KLM Consulting Services (KLMCS) is a multi-disciplinary consulting company, specializing in mine dewatering, slope depressurization and management of water resources. KLMCS was established in 1989 and is a recognized leader in the field of water supply, mine water management and mine-dewatering in Southern Africa. It is an expanding, highly specialized company, continually striving to offer clients innovative technology to achieve cost effective, appropriate designs for municipal, mine and industry.

Dr Kym Morton is the founder and Managing Director and has over 37 years’ experience in consulting on ground water projects. The large number of successful projects completed by the company is testimony to her and the staff’s technical ability. In 2006, KLMCS Botswana was established by KLMCS South Africa, in partnership with Botswana citizens to provide expert groundwater consulting services to the Botswana mining industry. In 2010 a Scottish office was opened.

MISSION

KLMCS is committed to providing the most applicable technology for solving ground water problems. Our Clients are assured of complete dedication to accurate collection of relevant data, presentation of information and of performing cost-effective analysis, so as to increase knowledge, meet their needs and improve their profitability.

VISION

Our services include ground water resource assessment; mine dewatering design and application; ground water supply; pollution control and remediation.

Emphasis is on using tried and tested techniques developed by KLMCS, so as to reduce costs and improve ground water control and utilization. Techniques developed on mining projects are transferred to development projects in remote areas. KLMCS recognizes the need to achieve a balance between industrial development and environmental responsibility. Our vision is to continue serving the mining, energy and industrial sector, providing feasible, environmentally sound solutions and expanding our services to include the implementation of remedial techniques as required.

Case Studies

A ground water investigation was done to discover a new aquifer for the supply of 12 Mm³/yr of water for new and existing mines in Botswana. A radius of 50km around the central mine was mapped 
and trial pumped. The aquifer now has 7 wellfields and has supplied around 12 Mm³/yr of good quality water for 30 years.

Water Supply for Three mines in Botswana (De Beers)

A ground water investigation was done to discover a new aquifer for the supply of 12 Mm³/yr of water for new and existing mines in Botswana. A radius of 50km around the central mine was mapped and trial pumped. The aquifer now has 7 wellfields and has supplied around 12 Mm³/yr of good quality water for 30 years.
The mine occupies an arid area (rainfall is 2mm/yr) but penetrates a limestone aquifer. KLMCS did geological mapping and hydrogeological characterisation using test pumping boreholes and establishing a monitoring network. Numerical modelling predicted inflows of over 100 000 m³/yr with a required dewatering rate of 50m per quarter to match the mine schedule. A combined in-pit and pit perimeter dewatering ring was designed to meet the mine’s cash flow.

Mine dewatering design for lead/zinc mine Namibia

The mine occupies an arid area (rainfall is 2mm/yr) but penetrates a limestone aquifer. KLMCS did geological mapping and hydrogeological characterisation using test pumping boreholes and establishing a monitoring network. Numerical modelling predicted inflows of over 100 000 m³/yr with a required dewatering rate of 50m per quarter to match the mine schedule. A combined in-pit and pit perimeter dewatering ring was designed to meet the mine’s cash flow.
When approached for advice the pits were under water and losing US$500k/day.  KLMCS identified the sources of the water and adapted the management strategy to ensure the water was intercepted before reaching the pit and that water levels were kept 9m below pit bottom at all times.  A water monitoring network was designed, telemetised and dash boarded to ensure accurate water control.  Once the first mine was changed to meet the new strategy KLMCS worked on the groups other 12 mines in the area and provided training in water management strategy. All had similar successes.

The gold coast receives cyclonic rainfall events. The dates and volumes of incoming rainfall can be predicted.  KLMCS designed the ground water and storm water dam monitoring network. This was dash boarded and is used to predict the impact of rainfall events.  If the ground water and dam levels are low, then the risk of flooding from a storm event is low. This signals a green risk level and no action is required.  If the levels are high (above a designated target level) then the mine is warned with code red and the equipment is moved from the pits before the storm event.

KLMCS are the world leaders in block cave dewatering design.  A ten-year research programme led to an accurate dewatering design and the installation of a monitoring system to pre-warn of mud rushes.
The mine was dewatered from 650m underground to 1km using 7 large diameter boreholes drilled with hydraulic raise bore drilling technology. The rig was designed specifically for the cage and tunnel dimensions.  A monitoring network was installed using automatic water pressure recorders in dedicated core holes located in dolomite compartments.

Working with the geotechnical teams of the group a slope dewatering and depressurisation system was designed to reduce water pressures in the high walls.  This reduction in pressure allowed steepening of the high walls with reduced waste stripping and increased profitability.
