At Platosa Mine in Mexico YieldPoint dExto’s were used to monitor the back during the recovery of pillars. According to Samuel Freitag, the lead author, when the work was presented at the CIM conference(2019):
‘YieldPoint’s high resolution extensometers allowed us to monitor very small deformations. At first I thought that deformations less than a few mm were just noise, but because they appeared on multiple instruments and were synchronized with blasts we began to recognize and benefit from the high precision of these instruments”.
Working with consultants and researchers for the Colorado School of Mines, the project team at the mine was able to safely and confidently remove targeted pillars.
