Exposure to dust in mining and quarrying continues to be a major risk to the health of workers. Breathing in dust, such as coal dust, silica dust and other finely powdered materials, can damage the lungs and airways. The risk to health varies depending on the size and nature of the dust particles.
Dust is classified as fine, dry particulate matter and can be made up of pollen, minerals, soil, and many other particulates found in the local environment. Companies in the mining industry are tasked with monitoring and controlling their dust emissions, because dust is created in every step of the mining process: mine construction,
The effects are felt more in the arid areas of Australia and unfortunately economic activities such as mining predominantly use water for dust control. Ten years ago, in the Pilbara region in one particular month up to 70% of the regions water was utilized in mining activities with up to 50% of the water in Harding Dam expended for iron ore stockpile dust control at the ports.
#0183;#32;Methane and Consecutive Coal Dust Explosions . Methane is a highly explosive gas trapped within coal layers. Mechanical errors from improperly used or malfunctioning mining tools (such as safety lamps or electrical equipment) or the use of improper explosives underground can trigger methane and initiate consecutive coal dust explosions.
#0183;#32;DCT manufactures fog type dust control equipment that uses compressed air and water to produce water droplet sizes of 1100#181; for and larger dust particle capture. This technology meets US EPA clean air requirements. Engineered transfer chutes for dust control. DCT offers different technologies for keeping the mining industry clean and
The appropriate design and installation of dust collection equipment will not only reduce emissions, but allow mining equipment to operate for longer intervals and improve mill productivity. For example, AIREX DCCHSB amp; Baghouse Series dust collectors have been successfully tested at g/dscf emissions on heavy duty rock crushing (ex. primary jaw crushing, secondary hammer mills).
Crystalline silica is found in concrete, masonry, sandstone, rock, paint, and other abrasives. The cutting, breaking, crushing, drilling, grinding, or abrasive blasting of these materials may produce fine silica dust. It can also be in soil, mortar, plaster, and shingles.
Most of the products are derived from either synthetic polymer products; water absorbing salts; petroleum based products; organic based products; electrochemical products; clay based products; or
The mining industry has undergone numerous changes in recent years. With each change brings new opportunities and new obstacles. As companies look into 2017, here are what we consider the top business risks facing the mining industry.
dust containing metals such as lead, cadmium and arsenic asbestos. The geology of the rock and mining activities to extract and process the rock will determine the type and quantity of dust particles generated. Health and safety effects of dust Breathing in dust can result in a range of occupational illnesses and diseases depending on:
The electronics industry is one of the huge industries. This is the type of industry that produces electronics devices for commercial as well as domestic use, for example, smartphones, switches, circuit board, refrigerators, washing machines, and other AIbased goods. Electronic companies produce, market and sell electronic units.

MAJOR MINING INDUSTRIES The four mining industries which are probably the largest sources of. fugitive dust nationally are coal, copper, crushed stone, and phosphate rock mining. These . industries are each described briefly in. this chapter to provide a basis for evaluating the extent and impacts of fugitive dust air pollution from mining operations.
Mining operations create significant amounts of dust and gasses. Many of these dusts consist of very small particulates that are respirable. If exposure to these respirable dusts reaches certain levels, workers health could be seriously threatened. Even a dust as common as silica can lead to serious health problems.
#0183;#32;Types Of Dust. July 31st, 2014 General. In its most basic form, dust consists of small particles that float throughout the atmosphere. Depending on the environment or industry being worked in, dust can mix with anything from pollen, to skin cells, to harmful pollution particles.
Mining Industry submitted by Sri Amol Paithankar (Roll No. 107MN026) in partial fulfilment of the requirements for the award of Bachelor of Technology degree in Mining Engineering at the National Institute of Technology, Rourkela is an authentic work carried
People living near mine sites often ask about the effects of dust emissions in the air as a result of mining activities. This fact sheet has been prepared to explain the type of dust that is generated from mine sites and the potential risks from mine dust to health.
