Abstract: Mines are looking for efficient ways to improve their day-by-day operations while enhancing safety. When it comes to instrumentation and monitoring, the solution should be simple to use, easily installed and economical. Good monitoring practices should minimise personnel effort by promoting a more intelligent use of technology.
In this context, this paper presents the xCell Cyclops that Sandvik has recently developed. With the xCell Cyclops monitoring system, it is possible to get a real-time flow of convergence measurement data delivered straight into the cloud-based application. The xCell Cyclops is directly mounted to MD, MDX and Kinloc bolts or through use of low-profile adaptors any standard threaded bolt. Once installed, the xCell Cyclops continuously measures the distance from one side of the excavation to the other using precision laser technology. With wi-fi connectivity, the data is instantly available in the web and iOS interface. If wi-fi is not available, the xCell Professor, a Bluetooth low energy gateway, is mounted on already existing vehicles for drive-by data collection.
When compared to current measuring methods, the xCell Cyclops allows for a deeper understanding of rock mass behaviour by providing timely and continuous readings collected with minimum effort by site personnel. This technology leads to a safer, more sustainable work environment, can assist in ground support design, and improve the cost efficiency of ground support by optimising ground support utilisation.
