Coal dust suppression based on water mediums: A review

2021-10-15  Dust suppression methods based on water mediums are generally divided into three categories as shown in Fig. 1 based on the functions of different methods. The first one is the solution spray which widely applied for suppressing floating dust

A research on dust suppression mechanism and

In order to solve the serious dust pollution problem in mining and loading process of burnt rock open-pit coal mines, a dust suppression technology was proposed to investigate the compound dust suppressant with four functions of wetting, coagulation, moisture absorption, and moisture retention, and improve the hydrophilicity and dust suppression efficiency of burnt rock.

Novel technology for synergetic dust suppression using

2017-7-1  Coal dust is an increasingly serious problem in underground coal mines. This research developed and tested a novel dust prevention technology of surfactant-magnetized water that utilizes the synergy between magnetization and surfactants to markedly improve the wettability of water, resulting in better dust suppression than water sprays alone.

Preparation of microbial dust suppressant and its

2021-10-13  To promote the application of microbially induced carbonate precipitation (MICP) technology for coal dust suppression, two urease-producing bacteria (SZS1-3 and SZS1-5) in a coal mine soil were screened. 16 s rDNA sequencing of these bacteria indicated sequences similar to those of Acinetobacter guillouiae CIP 63.46 and Staphylococcus caprae ATCC 35538, respectively.

Is Water the Best Coal Dust Suppressant? MinTech

Water-only coal dust suppression systems use high volumes of water to wet coal fines and temporarily adhere them to larger coal pieces in order to prevent the fines from becoming airborne. This massive addition of water robs coal of its BTUs (heating value), causes plugging in chutes and hoppers, and creates a slippery environment.

Dust transport law and dust suppression technology based

2021-8-13  In open-pit coal mines where burned rock occurs, because the burned rock is fragile and contains a large number of fine particles, a large amount of dust will be produced in the process of mining and loading. The dust concentration is as high as 2500mg/m3 on average, which seriously affects the health of the workers in the open-pit mine and the atmospheric environment in the mining area. In

What is Coal Dust Suppression? Global Road Technology

2016-2-9  What is Coal Dust Suppression Exposure to dust is a serious health threat to workers in many industries. In coal mining, exposure to coal mine dust can lead to coal workers’ pneumoconiosis (CWP). CWP, commonly called black lung disease, is a lung disease that can be disabling and even fatal.

Method for suppressing coal dust Kittle, Paul A.

In suppressing coal dust by the application of a foam to a falling mass of coal, a continued dust suppression effect is achieved by foaming a water-diluted emulsion of water, a surfactant, and an oil which exhibits a tacky characteristic when in the form of a film in the absence of water at temperatures within the range from approximately 21° C. down to approximately -12° C.
