To mitigate the dust dispersion pollution in the open‐pit coal mines, this study experimentally develops a novel environmentally friendly coal dust suppressant. The experiment uses naturally biodegradable soybean protein isolate (SPI) as the main material and utilizes anion surfactant sodium dodecyl sulfate (SDS) to modify SPI. In the carboxymethylcellulose sodium and sodium silicate and ...
Coal mining presents a number of explicit hazards, going from breakdown and flooding to hazardous blasts. Dust made by coal handling plants and mining exercises presents a peril on the grounds that its inescapable nature makes a number of breathing related issues for individuals, just as support and maintenance issues for machinery.
many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers' pneumoconiosis (CWP). CWP is a lung disease that can be disabling and fatal in its most severe form. In addition, miners can be exposed to high levels of respirable silica dust, which can cause silicosis, another disabling and/or fatal lung ...
Coal dust is both a wellbeing and security issue. The high centralization of coal dust created in either open-pit, plants handling coal or underground coal mineshafts can lead not exclusively to the death of excavators experiencing pneumoconiosis yet in addition to coal dust blasts and even gas blasts, which can bring about significant individual injury and financial misfortune.
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.
The research on the law of dust accumulation, migration and diffusion is a necessary link in the development of green mining in open-pit coal mines, and has a certain guiding significance for dust ...

Mining Publication: Characteristics of Fugitive Dust Generated from Unpaved Mine Haulage Roads. Fugitive dust is generated along unpaved mine roads from intermittent equipment traffic. Typically, the majority of such traffic consists of trucks hauling either mine product or waste from the surface mine pit and/or the processing plant.
open pit mining operations along with several alternatives to assess the validity of its results. As a result, three metrics are proposed to evaluate the performance of the emissions control programs implemented in open pit mines. The methodology was applied to 7 of the 8 open pit coal mining companies operating in Colombia. A description of
The excavation can run deep, but unlike underground mining, the activities take place in the open air. That eliminates or reduces some of the risks involved in mining. But working in the open air doesn't mean that workers can breathe easily. Open pit mining produces large quantities of dust, which is a significant hazard in and of itself.
Cypher was recently provided with an abstract of a study conducted on an ROAD//STABILIZR® ® haul road application at an open-pit coal mine in Xilinhot, China, by Shenhua Beidian Shengli Energy Co. Ltd. Following the success of a demo road in 2013, the mining operation built an additional 10km of ROAD//STABILIZR® haul road in 2014.

3 DUST CONTROL The dust control created by the air com-pressor during drilling is necessarily an evil. There are two systems for the acceptance and suppression of dust: 1. Dry dust collection system 2. Dust water suppression (wet method) For dust control, the area surrounding the hole is closed by so called hood dust.

Mining companies need to develop a dust control plan, and supervisors should ensure that dust control systems are working properly for every production shift. Mine workers should be trained on the hazards of over-exposure to coal mine dust. Respiratory protection should be used when dust control protection is being installed, maintained or ...
Our team has over 25 years of experience working with different types of open pit and underground mines, such as copper mines, coal mines, and iron mines. Contact our offices in Canada, Chile, and Peru for more information on how we can help your site and keep you safe from dust and the hazards caused by it.
According to the EPA (AP-42) and National Pollutant Inventory data, dust particles emission from various sources in an open pit mine can be reduced by more than 50% by using water spraying for dust suppression or maceration of excavated ore. Having in mind estimated dust concentrations in the zones of mining operations at open pits, waste dumps ...
The impact of dust from a nearby mine on local amenity depends on the distance from the mine site and climatic conditions such as wind. Concerns about amenity from mine site dust often relate to "visibility" of dust plumes and dust sources. Visible dust is usually due to short-term episodes of high emissions, such as from blasting.
These control measures will prevent coarser dust (10 microns and larger) from becoming airborne and will reduce overall dust throughout an open-pit mine. However, low pressure watering does not actively subdue dust particles that are already airborne or respirable sized dust particles which are less than 10 microns (PM10 dust).
2 Mine dust impacts Mines can be classified as either underground mines or open pit mines. In some cases a combination of open pit and underground mining occurs, although usually sequentially in the mine life-cycle, rather than simultaneously. At underground mines the rock dumps, tailings dams, and load-out facilities are the
The increased air dustiness caused by the aerotechnogenic action of the roads is the key problem of occupational and industrial safety at the open pit mining operations on the open-pit coal mines. The current technologies of the dust control at such facilities are limited mainly by irrigation of the roadway with water from the irrigation machines, that has a number of disadvantages.
S. K. CHAULYA (2005) analyzed the ambient air quality of an open pit coal mining area of Orissa for a period of one year. Drilling, blasting, loading, unloading, transport roads, haul roads, coal handling plants, over burden dumps are the major air pollution sources in mine.
