

目的

调查任务轮换计划对肌肉骨骼损伤的影响以及在地下煤矿内实施任务轮换计划的挑战。

方法

这是一项对两个地下煤矿进行的前后横断面干预研究。在基线和 12 个月时收集参与者调查。

结果

在任何身体区域的两个部位之间的肌肉骨骼不适没有显着差异。任务平均每班轮换两到三次。

结论

任务轮换计划对肌肉骨骼不适没有显着影响,尽管这并不一定反映轮换计划在抑制伤害方面无效,而是突出了在地下煤矿内制定成功的任务轮换计划的复杂性。任务轮换计划及其实施和执行需要考虑和进一步调查,以帮助有效控制伤害和疲劳风险。
