Background

During 2011, a study was undertaken to assess safety conditions in Serbian underground coalmines by analysis of injury data. The study covered all Serbian coalmines, identified week spots from the aspect of safety, and recommended possible courses of action. Since then, Serbia has made changes to safety and health legislation; all coalmines introduced new preventive measures, adopted international standards, and made procedures for risk management. After 10 years a new study has been performed to analyze the impact of these changes.

Materials and methods

In this study, the injuries that have occurred in the Serbian underground coal mines over the last 20 years were analyzed. Statistical data analysis was performed by IBM SPSS Statistics v23. The injuries that occurred in the last ten years were compared with the results of the previous study (2000–2009). The average values of injury rates for both periods were compared for each of the categories (severity, age, body part, qualification), and the results were presented as absolute difference or percentile difference.

Results

The results showed reduction in the number of injuries in the category of 20–30 years old workers, where the new training procedures for workers, which were set by mandatory legal regulations, certainly contributed. They also showed an increase in the number of injuries in the category of old workers, which indicates that the law did not have a positive effect on this category.

Conclusion

The total number of injuries is still high; therefore, it is necessary to introduce mechanization and automation in mines and have a better policy for older workers who retire later nowadays.

塞尔维亚地下煤矿伤害的回顾性比较研究

背景

2011 年，开展了一项研究，通过分析伤害数据来评估塞尔维亚地下煤矿的安全状况。该研究涵盖了所有塞尔维亚煤矿，从安全方面确定了周点，并推荐了可能的行动方案。从那时起，塞尔维亚对安全和健康立法进行了修改；各煤矿采取了新的防范措施，采用了国际标准，制定了风险管理程序。10 年后，一项新的研究进行了分析这些变化的影响。

材料和方法

在这项研究中，分析了过去 20 年来在塞尔维亚地下煤矿中发生的伤害。统计数据分析由 IBM SPSS Statistics v23 执行。将过去十年中发生的伤害与先前研究（2000-2009 年）的结果进行了比较。比较每个类别（严重程度、年龄、身体部位、资格）的两个时期的伤害率平均值，结果以绝对差异或百分位差异表示。

结果

结果显示，20 至 30 岁工人类别的受伤人数减少，强制性法律规定为工人制定的新培训程序肯定有所贡献。他们还显示，老年工人类别的受伤人数有所增加，这表明法律对该类别没有积极影响。

结论

受伤总数仍然很高；因此，有必要在矿山引入机械化和自动化，并为现在较晚退休的老年工人制定更好的政策。
