These practical ideas have been utilized in There is a downside, however, to the use of diesel equipment, especially in the underground mining environment.Sep 01, 2020 The NIOSH Mining Program is working to reduce respiratory diseases in miners associated with diesel emissions by reducing miners exposure to these emissions in underground mines.Jul 28, 2021 Underground mining has its advantages, but there are also disadvantages. Even with all the safety precautions, accidents can happen in underground mining. The risk of an accident is high in underground mining, such as a mine falling apart, an earthquake, or extreme flooding.Broadmeadow has made reducing the potential exposure of our workforce to coal mine dust one of its highest priorities. Our approach is to use technology to remove workers from the coal face, eliminating their exposure to underground coal dust and also eliminating the risk of injury from flying debris during the mining process.

Most of the of exposure to noise in mining comes from the need to use heavy machinery underground, but careful design and new technology and materials can be used to minimize this. Noise assessment in mining plants need to identify noise sources in order to effectively apply the hierarchy of controls.mining - mining - Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered.the complexity in the development of underground mining technologies and designing charging machines for using explosives of these type Mironova amp Borysovska, 2014. Extraction of ores is connected with drilling-and-blasting operations which define efficiency of deposit mining in many respects.

Several of these agents are known or suspect carcinogens arsenic, diesel exhaust, and silica, and some may cause airways inflammation blasting fumes and diesel exhaust.The use of explosives is quite common in mining for various kinds of work. Their handling, storage and application must be carefully considered, as must the risk of explosion of gases and coal dust in underground mines or the potential of flooding.
