Description

Background
At present, related patents of dust suppression of tailing ponds mainly focus on dust suppression devices and dust suppression materials, mainly comprise wet dust suppression devices, and the dust suppression materials mainly comprise high-molecular dust suppression materials.
The prior art comprises the following steps:
(1) a dust suppression liquid for tailing pond and a dust suppression construction method (publication number: 109621592A). The invention relates to the technical field of mine tailing pond management, in particular to a tailing pond dust suppression liquid. The tailing liquid, sand grains and biomass fiber materials are mixed according to the weight ratio of 100: (3-10): (1-10).
(2) The invention discloses a polymer material (publication number: 103772534B) for fixing sand, soil and dust, which is prepared by the following steps: 30 to 50 parts by weight of polyvinyl alcohol are added per 1000 parts by weight of water.
(3) A rainproof and anti-cracking dust suppressant (publication No. 109321207A). At present, most dust suppressants are sprayed with the dust suppressant to wet or bond dust on the surface of a dust source to realize dust suppression, and the comprehensive performance is poor. The dust suppressant comprises the following raw materials in parts by weight: 2-10 parts of completely alcoholysis high polymerization degree polyvinyl alcohol, 0.01-1 part of gel, 10-30 parts of inorganic filler, 1-6 parts of plant fiber, 0.1-1 part of foaming agent, 1-5 parts of pigment and 40-80 parts of water.
The main components of the existing high molecular dust suppressant can be known to comprise three main types: the film forming agent is a high molecular material, generally an organic cross-linked polymer, the polar groups of the film forming agent can adsorb various substances to form hydrogen bonds, the adsorbed particles form bridging, and one high polymer can adsorb a plurality of particles. The degree of crosslinking between the polymer molecules will form a network. After the storage yard dust suppressant is added into water, the specific surface area of water mist can be increased, the probability of capturing fine particles in dust is improved, the dust is quickly adhered to large particles, and a semi-permanent, rainproof and waterproof polymer protective shell similar to a protective film is formed on the surface of storage yard muck, so that wind erosion is reduced, and atmospheric oxidation is prevented. Thus, the main classes of film formers are: high water absorption resin polyacrylamide PAM, high polymerization degree polyvinyl alcohol, etc.
And (3) filling: the filler is generally composed of starch substances and plays roles of increasing the viscosity of a film forming agent solution and filling consolidation in the dust suppressant.
And (2) a surfactant: because the two materials of the film forming agent and the filler contained in the dust suppressant solution have a certain degree of viscosity, the formed solution is very viscous, meanwhile, because the granularity of a tailing sample is small, the phenomenon that the tailing is rolled up by the dust suppressant dripping liquid easily occurs when the dust suppressant solution is sprayed on the surface of the dust suppressant solution, the film forming crust on the surface of the tailing is influenced, and the penetration of the surface of the tailing can be enhanced by adding the surfactant, so that the surface tension of the dust suppressant solution is reduced.
The fiber medium materials widely used at present are optimally integrated, so that the curing time, the strength of a formed polymer and the dosage of the polymer in the combining process of different polymers and tailings can be known, and the phenomenon of test block rupture in the practical application is influenced by adopting the liquid dust suppressant. Therefore, the scheme increases the wood fiber as the filler and enhances the cracking resistance of the dust suppressant block.
