dust control in open pit coal mine

Dust Control in Coal Mining - where coal mining meets ...

Jan 27, 2021  Open-pit coal mine operations generate a substantial amount of dust and other particles into the atmosphere. Towns within the vicinity of coal mine operations tend to bear the brunt of coal dust generated from these mining activities but in the discussion at hand, we evaluate the effect of coal dust on agricultural production.

3 innovative dust control measures for open-pit mines

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).

Dust Suppression in Coal Mines - Global Road Technology

Dec 19, 2020  Coal dust is both a health and safety issue. The high concentration of coal dust produced in either open-pit or underground coal mines can lead not only to the death of miners suffering from pneumoconiosis but also to coal dust explosions and even gas explosions, which can result in major personal injury and economic loss.

IMPACT OF DRILLING IN THE OPEN PIT MINING ON THE

For dust control, the area surrounding the hole is closed by so called hood dust. "Hoods for dust" are closed by the side with curtains. The dust control system on the drill must be used in combination with dust hood and curtain. The two most common types of dust control are dry dust collectors (dry method), and water injection (wet method).

Air quality management: a mining perspective

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

Mine dust and you - Fact sheets

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.

Health Hazards of Mining and Quarrying

Respirable coal mine dust is a hazard in underground and surface coal mines and in coal-processing facilities. It is a mixed dust, consisting mostly of coal, but can also include silica, clay, limestone and other mineral dusts. The composition of coal mine dust varies with the coal seam, the composition of the surrounding strata and mining methods.
