components and designs will be branded as M-
Series fans under the TLT-Turbo Africa offering.
“Marketing ourselves as a single entity under
the TLT-Turbo Africa brand positions us to
expand our footprint and leadership in the
industry both in Africa and worldwide because
we have unique innovations and product
advancements that can now be applied to the
full range of products offered by both TLT
MechCaL and TLT ACTOM,” says Erasmus.
The group has recently supplied a turnkey
TLT-Turbo Africa fan being assembled at factory
in Germiston, South Africa
ventilation solution to Newmont Mining’s
Subika mine, part of the Ahafo complex in
Ghana. The solution will comprise both large
surface fans and bulkhead cooler fans to the
mine in order to ensure efficient ventilation of
the main shaft.
Two axial main surface fans each spanning
2.5 m in diameter and 3.5 m in height, along
with two bulkhead cooler fans were supplied.
The fan design is based on parent-company, TLT
Turbo’s technology while the manufacturing was
managed from TLT-Turbo Africa’s headquarters
in Johannesburg, South Africa.
The project was brought in by TLT-Turbo’s
local EPCM partner, DRA. “As part of the
tendering process for the contract to supply the
fans to Subika, we were required to present not
just products and costing but rather, a solution.
Providing total ventilation solutions for mining
operations across Africa is what we as TLT
ACTOM pride ourselves on and we leveraged our
market knowledge to come up with a simple and
cost effective solution for Subika. This is what
made the difference when a ventilation supplier
was selected for this project,” explains Erasmus.
Newmont received its environmental permit
to build and operate the Subika underground
mine in March 2017. In April 2017, Newmont
announced plans to extend profitable
production at its Ahafo operations by building a
new underground mine and expanding plant
capacity by more than 50%. According to a
statement made by Newmont at the time, the
Subika underground mine is expected to
produce 1.8 Moz of gold over an 11-year mine
life, and features ore grades of 4.7 g/t. The
expansion is expected to improve margins and
support profitable production at Ahafo at least
until 2029.
