Multifunctional open-pit mine pavement dust suppressant and preparation method thereof

Abstract

The invention provides a multifunctional dust suppressant for pavement in open-pit mines, which comprises the following components in mass percent: 15% to 30% of calcium magnesium lactate, 0.1% to 0.3% of calcium lignosulfonate grafted polyacrylamide, 0.01% to 0.15% of cocamidopropyl betaine, 0.2% to 1% of glycerin, and the balance is deionized water; the preparation method is: (1) graft polyacrylamide with the above deionized water and calcium lignosulfonate Add it into a mixing tank, stir until it is evenly mixed to obtain a mixture A; (2) Add the above-mentioned calcium magnesium salt of lactate, cocamidopropyl betaine and glycerin to the mixture A, stir until completely dissolved, and then let it stand for 60-90 minutes , to obtain a multi-functional surface mine road dust suppressant. The dust suppressant provided by the invention can not only greatly reduce the dust on the mine transportation road surface, improve the environment of the mining area, the dust reduction efficiency is higher than 92%, and the effective dust suppression time exceeds 6 days, but also can greatly save water resources and labor, and has no effect on the environment. harmful, no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control, and in particular relates to a multifunctional surface dust suppressant for open-pit mines and a preparation method thereof. Background technique [0002] Open-pit mine stope roads are mostly composed of gravel and sandy soil, the road surface strength is low, the number of turns is many, and the tonnage of trucks is large. Due to the rolling of vehicles, a layer of fine particle dust is accumulated on the road surface, and mining machinery and equipment will raise a large amount of dust when driving on the road surface of the stope. These dusts have brought serious hazards to open-pit mines: [0003] (1) Cause the dust pollution of the whole mine, deteriorate the air quality of the stope, and induce pneumoconiosis; [0004] (2) Reduced visibility induces various accidents; [0005] (3) Affect the transportation capacity of the car and the efficiency of various mechanic...

AI Technical Summary

Problems solved by technology

[0009] In view of the above-mentioned deficiencies in the prior art, one of the purposes of the present invention is to provide a multi-functional dust suppressant for road surface of open-pit mines. , high energy consumption, the effect cannot meet the requirements of green mine construction and the problem of high dust suppression cost; the second purpose of the present invention is to provide a preparation method of multifunctional surface mine road dust suppressant
