Mar 10, 2021 In order to analyze the present situation of dust hazards in the process of mining in the open-pit quarry and solve the problem of dust pollution, according to the production process characteristics of the open-pit quarry, the characteristics and dust properties of the open-pit quarry were analyzed and studied, and the rules of dust production in the open-pit quarry were obtained.
Feb 15, 2021 In open-pit coal mining, dust produced during coal extraction is a ubiquitous health concern, but other related processes can also produce dust. So, in open-pit coal mines, multiple activities must be taken into account when analysing the environmental conditions in the different sections to ensure safety for the workers and other individuals ...
A study was carried out to establish exposure levels to free silica in an open-pit coal mine in northern Colombia and to verify the control measures implemented by this mine. The intent was to determine, based on sampling, calculation, and analysis of silica concentrations, the exposure levels to free silica within different Similar Exposure ...
A case study of dust and noise management at the Bor copper mine is presented, including an analysis of the efficiency of planned protection measures from dust and noise within long-term planning of copper ore mining and processing at the Veliki Krivelj and Cerovo open pit mines of Bor copper mine.

Qingxiang 40 analyzed dust distribution in a Chinese open-pit coal mine and found that PM concentration is nearly the same throughout the mine, but its concentration is very high around the equipment working area, i.e., 426 gm3. Quite recently, Li, et al. 36 monitored dust in the Pingshuo mining area, China, to reveal concentration change ...
Apr 16, 2018 In this work, a new type of environmentfriendly solidified dust suppressant was developed to solve the dust pollution problem in open pit coalmines, coal bunkers, and so on. Natural polymer chitosan with excellent properties was chemically modified. Infrared spectroscopy was adopted to characterize the product.
CONTROL Of DUST EMISSION AND IMPACTS fROM SURfACE MINES AND WORKS Harold Annegarn PhD ... Current good engineering practice on mines includes many facets of dust control. However, these aspects are seldom coordinated in an overall ... Emissions from blasting and from wind erosion of flat open fields including slimes tailing dams are less well ...
Jun 15, 2021 In 2019, residents of Kiselyovsk, Russia, a city surrounded by vast, open-pit coal mines, made a video asking Prime Minister Justin Trudeau to allow them
respirable dust exposure limits, dust sampling requirements for inspectors and mine operators, a voluntary x-ray surveillance program to identify CWP in underground coal miners, and a benefits program to provide compensation to affected workers and their families.
Mining Product Best Practices for Dust Control in Coal Mining. In light of the ongoing severity of these lung diseases in coal mining, this handbook was developed to identify available engineering controls that can help the industry reduce worker exposure to respirable coal and silica dust.

Dec 19, 2020 It is stipulated that if ever the average concentration of coal dust in the atmosphere is above the levels stated then controls for minimizing dust must be reviewed. Coal mines utilize measures such as ventilation dilution, water spray suppression and stabilizing to prevent dusts although the main one is water spraying owing to its easy maintenance.
