Slope stability accidents are one of the leading causes of fatalities in surface mining operations. These accidents may endanger lives, demolish equipment, or destroy property. Unanticipated movement of any amount of rock may cause severe disruptions to mining operations, pose major safety concerns, or contribute to large financial losses for companies

Slope stability monitoring installations are thus essential for safe and efficient mining operations. The detection of the onset of slope movements, the rate of movement and the associated rate of increase of the movement is required so that potential slope failure indicators may be identified.

Monitoring provides the information needed to support a safe working environment and economic and efficient mining operations whilst mitigating the associated risk of open pit mining in a steep slope environment.

The importance of a well planned monitoring installation as an essential component of the maintenance and operation of a dam, particularly in an aging structure where early warning signs of failure may be detected, is widely accepted and in many countries, enforced by legislation.

Wall deflection, settlement, water seepage, the diurnal and seasonal changes in reservoir levels, seismic activity and the aging of the structure all affect the health of the dam. Changes in the behavioral characteristics of the structure may be indicative of impending dam failure and it is the primary goal of the monitoring system to detect such changes.

Catastrophic dam failure through the uncontrolled release of the impoundment will threaten life and property downstream. The safe functioning of a dam is an important matter of economic benefit and public safety.

Comprehensive Monitoring

“With Trimble recorders, sensors and monitoring software, we now have greater confidence that we can spot any unexpected changes to the dam infrastructure and we can take steps to remediate issues to keep the dam functioning at optimal levels.” 

“Working with Trimble’s automated, real-time geodetic GNSS monitoring data, combined with automated water level readings, has enabled us to establish a more complete and more accurate method for monitoring movement, reservoir crest levels and possible swelling of the Victoria Dam.
