Different sensors, from extensometers and inclinometers to fiber optics and deformation gauges, will be installed. A multi-physical assessment of the fracture network around the intersection will lead to its...

... working conditions. Ground squeezing rates at Turquoise Ridge have been monitored with cross drift extensometers over the last 12 years and, more recently, with MPBXs and smart cables. Squeezing rates have ranged from 1 inch per year to over 1 inch per week, depending on ground conditions and mining...
