underground coal mines to protect conveyor belt installations have been in place since the Coal Mine Health and Safety Act of 1969 was enacted. Over time, the coal conveyer equipment being used and ventilation conditions underground have changed significantly, particularly the width of the conveyor belts and the use of belt air at the face. The effect of these new conditions on

A weaker AMOC means a slowdown in the conveyor belt effect in the North Atlantic that pulls warm water up towards Europe. This finding is consistent with direct measurements of the AMOC by the RAPID project – a collection of instruments tethered to the seafloor across the Atlantic Ocean that monitors temperature, salinity and current speed at different depths.

Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust. The fire safety requirements are similar for the most hard coal mining countries.
