Underground safety of conveyor belts

UNDERGROUND SAFETY. 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. Examples are shown below. DRUM FRICTION

Fire detection and suppression on underground conveyor

On 20th September 2004, a fire occurred on a conveyor belt installation underground at a platinum mine in the western limb of the Bushveld Complex. Nine people died during the fire despite wearing self-rescuer apparatuses and the relative availability of nearby refuge chambers. The cause of the fire was a poorly fitted bearing on the tension pulley that eventually seized due to the

Ensuring electrical safety in underground mining Bender

Electric motors are generally employed for conveyor belts used in mining, which are driven by soft starters or frequency converters. However, these generate critical harmonic vibrations and DC currents which would not normally be present in the feeding AC system. With regular GFCI or simple insulation monitors (e.g. 3 lamp method or 2 voltmeter process), this cannot be monitored with the
