Study on comprehensive health risk assessment of coal mine dust

In view of the seriousness and universality of pneumoconiosis among coal miners and the lack of coal mine dust evaluation, this paper aiming at various factors affecting coal mine dust hazards, starts from the direct factors of dust production, determines five major index systems:objective factors, underground processes, operators, dust prevention measures and monitoring system, and adopts analytic hierarchy process, and establish the model of index weight evaluation, determine the mapping relationship between index and score, divide the risk level into five levels, finally build a set of quantitative evaluation system integrating internal and external factors, and develop supporting software based on computer language.The results show that the scores of the evaluation system in the three groups of coal mines are significantly different, the dust hazard levels in different mines are different, and the classification is consistent with the actual dust status of the mine.The decision support provided by the evaluation system is objective and reasonable.The evaluation system established in this paper is valuable for reference and popularization, accelerates the standardization and scientific evaluation of coal dust, enhances people’s understanding the danger degree of coal mine dust, and promotes coal mine dust prevention and control work.
