“…The performance evaluation experiments of dust suppression efficacy are divided into physicochemical property experiments and application effectiveness experiments [48]. The experiment on physical and chemical properties allows for the observation of the structural characteristics of the main components of the dust suppressant.…”

Both natural and human-generated dust can cause serious harm to the environment and human health. Since the dust suppressants can accelerate the dust settlement more effectively to prevent the dust from raising; at the same time, to comply with the concept of environmental protection, the use of natural bioorganic materials to prepare dust suppressants has become a research hotspot. This paper summarizes the working principle of dust suppressants and the evaluation indexes of the performance of the dust suppressants, reviews the methods and research results of using bio-organic materials such as polysaccharides, lignin, proteins, microorganisms, agricultural and forestry wastes to prepare dust suppressants in recent years, and puts forward the suggestions on the problems of the current bio-organic dust suppressants to provide a reference for their further development in the future.

“…Coal mine pollution seriously threatens mine production safety and the occupational health of miners, and chemical dust suppression can effectively reduce the concentration of coal dust. The currently recognized dust suppressants can be divided into three types: wetting chemical dust suppressants, condensing chemical dust suppressants, and bonded chemical dust suppressants [29], this is shown in Figure 3.…”

Dust pollution in open-pit coal mines severely restricts the green development of mines. Therefore, dust control has become an important requirement for the sustainable development of the mining industry. With the goal of dust pollution prevention and control in open-pit coal mines, this paper puts forward the concept of a non-disturbance area of an open-pit coal mine. It clarifies the characteristics of dust generation, the coverage area, and the dust particle size distribution characteristics of the non-disturbance area. Taking the dust control at the dump site as an example, the study comprehensively utilizes indoor tests and field tests to develop a dust suppressant for the dump site and determine its dust suppression efficiency and effective service cycle. The results show that the D10, D50, and D90 particle sizes of dust in the non-disturbance area are smaller than those in the disturbance area, and the difference in particle size of D90 is the most obvious. Gelatinized starch and non-ionic polyacrylamide, as the main components of the dust suppressant, can effectively reduce dust pollution in the dump; the optimal concentration is 1.0%, and the dust suppression service cycle is more than one month. The developed dust suppressant does not contain corrosive, toxic, or heavy metal elements. Although the application of a dust suppressant will cause plant growth to lag, it does not affect plant health. The research findings serve as a reference for the zoning treatment of dust in open-pit mines.

“…Although chemical DSPs are increasingly used in dust suppression applications, most existing options still have several shortcomings, such as poor solubility, limited application, or cumbersome application steps, as well as frequent application and a short duration of action. , Little attention has been given to researching DSPs for the harsh environment of continued resistance. The application of polymer organic synthetic materials and other components in DSPs under persistent, high-temperature conditions may easily decompose and produce toxic substances.…”

Most dust suppressants used for buildings currently lack sufficient resistance to harsh conditions, such as high temperatures and wind erosion. To solve this problem, it is necessary to develop a new type of dust suppressant. In this study, the guar gum molecule was chemically modified to remove the active hydroxyl group in order to significantly improve the stability and adhesion of guar gum. Eventually, a composite dust suppressant was synthesized by incorporating a surfactant and an absorbent agent into modified guar gum. The functional groups of the reaction products were analyzed via infrared experiments, thus confirming the success of the modification. Wind erosion resistance and scanning electron microscopy experiments confirmed the improved bonding capabilities of the composite dust suppressant with dust particles. In experiments on wind erosion resistance, the dust fixation rate exceeded 50% after the application of the composite dust suppressant. The results of the thermogravimetric tests showed that the maximum mass loss rate of the samples with modified guar gum dust suppressants was 6.0% and 28% lower than those of the samples with unmodified guar gum dust suppressants and water, respectively. Furthermore, the tests conducted on pH value and corrosion resistance indicated that the pH value of this dust suppressant was comparable to that of tap water and demonstrated a similar rate of metal corrosion. The practical significance of this study is to improve the dust suppressant used in buildings, to improve the performance of dust suppressant and resistance to harsh environment, and to help to continuously improve the health of personnel and environmental protection during construction. The practical significance of this study is to improve the dust suppressant used in buildings, to improve the performance of dust suppressant and resistance to harsh environments, and to help to continuously improve the health of personnel and environmental protection during construction, which has positive practical significance for the building industry and related fields.
