Blast Influence

Influence of blasting operations on the surrounding environment is investigated. Investigate the related levels and possible influences of expected ground vibration, air blast, fly rock and noxious fumes on the area of 3500m surrounding the blast areas. The possible environmental or social impacts expected can be summarized in the following aspects:

  • Introduction
  • Background information of the proposed site
  • Mining operations and Blasting Operation Requirements
  • Effects of Blasting operations:
  • Ground vibration currently generated and expected from future blasting operations
  • Ground vibration prediction and modelling
  • Ground vibration limitations for structures
  • Ground vibration control
  • Ground vibration limitations with regards to human perceptions
  • Vibration impacts on productivity of farm animals (cattle, chickens, pigs, etc.)
  • Vibration impact on national and provincial roads
  • Vibration impact on communication towers and equipment in the area sensitive to vibration
  • Vibration will upset adjacent communities
  • Cracking of houses and consequent devaluation
  • Borehole collapse
  • Muddying and pollution of borehole water
  • Air blast currently generated and expected from future blasting operations
  • Air blast prediction and modelling
  • Air blast limitations on structures
  • Air blast limitations with regards to human perceptions
  • Air blast control
  • Fly rock causes
  • Fly rock predictions
  • Fly rock control
  • Impact of fly rock on road users
  • Noxious fumes causes
  • Noxious fumes control
  • Risk Assessment
  • Mitigations
  • Recommendations
  • General Safe Blasting Practices:
  • Current Status on Structures basic information
  • Monitoring
  • Additional actions required as identified or resulting from risk assessment
  • Conclusion
