Abstract
Existing instrumentation and implementation of a more comprehensive stability monitoring strategy is discussed in detail. The stability in this case is of particular importance, as the site is close to community infrastructure, and consequently, community residents. This paper addresses the benefits of the selected monitoring system and each system component, and includes the challenges resulting from the geographical location, rock mass conditions, and maintenance due to the remoteness of the site. There were no local employees available to address the monitoring system health.
The site has not experienced any documented instability since the mine had closed, based on almost three decades of shallow monitoring and site observations. The installation of monitoring systems is usually, targeted at monitoring movement. However, for this site, instability and ground movement were not expected, leading to monitoring focusing on system health and the detection of potential movement. The lack of employees on site also made the health and functionality of the monitoring system critical as there was a desire to prevent frequent system maintenance and troubleshooting.
