YZZ vibration flow aiding machine is a newly developedore drawing device, which is devised on the basis of the theory of autogenuous synchronization and directional vibro excitation.
The oil industry has also developed remotely-operated vehicles to make trenches for seabed pipelines, which can be adapted for cutting ore, even though it may lie much deeper, at, say, 1.5km down.
It has met some resistance from developed nations like Australia in its quest to buy up mining and iron ore assets, but has been largely successful in Africa.
