The Hazards of Mining Work Miners have one of the toughest and most dangerous jobs in the world. This is because the job entails the extraction of precious stones and minerals deep within the earth. In addition, miners use heavy machinery and other specialised equipment and tools that can be risky to operate. Safety is a major concern in the mining industry. Mining companies and mining services firms have instituted precautions to ensure the safety and health of their workers. In some modern mines, automation and remote operation have been implemented for the safety of mine workers. Examples of these technologies include automated loaders and remotely operated rockbreakers. Here are some of the dangers that miners face every day. Cave-ins, and Ground and Rock Falls A cave-in occurs when a geologic formation, mine or structure collapses, usually during mining or tunnelling. This underground mining accident occurs when proper safety measures have not been done on the walls and ceiling of the mineshaft; It is also caused from subsidence and also when the mineshaft structure weakens because of cracks in the floor and walls that could occur if the mineshaft is dug too deeply. Advanced methods for timbering and bracing walls and ceilings within sub-surface mines have lowered the number of deaths from cave-ins. However, ground falls still account for a huge number of mining deaths. Gas Explosions Gas explosion is a common accident in coal mines caused by the buildup of methane gas. When methane gas is ignited, more extensive coal dust explosions can potentially occur. To prevent pockets of gas from forming, the work area must be properly ventilated at all times. In addition, make sure the equipment used in coal mines does not have defects that can create sparks and set off an explosion. Methane gas and dust explosions can also be triggered by frictional heat and sparks produced by mining equipment. Because of this, rock cutting sites are cooled with water. Chemical Leaks Ores are converted from their natural state into valuable commodities using chemicals. A leak can occur if the chemicals are not properly stored and mine workers fail to follow strict safety procedures. Miners using the chemicals must also be provided with good ventilation so they do not run the risk of inhaling toxic fumes and dust, which can cause long-term health problems. Electrocution
Miners face the risk of electrocution from using heavy electrical equipment including drills, industrial machinery and lighting. Broken cables or plugs can easily set off explosions. Damp mining conditions also make miners vulnerable to electrocution. Fires Fires in mining sites can happen due to different factors, including gas leaks, electrical defects, or flammable chemical spills. More information here. http://www.reaygroup.com.au/
