Robotic innovations like Rail-Veyor's conveyor system for hauling materials in and out of mines are taking some of the human factor out of mining, making it more efficient and safe for workers. (Source: Rail-Veyor Technologies)
It isn't only the safety issue that drives the need for robotics in the mining industry. I used to work in the industry for a number of years and another disadvantage is that the minerals are in the middle of nowhere. (Actually, you fly into the middle of nowhere and then drive another 100 miles). The personnel costs are astronomical because the miners have to be located at the site and their families are elsewhere. In some instances, even infrastructure (such as water systems) need to be brought out to the mine, so the less people actually there, significant reduce the costs.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
