The future development of such technology is an integral part of several plans involving the mining of moons and asteroid belts for ore and other materials, the creation of lunar factories, and even the construction of solar power satellites in space. The von Neumann probe [7] is one theoretical example of such a machine.
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Test bench for a miner's closed circuit self-rescuers. A self-contained self-rescue device, SCSR, self-contained self-rescuer, or air pack is a type of closed-circuit SCBA [1] with a portable oxygen source for providing breathable air when the surrounding atmosphere lacks oxygen or is contaminated with toxic gases, e.g. carbon monoxide.
Automated mining involves the removal of human labor from the mining process. [1] The mining industry is in the transition towards automation . It can still require a large amount of human capital , particularly in the developing world where labor costs are low so there is less incentive to increase efficiency.
