The dust on mine road surfaces endangers the health of workers, causing mechanical damage to equipment, and polluting the environment. Existing dust inhibitors have low dust suppression efficiency, weak persistence, are expensive. In this study, an environmentally friendly and efficient compound chemical dust suppressant for transportation road dust in a copper mine was developed. On the basis of testing the physical and chemical properties of the dust samples, the best ratio of dust inhibitor was determined using an orthogonal experiment with sodium polyacrylate, sodium carbonate, polyethylene glycol, and alkyl polyglycoside as raw materials, and using anti‐evaporation, hygroscopicity, permeability, pH, and viscosity as the evaluation indexes. Scanning electron micrograph (SEM) and dust removal simulation experiments were conducted. The results show that the optimum formulation of the dust suppressor is 0.08% sodium polyacrylate, 15% sodium carbonate, 2% polyethylene glycol, and 0.15% alkyl glycoside. The SEM experimental results show that the dust samples sprayed with dust suppressor form a network structure from a microcosmic perspective that is conducive to dust suppression. The dust removal efficiency of the whole dust in the laboratory was 96.89% and that of the respirable dust was 86.24%, which proves that the dust suppressor has a good dedusting effect.

铜矿路面抑尘环保复合药剂的制备与表征

矿山路面上的灰尘会危害工人的健康，对设备造成机械损坏，并污染环境。现有的粉尘抑制剂粉尘抑制效率低，持久性弱，价格昂贵。在这项研究中，开发了一种环保，高效的复合化学粉尘抑制剂，用于在铜矿中运输道​​路扬尘。在测试粉尘样品的物理和化学特性的基础上，采用聚丙烯酸钠，碳酸钠，聚乙二醇和烷基多糖苷为原料的正交试验，并采用防蒸发技术，确定了最佳的粉尘抑制剂比例。吸湿性，渗透性，pH和粘度作为评价指标。进行了扫描电子显微镜（SEM）和除尘模拟实验。结果表明，该抑尘剂的最佳配方为0.08％聚丙烯酸钠，15％碳酸钠，2％聚乙二醇和0.15％烷基糖苷。SEM实验结果表明，从抑尘剂的角度出发，喷洒抑尘剂的尘埃样品形成了网状结构，有利于抑尘。实验室中全部粉尘的除尘效率为96.89％，可吸入粉尘的除尘效率为86.24％，证明抑尘器具有良好的除尘效果。SEM实验结果表明，从抑尘剂的角度出发，喷洒抑尘剂的尘埃样品形成了网状结构，有利于抑尘。实验室中全部粉尘的除尘效率为96.89％，可吸入粉尘的除尘效率为86.24％，证明抑尘器具有良好的除尘效果。SEM实验结果表明，从抑尘剂的角度出发，喷洒抑尘剂的尘埃样品形成了网状结构，有利于抑尘。实验室中全部粉尘的除尘效率为96.89％，可吸入粉尘的除尘效率为86.24％，证明抑尘器具有良好的除尘效果。
