After carbide lamp open flames were implicated in an Illinois coal-seam methane gas explosion that killed 54 miners, the 1932 Moweaqua Coal Mine disaster, [7] carbide lamp use declined in United States coal mines. They continued to be used in the coal pits of other countries, notably the Soviet Union.
In Sun Haven, a minecart is used for players to traverse between floors in the mines while other farm sims use lifts. In Great Britain, restored mine carts (known as "tubs") containing floral displays can commonly be seen on village greens and outside pubs in former coal mining areas such as Northumberland and County Durham.
When they came into regular use, barometers were used to tell if atmospheric pressure was low, which could lead to more firedamp seeping out of the coal seams into the mine galleries. This continued to be essential information even after the introduction of safety lamps; at Trimdon Grange there was an accident involving pressure.
