Coal dust sink tests were performed with the wetting agents at solution concentrations of 0.05% (1:2000), 0.1% (1:1000) and 0.2% (1:500) by volume in water. It must be noted that this range of solution concentrations are initially recommended for coal mine dust control with further adjustments made to match a particular mine's dust control needs.
Experimental study of the dust-removal performance of a …
A variety of dust control methods are often applied in coal mines, among which the application of wet scrubbers has proven to be an efficient technology for the removal of dust in airstreams, rather than diluting or confining the dust. In this paper, a wet scrubber design was developed. Based on a self-designed experimental test platform, …
Dry-screening of damp coal Laboratory tests …
The main problem experienced with dry screening is that the coal received from the mining operation is rarely completely dry. Raw coal received from the mining operation can contain varying amounts of moisture and this complicates the screening operation significantly. The main concern when screening damp coal is blinding of the screen ...
Implementing Dust Suppression
Vehicle movement, maintenance, and waste disposal also contribute to dust emissions. To combat this issue, mining companies employ various suppression techniques, such as water spraying, dust collectors, and enclosures. Effective control at the source helps mitigate the environmental and health impact of dust emissions in mining.

Preparing your Dust Control and Suppression Management …
Dust prevention is a method of increasing the material's moisture content to avert dust particles becoming airborne. Dust control refers to increasing the moisture or humidity of the air to capture already airborne dust particles. One must first determine the application, prevention or suppression (i.e. dust control) that needs to be implemented.

As a basic energy source and an industrial raw material, coal has had an important contribution to China's economic development [1].Owing to rapid development of the coal industry and the continuous improvement in mechanization, mining scales and coal usage have dramatically increased [2].However, during coal mining, …
Dust suppression system in coal mining operations
Coal mining operations result in hazardous dust emissions that may affect the health of mining employees and surrounding environments if the appropriate dust suppression systems are not installed. The ROM Tip Misting system is a unique tailor-made solution for dust suppression of fugitive dust, generated at transfer points and crusher plants.
Analysis of coal dust consolidation performance and
Therefore, it is crucial to take the necessary measures to control coal dust. Coal dust suppression methods are mainly water dust suppression [8], chemical dust suppression [9], and biological dust suppressants [10], but due to the hydrophobic nature of coal dust, the high surface tension of water, and the fast evaporation rate, coal dust …
A systematic review of occupational exposure to respirable coal …
Respirable coal mine dust (RCMD) is a mixture of more than 50 elements and their oxides. It is estimated that 40%–95% of respirable dust in the underground coal mine is pure coal, and the rest contains particles originated from cutting roof and floor rock, diesel exhaust from equipment, and rock dusting (Walton et al. 1977; NIOSH …
