Dams and Water Works
CARES are a leading body in the field of dam engineering, with worldwide experience in providing
consultancy to the mining industry providing:
- Hydraulic modeling
- Designs
- Feasibility studies
- Restoration plans
- Pollution control structures
- Flood protection systems
- Ground water investigations
For:
- Tailing dams
- Discard dumps
- Waste water storage facilities
Geotechnical Services
CARES geotechnical division can offer services in a range of sampling and analytical sectors,
from initial surveys to clean up and long term site monitoring. We are also able to supply on
site testing and supervision.
- Geological sampling
- Vertical mapping and analysis
- Borehole Management
- 3D visualizations
- Porewater sampling
Social and Environmental Responsibility
CARES have over 20 years expertise focusing on the collection, interpretation / analysis and
presentation of the natural, built, social and economic environments, integrated with spatially
related needs. CARES experience also includes the consideration of environmental factors, client
representation and management of environmental specialists and scientist involved in monitoring
and assessment, and also providing commercial advice, preparing business cases, land use
development briefs and strategic documentation including development & and regeneration master
planning.
Mine Waste Management
CARES has extensive experience in the field of tailings dam and waste
engineering, having designed and developed waste management facilities worldwide and provides a
tailored, engineered solution and suitable geotechnical investigations to suit the complexity and
risks associated to the project.
CARES is able to offer services from conception design to tailing dam closure,
including the following elements:
- Geotechnical site investigation
- Physical and chemical characterisation of waste materials
- Stability analysis
- Construction scheduling
- Disposal systems
- Environmental permitting to country legislation
- Closure and rehabilitation planning
We have had significant experience of working with conventional disposal
methods including:
- Slurry disposal to a ring containment wall on relatively flat ground with a
centrally-located decant facility
- Slurry disposal to a valley storage
- Slurry disposal to a series of cells with tailings deposition cycled between the cells to
facilitate consolidation and desiccation
- Down valley discharge of thickened tailings towards a containment wall, located at the
head of a catchment
We are able to integrate pioneering technologies wherever possible, in order to
optimise tailings delivery methods.
CARES can provide both short term and long term monitoring plans for tailings
storage facilities, both for existing facilities and during the design of new facilities.
Monitoring provisions should include:
- The installation of piezometers to monitor groundwater
- Surface and groundwater quality sampling
- Monitoring reports prepared at appropriate
CARES’ team of Engineers and Scientists work together with the client to ensure
that the most cost effective and appropriate techniques are applied to their operation.
Current Activity
At present CARES are actively involved in a number of projects for Avocet Mining
in Burkina Faso. Most recent is the design of a labyrinth spillway that offers a cost effective
design plan, that provides a low maintenance solution and minimises construction materials required.
In addition to this, CARES are currently designing the final deposition plan for the mine’s current
Tailings Management Facility (TMF) which is approaching the end of its operational lifespan. We are
also providing on-site supervision for the implementation of both the design of new spillway and the
TMF.
