简介：低煤层煤矿中存在的有限工作空间迫使工人采用笨拙的工作姿势（跪着和弯腰），这对膝盖和下背部提出了很高的身体要求。方法：本文分析了1996-2008年期间八家经营低煤层煤矿的矿业公司的伤害索赔情况。所有成本数据均使用美国劳工统计局提供的医疗保健成本（MPI）数据进行标准化。结果如下：分析结果表明，膝盖是索赔费用最高的身体部位（420万美元），其次是腰部受伤（270万美元）。虽然这些身体部位每次受伤的平均费用分别为13 100美元和14 400美元（接近受伤总费用的平均值），但这些受伤的频率很高，因此在费用方面占首位。对单个矿业公司数据的分析表明，膝盖和下背部受伤是各公司的一个持续问题，因为这些受伤都是八分之七的公司中身体最昂贵的五个部位之一。应用/影响。这项调查的结果表明，努力减少膝盖和腰部受伤的频率在薄煤层矿井有可能创造大量的成本节约。爱思唯尔有限公司出版
Introduction: The restricted workspace present in low-seam coal mines forces workers to adopt awkward working postures (kneeling and stooping), which place high physical demands on the knee and lower back. Method: This article provides an analysis of injury claims for eight mining companies operating low-seam coal mines during calendar years 1996-2008. All cost data were normalized using data on the cost of medical care (MPI) as provided by the U.S. Bureau of Labor Statistics. Results: Results of the analysis indicate that the knee was the body part that led in terms of claim cost ($4.2 million), followed by injuries to the lower back ($2.7 million). While the average cost per injury for these body parts was $13,100 and $14,400, respectively (close to the average cost of an injury overall), the high frequency of these injuries resulted in their pre-eminence in terms of cost. Analysis of data from individual mining companies suggest that knee and lower back injuries were a consistent problem across companies, as these injuries were each among the top five most costly part of body for seven out of eight companies studied. Application/Impact. Results of this investigation suggest that efforts to reduce the frequency of knee and low back injuries in low-seam mines have the potential to create substantial cost savings.
