Energy efficiency assessment of electric shovel operating

Energy efficiency assessment of electric shovel operating

Benchmarking energy consumption is a method for evaluation of the minimum energy consumption in any industry. Energy efficiency benchmarking for mining system has been developed by Wang et al. and Sahoo et al. [7,8]. Electric shovels consume about 32% of the total electrical energy usage in an opencast mine . Energy efficiency indices have been

Water and energy assessment for dewatering in opencast

Dec 01, 2014 Energy cost is important for controlling the cost of production in any industrial process. For mining, it accounts for about 15% of the total cost of production (Colorado efficiency guide, 2013). Energy cost for dewatering is significant in opencast mines and can be minimised by reducing the specific energy consumption (SEC)

(DOC) Extreme Energy: From opencast coal-mining to shale

Open-cast coal mining, and the current political favourite, shale-gas fracking, are supposed to provide energy security and shore up our ailing economy. As we have seen, however, fluctuations in the global market for fuels can undermine these dirty and myopic energy strategies almost in the blink of an eye

Reading: Open-Pit Mining | Geology

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is
