对湖南湘永煤矿井下工人回顾性调查资料的分析表明,该矿26年(1960～1985年)尘肺防制取得明显的经济效益和社会效益,共减少304例尘肺的发生,获得经济效益约2997.62万元,除去26年用于尘肺防制投资的总费用,所得纯经济效益870.23万元。由于受到观察时间的限制及其它原因,使总的效益估计偏低。认为进行尘肺防制早期需付出大量费用,却可获得长远效益,比发生了尘肺病人把钱用在医疗费用和抚恤费上要经济有效。
An analysis of retrospective survey data of coal mine workers in Hunan Xiang Yong shows that significant economic and social benefits have been achieved in the control of pneumoconiosis for 26 years (from 1960 to 1985) in the mine, with a total reduction of 304 cases of pneumoconiosis, with an economic benefit of about 2997.62 Million, excluding 26 years for the total cost of pneumoconiosis prevention and control of the investment, the resulting net economic benefits 8.7223 million yuan. Due to the limitation of observation time and other reasons, the overall benefit estimate is low. In the early days, it was considered costly for pneumoconiosis to be costly in the long run, but long-term benefits could be obtained. It was more cost-effective than using pneumoconiosis patients to spend money on medical expenses and pensions.
