Talbot Group Investments

Location:
Tete Province, Mozambique

GIBB’s Responsibilities:
The Minas De Revuboe mine is located in the Moatize Basin and provides a world class coal mine producing coking coal and thermal coal for the global market, with the potential to process up to 17 Mpta.

GIBB’s scope included the survey, demining, railway line and water management elements of the project. Key features included topographical surveys, general mine action assessment and demining. Water studies included hydrology, flood hydrology, sedimentation, geohydrology, and groundwater and surface water quality studies.

The engineering components included design of water storage dams, bulk water conveyance system, flood water diversion canal design, railway bridges and culverts, relocation design, signalling and telecommunications design, railway balloon and yard lighting design. Train operations and a rolling stock study were also completed.

Ausenco Sandwell

Location:
Nacala, Mozambique

GIBB’s Responsibilities:
Nacala Coal Terminal is a greenfield coal terminal which has been developed in Mozambique, designed for 24 MTPA of both coking and thermal coal from mine operations in the Tete Province.

The terminal is a long term solution with large potential for expansion as Nacala is a natural deep water port capable of handling large bulk carriers. It is a world class coal facility operating at very high levels of efficiency.  GIBB’s specific scope included the stock yard terrace, railway alignment, and drainage design elements of the project.

Client:
Sasol Mining

Location:
Mpumalanga, South Africa

GIBB’s Responsibilities:
By the year 2025, Sasol Mining anticipates the deployment of production sections within the Alexander coal blocks. This forms part of Sasol Mining’s plan to fulfil their 2050 mandate to supply coal to the Secunda Synfuels Operations (SSO).

GIBB Mining’s task was to conduct the feasibility study on the project, which is expected to yield between 6-8 million t/a of coal. GIBB Mining was also responsible for the mine design within the first 1 km radius of the box cut to tie into the overall mine plan.

This encompassed all geotechnical and geohydrological studies, bulk power, water supply, materials handling system design and all supporting infrastructure including offices, buildings, workshops, sewage treatment and a 20 km mine access road.

RSV USA / LUNDIN MINING (SOMINCOR)

Location:
Castro Verde, Portugal

GIBB’s Responsibilities:
GIBB provided optimisation studies to upgrade the shaft at the Santa Barbara Shaft operations at Neves Corvo Mine in Portugal. The changes were to increase hoisting production from 5.4 to 5.6 million t/a.

GIBB Mining provided the project management, including the management of sub-consultants and sub-contractors. Additionally, construction drawings were prepared and continuous onsite assistance was provided for the period leading up to, and including, the shaft shutdown to implement the changes.

The work resulted in improvements in the hoist duty cycle, the implementation of infrastructure to reduce shaft downtime during maintenance, and replacement of inefficient equipment.

Client:
South32

Location:
Mpumalanga, South Africa

GIBB’s Responsibilities:
The Khutala Colliery is contracted to supply the ESKOM Kendal Power Station with coal from the No.4 Upper (U) Seam and the No. 2 Seam reserves until 2033.

The purpose of the Khutala Block A West project is to extend the life of the underground operation by accessing an approximate 38Mt of ROM coal via a decline shaft equipped with a bulk material handling system and one-way traffic flow.

GIBB tracked the progress of the concept level design completed by South32 to a feasibility study level of design that provided the knowledge for accessing the Block A West reserves safely while seamlessly enmeshing with the existing Khutala operations.
