目前现有的抑尘技术研究中,对于金属矿尾矿库扬尘灾害的研究相对较少,针对该问题,本文以湖南省永州市东安新龙矿业尾矿库尾砂为研究对象,研制了一种以高倍吸水树脂材料聚丙烯酰胺为基料,丙三醇、海藻酸钠和水性乳化液三种成分为改性材料的新型高分子抑尘剂,并对其配比和性能进行了实验研究,确定了最优配比。实验证明,该新型复合抑尘剂黏度适中,保水性较好,抗水蚀及抗风蚀性能优异,具有较好的抑尘效果。 At present, there are few researches on dust pollution in tailings mine of metal mine currently. In this paper, the tailings sand of tail mine tailings of Xinlong Mine in Dong’an, Dongan City, Yongzhou City, Hunan Province is studied. A kind of new macromolecule dust suppressant based on polyacrylamide with high water-absorbing resin material, glycerol, sodium alginate and water-based emulsion as modified materials, and its proportion and performance were studied experimentally , Determine the optimal ratio. Experiments show that the new compound dust suppressant has moderate viscosity, good water retention, excellent water and air erosion resistance, and good dust suppression effect.
