From a report by Brookings:
"In the next decade, the coal mining industry will likely lose even more jobs to automation. According to a report from the International Institute for Sustainable Development (IISD) in Winnipeg, Canada, the mining industry is primed for automation. It is highly capital intensive, pays relatively well, and buys expensive equipment. The industry has already adopted various automated technologies, including autonomous haul trucks and loaders; autonomous long-distance haul trains; semi-autonomous crushers, rock breakers, and shovel swings; automated drilling and tunnel-boring systems; automated long-wall plough and shearers; autonomous equipment monitoring; and GIS and GPS technologies. All of these technologies are already in use, and their deployment will be ramped up in the next 10–15 years."
