摘要: 为了提高煤矿粉尘防治干预措施的干预效能,降低矿工罹患尘肺病风险,以甘肃某煤矿矿工为研究对象,通过改变“可变”因子及矿工受干预后在粉尘防治知识、行为、态度方面的量化评估,研究分析干预模式、干预时间、特征因素在矿工粉尘防治过程中对干预效能的影响变化情况。研究发现:跨理论模型TTM指导的干预方案比常规方案效能提升12%以上,干预时间间隔过长干预效能发生下降,不同年龄、工龄、文化程度阶段的矿工表现出的受干预效果变化也不尽相同;在矿工粉尘防治干预过程中,将“可变”因子与矿工自身特征因素结合而采取的干预方案的干预效能更好。Abstract: In order to improve the intervention effectiveness of coal mine dust prevention intervention measures and reduce the risk of pneumoconiosis among miners, miners of a coal mine in Gansu were taken as the research object. By changing the “variable” factors and the quantitative evaluation of dust prevention knowledge, behaviors and attitudes of miners after intervention, we research and analyze the impact of intervention mode, intervention time, and characteristic factors on the effectiveness of intervention. It was found that the effectiveness of the TTM-guided intervention program was increased by more than 12% compared with the conventional program. The intervention interval time is too long, which leads to a decrease in the effectiveness of the intervention; the intervention effects of miners at different ages, working ages, and education levels also vary. Research shows that in the intervention process of miner dust prevention and control, an intervention scheme that combines “variable” factors with the characteristics of the miner’s own characteristics has better intervention effectiveness.
