This article examines how accurately mapping artisanal mining areas will enable the enforcement of mineral rights and the regulation of the informal mining sector as well as assisting in the management of scarce and valuable resources… (more)

A unique approach to LV switchgear protection and the process of transitioning this concept to a real-world application. In low-voltage (LV) power systems (600 V and below), a network of communicating devices can provide supervisory control functions, gather substation electrical data and report event status to a central control computer… (more)

When constructing Stockholm’s City Line – northern Europe’s biggest infrastructure project – geologists used Topcon’s Imaging Station to check for cracks in the rock walls after the blasts. Every day, throughout the year, some 450 000 travellers journey to or from Scandinavia’s biggest railway station, Stockholm Central… (more)

Assessment and monitoring of erosion has with the advent of geospatial techniques become more accurate, affordable and less time consuming. This study was based on the use of GIS, remote sensing and field surveys techniques to identify gully erosion within the Zhulubemeso-catchment of the Limpopo Basin in Zimbabwe… (more)

Monitoring poverty levels enables government and the private sector to make more informed decisions about where social development funds should be invested. This research reveals that poverty levels are declining in some rural areas and rising in several urbanised local municipalities… (more)

Contractors are frequently exposed to fluctuations in material prices and are at a financial risk when appropriate provision for escalation in material prices is not made. It is for this reason that the Contract Price Adjustments Provision (CPAP) indices are compiled for use by contractors who require a simple and agreed escalation formula to provide reasonable reimbursements for price fluctuation… (more)

Much of the agriculture in the American West depends on underground water systems that need to be carefully monitored to avoid overuse. Traditional data about aquifers are sparse and expensive to obtain. Until now, crops growing above the aquifer prevented satellite-based radar from “seeing” under the surface. But Stanford researchers have found a way around the plant problem… (more)

With the advent of technological advances and the movement to proactive maintenance, the official death knoll has been served on reactive maintenance and crisis management. Although reactive maintenance has served the organization for the last several decades, it has left behind virtually no written documentation of any of the past work. Interestingly, it has also been discovered that quite often several hundred thousand dollars worth of spare parts inventory is stashed away in cubby holes… (more)

Monitoring and understanding coastal processes is important for the Netherlands since the most densely populated areas are situated directly behind the coastal defense. Traditionally, bathymetric changes are monitored at annual intervals, although nowadays it is understood that most dramatic changes are related to high-energy events like storms… (more)

The South African National Roads Agency Limited (SANRAL) is responsible for planning, designing, constructing, operating, rehabilitating and maintaining South Africa’s national roads. This article outlines the technologies involved in monitoring the condition of over 16 000 km of South Africa’s national roads… (more)

In a world first, GeoSystems Africa recently supplied and installed a Leica GeoMoS system at Goldfield’s Driefontein Mine, 2300 m below surface. According to Michael Rutschmann, of Leica Geosystems in Switzerland, this is the first installation at this type of underground mine in the world, and he is very pleased that their product could be utilised in this way to provide peace of mind to the Driefontein management… (more)

Subsidence-induced fault reactivation may cause moderate to severe damage to concrete foundations, houses, buildings, and underground services, as well as damage to agricultural land through disruption of drainage and alteration of ground gradient. Monitoring and analysing the spatial distribution of the deformed surface may be helpful for land-use planning, land reclamation or remediation… (more)

Most of you have seen rally cars racing at high speed on country roads with clouds of dust, through forests, rivers and across deserts.  Ever wonder how the timing, route monitoring and safety tracking are done?… (more)

After several unseasonably heavy rainstorms, a 105 hectare landslide occurred at Trapper Coal Mine in northwest Colorado.  In some areas, the slide displaced ground more than 122 m. Several mineable coal seams are located beneath the slide zone. If the slide were to reactivate, by natural catalysts and/or mining activity, loss of life and equipment would be devastating… (more)

Mine motion monitoringWhether underground or at the surface, unanticipated earth movement can pose particularly hazardous conditions on mines. Risks include the endangerment of lives, destruction of property and damage to valuable, specialised equipment. Today’s open-pit mines are far deeper than before. Because rock mass strength at these vast scales is difficult to evaluate, massive slope failure can occur with little warning. Monitoring therefore plays a critical role in early detection, minimising risk and safeguarding resources… (more)
