Problems solved by technology

However, the cost is high, and the requirements for spraying equipment are high. When used on some minerals with poor affinity with chemical dust suppressants, it cannot play the role of wet adhesion, does not have the function of dust suppression, and cannot be used in metals, non-metals, and coal mines. , non-ferrous metals and other materials are all applicable

Embodiment 1

[0031] The volume percentage of described ultra-high water-curing agent is: water: first curing agent=94:6, water: second curing agent=94:6, two kinds of slurry are made, and the described spraying on the stockpile surface The material layer thickness is 2mm.

Embodiment 2

[0033] The volume percentage of described ultra-high water-curing agent is: water: first curing agent=95:5, water: second curing agent=95:5, two kinds of slurry are made, and the described spraying on the stockpile surface The material layer thickness is 1.5mm.

Embodiment 3

[0035] The volume percent of described ultra-high water-curing agent is: water: first curing agent=96: 4, water: second curing agent=96: 4, two kinds of slurry are made, and the described spraying on the stockpile surface The material layer thickness is 1mm.

[0036] The beneficial effects of the invention are: it can not only suppress dust but also prevent mine damage, low cost, wide application, no pollution, easy to use, can be widely popularized and used, and has remarkable social and economic benefits.

Abstract

The invention relates to a physical dust suppression method for a mine stockpile, which is characterized in that the high-water quick-setting curing agent is partially modified according to the ultra-high water-curing agent volume percentage, and prepared into a slurry suitable for spraying , use Fengshui mixed duckbill sprayer to atomize and spray this solution on the surface of the stockpile to form a thin hard shell on the surface of the stockpile. The high-water quick-setting curing agent is composed of A curing agent and B curing agent. The volume percentage of high water-curing agent is: water: first curing agent = 94 ~ 96: 6 ~ 4, water: second curing agent = 94 ~ 96: 6 ~ 4, two kinds of slurries are made, and the two kinds of slurries are divided by volume The ratio of 1:1 is mixed into a spray slurry, and the spray slurry is quickly sprayed on the surface of the pile after being atomized by a feng shui mixing duckbill sprayer. The material of the invention is non-toxic, harmless and non-corrosive, has fast setting and solidification speed, can not only suppress dust but also prevent mine damage, has low cost and can be widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of a dust suppression method for stacking dust in open air, in particular to a physical dust suppression method for a mine stockpile. Background technique [0002] Mine stockpile dust pollution is a serious hazard, and open-air stockpile dust pollution is one of the important pollution sources. The powder flutters with the wind in the dry and windy season, which not only pollutes the environment but also causes large mine damage. The problem of dust prevention becomes more and more important. At present, the dust suppression method widely adopts the method of sprinkling water at regular intervals. The advantage of this method is that it is simple and easy to implement. The disadvantages are that the maintenance time of dust suppression is short, the frequency of spraying is high, the water consumption is large, and the cost of dust suppression is high. When the water in the powder evaporates, the dust conten...
