ULMA Working On Mining and
Hydropower Expansion
ULMA has many years of experience, a wide scope of expertise
in this area and has carried out a considerable number
of projects in Peru.
The growing demand for energy that comes with the
fast development in the country has led to a multiplication
of the construction of energy infrastructure. This has
brought an increasing demand for ULMA solutions, given
the proven expertise in the country.
Expanding Mining Operations
With prior experience from 2007, ULMA gets involved for
the second time in this project, this time, in the expansion
of the Cerro Verde mine managed by GyM S.A.
This expansion is going to triple the ore processing capacity
of the mine that produces more than 20% of the
copper of the country to 360,000 tonnes.
ULMA has provided specific solutions for this project.
The 2.5 m thick slab required extra horizontal reinforcement
against heavy wind that significantly increased the
weight of the structure. The bracing of the T-60 shoring
towers helped increasing their load capacity by more than
1 tonne to support the slab.
Hydroelectric Power Plant, Cerro
del Aguila
One of the largest projects currently in progress and one
that will become the second largest hydroelectric power
plant in Peru is Cerro del Aguila with a production of 510
MW.
The project means a real challenge due to the technical
complexity, but also because of the location and the difficult
access to the area.
A consortium of GyM and Astaldi appointed ULMA as
formwork supplier for the construction of the dam, the
powerhouse and the intake.
The dam is 80 m high
and 270 m wide at the
crest.
The expansion of the
iron ore mine operated
by Cerro Verde
Mining Company,
Arequipa, Peru, will
triple the processing
capability.
