Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much. The deeper the mine, however, the greater the risk. Safety Challenges in Underground Mines
Since the Sago, Aracoma and Darby accidents and subsequent enactment of the Mine Improvement and New Emergency Response Act of 2006 MINER Act , MSHA has investigated new communi ions and tracking technologies.Initially, MSHA conducted a search of available technologies, published a request for information and hosted a public meeting in Washington DC in March 2006.
Using electrical equipment on the job is always hazardous. According to a report prepared by the Fire Protection Research Foundation, there were 1,962 electrical-related workplace deaths during the ten-year period ending in 2013.Almost 200 of those occurred in mines. Compared with other industries, mining is among the most dangerous when it comes to working with electrical power.
