Stability of underground mine workings due to surface

The radial distance of ground vibration monitoring locations lies in between 20 m and 950 m. The PPVs recorded due to underground blasting ranges between 0.651 mm/s and 75.5 mm/s. The maximum PPV recorded from the production blast was 75.5 mm/s in sidewall with dominant peak frequency of 148 Hz at 59 m.
