Surfactant-enhanced water spray technology, one of the most economical and efficient dust suppression technologies, is widely used for dust control in mining. Unfortunately, current research on this technology appears to be scattered, and the results do not provide an effective approach for coal dust control. Aimed at addressing this problem by critically reviewing coal dust agglomeration mechanisms and dust suppression effectiveness, this review summarized four steps for droplets capturing coal dust, and two agglomeration mechanisms(immersion and distribution mechanisms) are illustrated based on them. In addition, the dust suppression effect is categorized as either indirect dust suppression or direct dust suppression, depending on the coal dust removal effect. The suppression results show that surfactants can significantly improve the indirect dust suppression, the direct dust suppression efficiency of surfactant-enhanced water spray technology is generally between 80 % and 95 % and can be increased by approximately 40 % compared to the conventional spray dust reduction efficiency, and the suppression efficiency for respirable coal dust (below PM10) is approximately 1 % lower than that of total dust. In the discussion on the challenges and further research directions, relative motion and capture of fine particles, effect evaluation methods and standard, relationship between direct and indirect dust suppression effects, as well as field application technology, are suggested as the main challenges and directions for improving the efficiency of this technology.

表面活性剂增强喷水技术是最经济、最有效的抑尘技术之一，广泛应用于矿山粉尘治理。不幸的是，目前对这项技术的研究似乎很分散，结果没有为煤尘控制提供有效的方法。针对这一问题，本文通过对煤尘团聚机制和抑尘效果的批判性综述，总结了液滴捕获煤尘的四个步骤，并在此基础上阐述了两种团聚机制（浸入和分布机制）。此外，抑尘效果根据煤的除尘效果分为间接抑尘和直接抑尘。抑尘结果表明，表面活性剂能显着提高间接抑尘效果，表面活性剂增强喷水技术的直接抑尘效率一般在80%~95%之间，较常规喷雾降尘效率可提高约40%。 ，对可吸入煤尘（PM10以下）的抑制效率比总粉尘低约1%。在对挑战和进一步研究方向的讨论中，提出了细颗粒物的相对运动和捕获、效果评价方法和标准、直接和间接抑尘效果之间的关系以及现场应用技术作为主要挑战和方向。提高这项技术的效率。表面活性剂增强喷水技术的直接降尘效率一般在80%~95%之间，比常规喷雾降尘效率可提高约40%，对可吸入煤尘（PM10以下）的抑制效率为比总粉尘低约 1%。在对挑战和进一步研究方向的讨论中，提出了细颗粒物的相对运动和捕获、效果评价方法和标准、直接和间接抑尘效果之间的关系以及现场应用技术作为主要挑战和方向。提高这项技术的效率。表面活性剂增强喷水技术的直接降尘效率一般在80%~95%之间，比常规喷雾降尘效率可提高约40%，对可吸入煤尘（PM10以下）的抑制效率为比总粉尘低约 1%。在对挑战和进一步研究方向的讨论中，提出了细颗粒物的相对运动和捕获、效果评价方法和标准、直接和间接抑尘效果之间的关系以及现场应用技术作为主要挑战和方向。提高这项技术的效率。
