Blasting Control in Mining for less Environmental Impact
Conventional method in mining is to use blasting for rock fragmentation. Impacts from blasting were sometimes reported, either fatally or non-fatally, for both surface and underground mining. Case experiences from around the world are needed to avoid those unwanted circumstances.
A number of case experiences are demonstrated for both surface and underground excavations according to various parameters, e.g. explosive charge, blasting pattern (spacing, burden, stemming, sub drilling), delay, etc.
Various monitoring techniques are also illustrated to measure or monitor the effects from blasting.
