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.

因此，为探究地面振动效应，研究团队在瓦霍拉（Wahola）石灰岩采石场开展了15次不同炸药配比与钻孔参数的台阶爆破试验。本研究的核心目标为通过管控地面振动，实现采石场的安全管理。试验过程中，研究人员对各爆破试验的地面振动数据进行记录，以分析其与炸药使用量、炸药配比及钻孔参数之间的关联。为达成上述研究目标，研究人员对爆破试验的全部关键参数进行了严谨核查与记录。本次试验采用微型测振仪（micro mate）分别记录每次爆破的地面振动强度。基于本次爆破试验的结果，研究人员提出了可管控环境危害的新型爆破参数方案。本次试验所用炸药均经过精准核算；在装药作业实施前，研究团队已识别所有潜在危害，并落实了相应的风险缓解措施。
