• W141615167 abstract "An ever-present challenge at most active mining operations is controlling blastinduceddamage beyond design limits. Implementing more effective wall control duringblasting activities requires (1) understanding the damage mechanisms involved and (2)reasonably predicting the extent of blast-induced damage. While a common consensus onblast damage mechanisms in rock exists within the scientific community, there is muchwork to be done in the area of predicting overbreak.A new method was developed for observing near-field fracturing with aborescope. A field test was conducted in which a confined explosive charge wasdetonated in a body of competent rhyolite rock. Three instrumented monitoring holesfilled with quick-setting cement were positioned in close proximity to the blasthole.Vibration transducers were secured downhole and on the surface to measure near-fieldvibrations. Clear acrylic tubing was positioned downhole and a borescope was loweredthrough it to view fractures in the grout. Thin, two-conductor, twisted wires were placeddownhole and analyzed using a time-domain reflectometer (TDR) to assess rockdisplacement.Fracturing in the grout was easily observed with the borescope up to 3.78 m (12.4ft) from the blasthole, with moderate fracturing visible up to 2.10 m (6.9 ft). Measuredpeak particle velocities (PPV) at these distances were 310 mm/s (12.2 in./s) and 1,490mm/s (58.5 in./s), respectively, although no fracturing was observed near the depth of thevibration transducers located 3.78 m (12.4 ft) from the blasthole. TDR readings weredifficult to interpret but indicated rock displacement in two of the monitoring holes.Three methods were used to predict the radial extent of tensile damage around theblasthole: a modified Holmberg-Persson (HP) model, a shockwave transfer (SWT)model, and a dynamic finite element simulation using ANSYS AutodynTM. The extent ofdamage predicted by the HP and SWT models is similar to field measurements whenusing static material properties of the rock, but is underestimated using dynamic materialproperties. The Autodyn™ model significantly overpredicted the region of damage butrealistically simulated the zones of crushing and radial cracking. Calibration of materialparameters for the AutodynTM model would be needed to yield more accurate results." @default.
