Description
Technical Field
The invention relates to the field of dust inhibitors, in particular to a pavement dust inhibitor.
Background
The surface of the stope road is mostly composed of broken stones and sand, and a large amount of fine particle dust is gathered on the surface of the stope road due to the use of large stripping, mining, loading and unloading and transportation equipment in the process of surface mining, the interaction force among the dust particles is small, a large amount of dust can be lifted when natural wind or automobiles run, and particularly, a large-scale transport vehicle runs on the stope road surface. The dust on the road surface not only causes the pollution of the whole mineral dust, deteriorates the air quality of the stope and induces pneumoconiosis, but also the high-concentration dust can influence the transportation capacity of the automobile and the efficiency of various mechanical equipment in the stope, accelerate the abrasion of the running parts of large equipment and increase the power consumption. Therefore, the related technical measures are adopted to control the surface dust emission of the surface mine and reduce the influence of the surface dust emission on the air quality of the mine environment, and the problem that the surface dust emission needs to be dealt with in the current mining process is solved.
The traditional road surface dust-proof method is to sprinkle water by a sprinkler, namely a wet dust-proof method, but the moisture on the dry soil road surface in high-temperature summer is evaporated and permeated quickly, so that the dust cannot be effectively prevented. In addition, frequent watering operation is difficult to realize on the site of the open-pit mine transportation road, and the frequent watering operation can cause the lower-grade road surface to be more damaged, thereby increasing the abrasion of automobile tires and shortening the service life of the automobiles. The other road surface dust-proof method is to directly lay high-grade cement or asphalt road surfaces, but because a large amount of crushed stone and soil are inevitably scattered in the process of carrying ore rocks by a truck, the raised dust of the road surfaces still exists, and the high-grade road is not allowed to be laid in open pits economically and technically. Therefore, it is necessary to develop a road surface dust suppressant with high dust suppression efficiency and long effective dust suppression time.
