Mining sites require continuous monitoring and effective alarm systems to preserve the safety of the site and mitigate risk to mining operations and assets. Monitoring provides the information needed to support a safe working environment and efficient mining operations while mitigating the associated risk. High walls, excavated faces and potentially unstable slopes can create hazardous work environments. Vibrations and movements of mine infrastructure and assets caused by mining activities such as blasting, drilling, or excavating can be detected by the sensors. Another monitoring objective is early detection of potential failure of stockpiles and tailings dams which may dramatically impact short and long-term mining operations.

  • Monitoring high wall stability
  • Monitoring tailings dams integrity
  • Multi-sensor support

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.

  • Stability assessment in seismic areas
  • Long and short term analysis of structural behavior
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.
