Flooding may not be the first thing that comes to mind when thinking about mining hazards, but mine floods can cause catastrophic accidents. Mines flood from collapsing, surrounding dams breaking, flash flooding, and excessive ground water intruding Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust MSHA offers a wide variety of mine safety and health materials to assist trainers and mine operators in promoting a safe and healthy environment at U.S. mines. We are always looking for new materials to share with the mining community. Please contact us at mshatraining@dol.gov if you have any materials to share, or if you have any questions or suggestions regarding the safet Fire, flood, collapse, toxic atmospheric contaminants, and dust or gas explosion are the most critical hazards specifically linked to underground mining. Blasting related hazards must also be added to that list Whole body vibration (WBV) is a slow forming physical hazard that occurs in mining workers and other occupations that work with heavy machinery. In the mining environment, WBV can be caused either by spending a lot of time sitting on machinery, which is most of the time in mining extraction, or by standing, such as working on jumbo operators

This workbook is designed to give the user a starting point to identify and manage hazards at the mine site. It is a step-by-step approach to identify hazards, assess risks and implement controls. It is consistent with other NSW Mine Safety Operations publications such as the . Risk Management Pocket Guide . and the . General Workplace. Rockbursts present hazards that are particular to hard rock mines. Factors that affect seismicity at a mine include rock characteristics, pre-mining stresses, the presence of geological structures, the amount of material extracted and mine sequencing. Figure 2.3 shows damage mechanisms caused by rockbursts

The mining industry has made significant improvements in health and safety over the last decade, reducing the incidence rates of both fatalities and serious injuries. However, the mining industry still has one of the highest rates of fatalities of any industry. In the 12 years to 2015, the fatality rate in the mining industry decreased by 65%. Electrical safety basics. Don't work with exposed conductors carrying 50 volts or more. Make sure electrical equipment is properly connected, grounded and in good working order. Extension cords may not be used as permanent wiring and should be removed after temporary use for an activity or event. Surge suppressors with built-in circuit breakers. Hydraulic fluids are widely utilized in many industries, such as mining and construction, for power transmission. Most hydraulic fluids are combustible and are used under high pressure to transmit power or motion. Pressurized oil in hydraulic systems presents a considerable fire hazard, particularly where ignition sources are present A confined space also has limited or restricted means for entry or exit and is not designed for continuous occupancy. Confined spaces include, but are not limited to, tanks, vessels, silos, storage bins, hoppers, vaults, pits, manholes, tunnels, equipment housings, ductwork, pipelines, etc. OSHA uses the term permit-required confined space. The most serious health hazard associated with uranium mining is lung cancer due to inhaling uranium decay products. Uranium mill tailings contain radioactive materials, notably radium-226, and heavy metals (e.g., manganese and molybdenum) which can leach into groundwater. Near tailings piles, water samples have shown levels of some.

HSE - MINING: Safety Alert - Fatal Nip-Points on Conveyor

Of all the hazards associated with mining, rockbursts are perhaps the most terrifying. A rockburst is the sudden, violent dislocation of slabs of rock in a tunnel, usually from the walls, but also potentially from the roof or even floor In addition, the list of historical coal mining disasters is a long one, although work related coal deaths has declined substantially as safety measures have been enacted and underground mining has given up market share to surface mining. Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions. Open cut. Mining is the extraction of minerals and other geological materials of economic value from deposits on the Earth. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes The deadly accidents highlight the perils of mining in China. Despite recent safety gains, China remains home to the world's deadliest coal mines, resulting in more than 1,000 deaths last year Surface mining can also directly impact the health and safety of surrounding communities. Mudslides, landslides, and flashfloods may become more common. And depending on the chemical makeup of the coal deposit, mines can pollute local drinking water sources with toxic chemicals like selenium, arsenic, manganese, lead, iron, and hydrogen sulfide.
