"I Inspect Abandoned Mines. One of Them Has a Ventilation System That’s Still Running" Creepypasta

[ominous music] I work for an environmental risk contractor that assesses long-term stability risks. Most of what we audit are sealed industrial spaces, old tunnels, refineries, quarry cuts, et cetera. Places that were shut down decades ago and are now the local council's problem whenever someone reports a smell in the cellar or a sinkhole opens in a field. Methane buildup is the usual concern. Sometimes groundwater ingress changes the internal pressure enough to compromise whatever plug was used to seal the site. In worst case scenarios, slow collapse can propagate outward through the surrounding soil, destabilizing nearby roads or foundations. That's the sort of thing we're meant to catch early before an old shaft turns into a housing insurance claim. The site that came through last Tuesday didn't look unusual at first. It was a disused mine in rural Wales, sealed in 1948 after a subsidence event killed three surveyors during a post-war inspection. According to the closure report, all ventilation infrastructure had been dismantled prior to sealing. The primary shaft was backfilled with concrete and capped. Secondary access tunnels were collapsed using controlled charges. By 1953, groundwater ingress had flooded the lower
