SMART geotechnical instruments from Mine Design Technologies (MDT), vibrating wire based instruments from many manufacturers, and most recently microseismic sensors embedded in the toe of MDT SMART instruments can now be monitored using the MineHop battery-powered wireless mesh network. This paper will discuss the different applications of the MineHop technology, the ease of installation and maintenance, specifications, and case studies including examples of typical installations.
