Reduction of risk of occupational injuries is one of the most challenging problems faced by industry. Assessing and comparing risks involved in different jobs is one of the important steps towards reducing injury risk. In this study, a comprehensive scheme is given for assessing and comparing injury risks with the development of injury count model, injury risk model and derived statistics. The hazards present in a work system and the nature of the job carried out by workers are perceived as important drivers of injury potential of a work system. A loglinear model is used to quantify injury counts and the event-tree approach with joint, marginal and conditional probabilities is used to quantify injury risk. A case study was carried out in an underground coal mine. Finally a number of indices are proposed for the case study mine to capture risk of injury in different jobs. The findings of this study will help in designing injury intervention strategies for the mine studied. The job-wise risk profiles will be used to prioritise the jobs for redesign. The absolute indices can be applied for benchmarking job-wise risks and the relative indices can be used for comparing job-wise risks across work systems.
降低职业伤害风险是工业界面临的最具挑战性的问题之一。评估和比较不同工作中的风险是降低伤害风险的重要步骤之一。在这项研究中，提出了一种综合的评估和比较伤害风险的方案，通过伤害计数模型、伤害风险模型和衍生统计的开发来实现。工作系统中存在的危险以及工人从事的工作性质被视为工作系统伤害潜力的重要驱动因素。对数线性模型用于量化伤害计数，事件树方法结合联合、边际和条件概率用于量化伤害风险。在一个地下煤矿进行了案例研究。最后，为案例研究煤矿提出了一些指标，以捕捉不同工作中的伤害风险。这项研究的结果将有助于为研究中的煤矿设计伤害干预策略。按工作划分的风险概况将用于为重新设计确定工作优先级。绝对指标可用于基准测试工作风险，相对指标可用于比较不同工作系统中的工作风险。
