Nov 20, 2020 The focus narrowed slightly to open-pit electrification during Dr Bappa Banerjees talk, An electric future for mine haulage. Dr Banerjee, General Manager of Mining Equipment for Wabtec, emphasised from the off that there was no one-size fits all solution to going electric in this sector.
Mines use a combination of GroundHogs Telematics and the tablets built-in GPS modules to continuously track the time spent in each phase of the LHD cycle. Context sensitive algorithms use the data from the GPS and the Telematics modules to determine the current state of the machine whether it is hauling, dumping, traveling, waiting or is just idleparked.
Open-pit mining is an extremely effective surface mining technique for extracting minerals, coal and other useful materials that are covered by relatively thin overburden layers. However, it takes the right equipment to penetrate the surface rock and reach the underlying layer in a timely and efficient manner.

In-pit belt conveyors are used to move material within a large, active mining pit area or from the pit to loading areas for further distribution within the mine. In-pit conveyors may also move mined material to portable crushing systems that reduce the size of larger rocks or minerals for easier transport.
equipment, which may include a mining loader, shovel or excavator. Loaders lift the ore or waste material onto the trucks for removal from the mine. In an open-pit mine, loader types can include electric rope, hydraulic excavators including backhoe excavators, and front-end loaders also called wheel loaders Ercelebi and K rmanl , 2000.
Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
