Description
Technical field
The invention belongs to dust on the roads pollutant abatement technology fields, are related to a kind of dust on the roads prevention and treatment material, and in particular to
A kind of soil-rock mixture structure road dust solidification dust suppressant and preparation method thereof.
Background technique
Coal plays huge effect as one of China's main energy sources, to Chinese national economy, and as society passes through
The development of Ji, demand will be huger.However a large amount of powder is inevitably generated in the exploitation of coal mine, transportational process
Dirt, particularly with the exploitation of open coal mine, due to its open operation and earth's surface is exposed constantly by weathering Erosion, dust
Contamination phenomenon is serious, and wherein carriage way dust pollution phenomenon is severe and processing is difficult.
Carriage way is mainly soil-rock mixture structure, and road surface is made of crushed stone body and subtle powder, medium stone body
Road surface skeleton structure is constituted, fine dust particles then pile up between these crushed stone body gaps by heap.Pass through in vehicle or strong wind passes through
Out-of-date, the fine solid particle in rubble body gap is easily raised with vehicle with the wind, is generated serious fugitive dust harm, is caused live visibility
It reduces, influences the normally travel of coaler, cause serious security risk, while also seriously threatening field personnel's
Physically and mentally healthy and acceleration equipment abrasion.
Currently used dust suppression measure mainly has the treatment measures such as watering dust suppression, dust suppressant dust suppression and surface cure.But
Since the effect of the combined factors such as carriage way soil-rock mixture structure and mining area special climate causes these dust-suppression methods herein
Application effect is bad on kind road.
Watering dust suppression, since the general earth's surface in Open pit Area is relatively exposed, temperature is higher (highest temperature is up to 50 degree or more),
Wind speed is very fast, and under high temperature and wind effect, moisture evaporation is very fast, and subsequent dust is still with the wind with Che Yangqi.Due to row
Lane road surfaces water evaporation rate is too fast, for sufficiently parent profit road surface need sprinkling truck back and forth constantly to sprinkle water, spend cost compared with
Height, and continuously sprinkle water and easily corrode the destruction that roadbed causes carriage way, increase roadbed maintenance cost.
Dust suppressant dust suppression is a kind of by the way that water conservation, hydrophilic component are added into water, is moistened to increase water body to the parent of powder
Degree, reduces the treatment measures of the evaporation rate of moisture in soil or wet powder, and the essence of dust suppression is identical as watering dust suppression.
The watering frequency of carriage way can be extended to a certain extent by the incorporation of dust suppressant, and reduces watering amount, but its
Total workload and watering amount is still very huge, simultaneously because dust suppressant cost itself is just higher, therefore cannot still bring
Preferable economic benefit not can effectively solve carriage way fugitive dust problem still.
Smear thick slurry (cement slurry, pitch, resin etc.) although surface peening or solidification measure can be by link table
The solidification of flour body, temporarily plays good anti-dust effect, but be difficult to penetrate into road table since these hardening slurries are more sticky, only
Form one layer of solidification hard shell on road surface layer, internal powder is not solidified sufficiently.And this layer solidifies hard shell in vehicle loading
Under easily remove, be crushed, uncured powder still can be with the wind with Che Yangqi inside road surface.Therefore these surface cure measures according to
Carriage way fugitive dust problem is not can effectively solve so.
Summary of the invention
Road of the present invention solidifies the liquid slurry that dust suppressant is a kind of low viscosity, has preferable hydrophily and permeability
Can, the powder granule between rubble body can be preferably infiltrated after spilling lower road surface and penetrates into road table certain depth.It simultaneously can be with powder
Body, which reacts, solidifies powder sufficiently, since product of the present invention consolidates carriage way surface layer certain depth soil-rock mixture
Change, improve carriage way bearing capacity to a certain extent, improves road surface and resist the effect of vehicle-mounted and weathering Erosion, dust suppression period
It is longer to come with preferable economic benefit.
Of the existing technology in order to overcome the problems, such as, present invention is primarily aimed at provide a kind of soil-rock mixture structure road
Road dust solidifies dust suppressant and preparation method thereof, to bring good economic benefit and ecological benefits.
