Red sand dust pollution is of great concern for its occupational and environmental detriments. The current remediation technique includes water spray and non-traditional stabilization via the application of polymer stabilizers. The dust erosion resistance plays a significant role in quantifying the effectiveness of red sand dust suppression. The aim of this paper is to evaluate the reliability and accuracy of five static and dynamic laboratorial methods that are commonly utilized to quantify the dust erosion resistance in the presence of polymers in previous studies, which are wind tunnel simulation, dynamic viscosity test, crust thickness test, penetration resistance test, and unconfined compressive strength test. The advantages and shortcomings of these methods were comprehensively demonstrated. The results illustrated that the penetration resistance test is the most reliable method in terms of the highest accuracy and relatively simpler operation. It also reveals excellent universality for effectively quantifying the dust erosion resistance of red sand with different particle sizes and for different polymers with various concentrations, while the rest of the methods failed to identify. The application of polymers contributes to improved dust erosion resistance for longer crust failure time, higher solution dynamic viscosity and crust penetration resistance, and higher unconfined compressive strength of rending sand samples. PAM outperformed guar gum and xanthan gum on the base of polymer ionicity and molecular weight. This study offers a better understanding in guiding the selection of optimum evaluation methods and polymers for the study of bauxite residue dust control.

红沙粉尘污染因其职业和环境危害而备受关注。当前的修复技术包括喷水和通过应用聚合物稳定剂进行非传统的稳定化处理。抗粉尘侵蚀性在量化抑制红沙粉尘的有效性方面起着重要作用。本文的目的是评估先前研究中常用的五种静态和动态实验室方法的可靠性和准确性，这五种方法通常用于量化存在聚合物时的抗粉尘侵蚀性能，这些方法是风洞模拟，动态粘度测试，地壳厚度测试，抗穿透性测试和无限制抗压强度测试。全面展示了这些方法的优缺点。结果表明，就最高精度和相对简单的操作而言，抗穿透性测试是最可靠的方法。它也显示了出色的通用性，可以有效地量化具有不同粒径的红沙和具有不同浓度的不同聚合物的抗粉尘侵蚀能力，而其余方法则无法确定。聚合物的应用有助于改善粉尘侵蚀性，延长结壳破坏时间，提高溶液动态粘度和抗结壳渗透性，并提高耐沙样品的无侧限抗压强度。基于聚合物的离子性和分子量，PAM优于瓜尔胶和黄原胶。
