COST, ENERGY
and ENVIRONMENTAL CONCERNS emphasize need to eliminate quarry haul
trucks, haul roads and ramps
Shovels and trucks (or wheel loaders) have found
a place in quarries as an interfacing connection between face and
primary crushing plant. Trucks require haul roads and ramps in order
to reach feed hoppers of primary crushing plants. As mining progresses
haul distances become longer requiring more or larger capacity trucks
compounding energy costs, competitive, environmental, safety and
community relations problems.
By itself, mobilizing the crushing plant does not
necessarily improve economic results. Ramps must be eliminated to
enable the shortest possible haul distance between face and crushing
plant to fully obtain economic advantage. Conveyors connecting to
the overland conveyor system must be easily moved for blasting.
Provision for removing fines or natural product may be desired requiring
a bridge conveyor or separate surge piles.
Creative Engineering has prepared a 58 page
Quarry Managers Note Book full of ideas detailing practical considerations
on how to eliminate haul trucks, haul roads and ramps. Numerous
photographs and drawings illustrate how others have done it. Examples
using the computer program HAULPLAN demonstrate how to determine
economic advantage using the included Haulplan Data Input Form.
Typical costs are provided supporting use of included Guide To Quarry
Haulage Feasibility Analysis. The Quarry Manager's Note Book and
computer program available free.
