Development of a Wireless Borehole Extensometer for Monitoring Convergence in Underground Mines
An extensometer has been developed to continuously monitor roof extension in underground mines. The extensometer is designed to be installed in the MSHA-mandated test holes in the roof and measures the displacement between an anchorage point at the top of the borehole and the hole in the roof of th...
