Abstract

Open - pit mining generates substantial dust, causing environmental pollution and health threats. This study focuses on a novel dust suppressant, CMC - AA - AM - R. Synthesized with sisal extract fibers as the base, acrylic acid and acrylamide as monomers, and rhamnolipid as a wetting agent, it offers a potential solution to the dust problem in open - pit mining. The reaction's feasibility was verified via HOMO - LUMO molecular orbitals and Fukui functions. Through FTIR, TG - DSC, and SEM, the structure stability was analyzed, and performance was evaluated. Results show good performance metrics like a 34.7° contact angle, strong coal dust consolidation layer shell strength, and good wind resistance. Molecular analysis also reveals enhanced wettability and intermolecular interactions, highlighting the dust suppressant's potential practical value in open - pit mining dust control.

以剑麻叶为原料的生物基抑尘材料在露天矿中的应用优化：分子动力学分析与实验研究

露天采矿产生大量粉尘，造成环境污染和健康威胁。研究了以麻麻提取物纤维为基料，丙烯酸和丙烯酰胺为单体，鼠李糖脂为润湿剂合成的新型抑尘剂CMC - AA - AM - r，为解决露天矿粉尘问题提供了一种可能的方法。通过HOMO - LUMO分子轨道和福井函数验证了反应的可行性。通过FTIR、TG - DSC和SEM分析了结构的稳定性，并对其性能进行了评价。结果表明：接触角为34.7°，粉尘固结层外壳强度高，抗风性能好。分子分析还揭示了增强的润湿性和分子间相互作用，突出了抑尘剂在露天矿粉尘控制中的潜在实用价值。

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
