Blasting is the predominant rock excavation technique in tunnel/drifts. During blasting, the uncontrolled shock wave movement caused damage to the surrounding rock strata. This results into additional support cost and time over run to complete the project. The available controlled blasting techniques are costly and time consuming and hence not popular. Thus, vibration based damage control technique has more applicability and popular world-wide. This book present the a strong review of the causes of rock damage and the role of its influencing parameters on the extent of rock ...
