A mine generates inspection records every shift: workplace examinations, ground control checks, conveyor and guarding inspections, mobile equipment pre-starts. In the US, MSHA requires workplace examinations by a competent person; in the EU, Directive 92/104/EEC sets minimum health and safety requirements for surface and underground mineral extraction. The records exist. The pattern across them, a ground condition noted four times in a month in the same heading, is what gets lost.
Safety is also where a wrong answer is not symmetrical. A system that flags too much costs some review time; a system that misses a hazard and implies an area was checked is dangerous. So the design rules are fixed: the model only raises findings, it never clears an area, never closes a finding and never replaces the examination. A missed hazard in testing is not a metric to improve; it is a stop.
