Chevron-MegaPipe ®
IPCC in combination with steep-angle
conveying systems – an ideal
opportunity for more efficient
haulage in open-pit mines.
Up to the mid-term life of a hard rock open-pit
mine haul-truck fleets offer the significant
advantages of relatively low initial capital costs,
redundancy and flexibility. But when a pit has
reached a certain depth, the increasing costs
of truck haulage will inevitably lead mine operators
to start searching for alternatives.
A stationary pipe conveyor system linked to a crusher station
at the bottom of the mine is just such an alternative solution –
and in fact offers many advantages. The tail station (tension station) is based
at the bottom and the head station (drive station) is located at the rim of the open
pit. Depending on the inclination, the conveyor bridges are mounted perpendicular
to the benches of the open-pit mine. An inclination of up to 40° is possible and a
service cab driven by a rope winch is provided for maintenance and inspection
along the structure. What’s more, the Chevron-MegaPipe ® steep-angle conveying
system can also be designed for large-scale conveyance applications.
The system’s key components are the world’s largest and heaviest profiled pipe
belt, which was developed by ContiTech with a max. diameter of 900 mm, a width of
3,200 mm and a strength of 7,500 N/mm, and the innovative DirectDrive ® concept
from Siemens. These drives come in a proven design with installations of 6 MW.
The Chevron-MegaPipe ® steep-angle
conveying system brings numerous
benefits:
• System inclination angles of up to 40°
• Conveying capacity of up to 8,000 t/h
• Material: pre-crushed ores, coal or overburden
with a grain size of up to 350 mm
• Mine depth of up to 500 m
• Vertical and horizontal conveying
curves possible
• Fewer heavy-duty trucks required
• System fully operational in inclement
weather conditions (e.g. fog, snow or rain)
• Extensive automation of conveying
system possible
• Significant minimization of noise,
dust and CO 2 emissions
• Reduction of operational, personnel and
investment costs (capex/opex)
