EXPOSED
Digging, loading haul trucks, and moving overburden happen in mud, dust, and uneven pit walls — physical work language models can't touch, and the machines involved are enormous and expensive. But mining is the single most advanced frontier for industrial autonomy: Rio Tinto, BHP and Komatsu already run driverless haul fleets and remote-operated loaders, and teleoperation centers let one person supervise several machines from a city office, which shrinks seat count fast even where full autonomy lags. MSHA training requirements are safety credentials, not a licensure moat, and no customer pays for a relationship with the operator.
Tasks largely resist digitisation. Reading a face for slabbing, feeling the bucket load through the sticks, spotting a truck in dust, and digging to grade around unmarked utilities or unstable highwalls are still seat tasks at most non-tier-1 operations, which is why this sits at 14 rather than in the mixed band — but it is nowhere near 18, because autonomous drills and remote-operated dozers/loaders have already left the pilot stage at Pilbara and Chilean copper sites.
Hands-on in uncontrolled environments. You are in the cab of a 400-ton shovel or a walking dragline on a bench that changes shape every shift — mud, freeze-thaw slumps, blast dust, night lighting, greasing and track inspections done by hand outdoors — which is uncontrolled-environment work; it is 17 and not 20 only because the operator is seated in an enclosed cab rather than free-climbing the pit.
Certification preferred, not legally required. MSHA Part 46/48 new-miner and annual refresher training plus a task-specific hazard sign-off is a documented competency, not a state licence — nobody revokes an individual credential for a bad dig, the operator isn't personally liable for the citation, and the mine operator carries the Part 100 penalty, which puts this at 5 rather than 0 only because the training records are legally mandatory.
Anonymous artifact production. Nobody buying the coal, aggregate, or ore knows your name; your output is tons on a scale ticket and the only relationship that matters is with the pit foreman and the haul drivers you spot, which is coordination, not a client bond.
Meaningful discretion. You call whether a highwall looks like it's going to slough, when to stop loading and radio the shift boss, how to sequence a cut so the pattern drains and the trucks stay loaded — real discretion inside a written mine plan, ground control plan, and blast schedule that someone else authored, which caps it at 9.
