Hard rock revolution on the horizon Continuous mining

Different ApproachesSmaller, More Flexible MachinesLong JourneyBetween The Rock’s Hardness and The Industry’S Resistance to ChangeThe BenefitsThe biggest problem with mining hard rock is that it is difficult to break mechanically and that poses challenges in advance rates and energy use, not to mention how quickly it wears down cutting parts. Each manufacturer is using a different approach to increase the wear life of components and reduce the time and energy it takes to break the rock. Caterpillar’s HRM220 has numerous picks mounted on two cutting heads to hit the rocSee more on magazine.cim

Longwall mining Wikipedia

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6–1.0 m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (1.9–2.5 mi) long and 250–400 m (820–1,310 ft) wide.get price
