1. The use of energy criteria to establish the mine boundaries corresponds to the role of coalmining enterprises as subsystems within the energyproduction system. The criteria here proposed reflect the level of technology not only within coal mining but also within the power industry and in transportation. It is important that the parameters included in the criteria have a physical basis ...
· At the Wahana open pit, more than 8,000 t of coal were recovered from the low wall toe area, prior to the cracking, breakup and destruction of the coal seams in the slide mass. 24/7 monitoring with SSRXT, in combination with Bayan best practice safety procedures, made the coal recovery possible with no injuries or loss of equipment – coal recovery value 1 million
Open Pit Mining. Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.
