INCORPORATING MEASURES TO REDUCE GROUND VIBRATION PRODUCED BY BLASTING FOR QUARRY SAFETY MANAGEMENT: A CASE STUDY

Therefore 15experimental bench blasts are performed at Wahola limestone quarry with different explosive ratios and drilling parameters to study the results of ground vibration. The objective of this study is to control ground vibration for quarry safety management. During this study ground vibration of experimental blasts is recorded to study their relation with quantity of explosives, ratios of explosives and drilling parameters. To achieve this objective, data is carefully checked and recorded for all important parameters of experimental blasts. Ground vibration level for each blast is recorded separately by using micro mate. On the basis of results of these experimental blasts, new blasting parameters are suggested to control environmental hazards. Explosive for experimental blast was calculated very carefully. All possible hazards were identified and mitigation measures were taken before charging of explosive.
