Taking Qidashan open-pit stope as the research object, field investigations were carried out. Fixed-point and vehicle-mounted mobile continuous monitoring was conducted during the drilling, blasting, loading and transportation stages, with meteorological parameters recorded and the dust migration process photographed. Based on the field monitoring data, an analysis was conducted on the dust dispersion characteristics and influence mechanism in different stages during the production process of the open-pit mine. The results show that there is a significant correlation between PM_2.5 and PM₁₀ concentrations. The cubic polynomial curve model has the highest goodness of fit, with a coefficient of determination of 0.945, and exhibits the strongest explanatory power for this relationship. The average dust emission concentrations and diffusion ranges differ significantly among different production stages. The blasting stage has the highest dust emission concentration in a single operation, reaching 324.4 μg/m³, and its dust diffusion range is the widest. The dust emission concentrations of a single operation in the drilling, loading and transportation stages are 59.8 μg/m³, 88.2 μg/m³ and 61.8 μg/m³, respectively. In addition, the dust concentration in the pit bottom area is significantly higher than that at the bench crest, with its mean value being approximately five times that of the dust concentration at the bench crest. The research results reveal the variation laws of dust concentration in open-pit stopes and can provide theoretical support for dust prevention and control.

以齐大山露天采场为研究对象，通过实地勘查，在穿孔、爆破、采装、运输环节进行固定点位与车载移动连续监测，记录气象参数并拍摄粉尘运移过程。基于现场监测数据，对露天矿山生产过程中不同环节的粉尘弥散特征与影响机制进行分析。结果表明：PM_2.5与PM₁₀浓度存在显著的相关关系，三次项曲线模型的拟合优度最高，决定系数为0.945，对关系的解释能力最强；不同生产环节的产尘浓度平均值及扩散范围差异明显，爆破环节单次作业产尘浓度最高，达324.4 μg/m³，且粉尘扩散范围最广；穿孔、采装和运输环节的单次作业产尘浓度分别为59.8 μg/m³、88.2 μg/m³和61.8 μg/m³；此外，坑底区域的粉尘浓度显著高于闭合圈，其浓度均值约为闭合圈粉尘浓度均值的5倍。研究成果揭示了露天采场粉尘浓度的变化规律，可为粉尘防控提供理论支持。
