Trucking in Ramps
While ore production in a mine continues, ore reserves are gradually mined
out, from one level to the one below. When mining passes the lowermost haul-
age level, trains can no longer be loaded through chutes, and dump into crusher.
Developing a new haulage level another 400 m down and extend the shaft,
move the skip station down is a time-consuming and costly adventure. To access
lower levels, miners use the trackless machines. Ore production can continue
downwards with the ramp as access to lower levels. Here the ramp substitutes
for the shaft. The ore carried uphill on the mine trucks, through the ramp, finally
dumping into the old haulage level storage pocket, passing the crusher on its
way to skip filling.
The loaded trucks travel the ramp at low speed, in first gear, full engine
power. Carrying ore on trucks is costly mode of vertical transport, furthermore,
diesel engine are heavy polluters of the underground air. However, there is no
