Maintain optimal material fragmentation to maintain efficiency across the mining value chain

A fragmentation strategy for drilling and blasting directly affects the efficiency of subsequent processes such as loading, hauling, and processing. Many factors need to be accounted for when developing this strategy to ensure mining efficiency but also to meet regulatory compliance with evolving environmental and safety regulations.

For instance, geological formations can vary significantly in terms of density, fault lines, ore body and vein profiles. A one, or two, size-fits-all strategy leads to inconsistent fragmentation, increased blasting costs and sub-par mine operations. Achieving the correct energy distribution in the blast is crucial. Poor distribution leads to inconsistent fragmentation and poor benches for drills and excavators. Furthermore, over-break leads to dilution and excessive powder factors – impacting mining economics and resource recovery.

Mining operations also often take place near populated areas, sensitive ecosystems, or infrastructure. Minimizing ground vibration, noise, and air blast overpressure to prevent damage and complaints requires careful planning and is critical to securing future investment prospects.

Key Client Challenges:

  1. What are the geological compositions we should factor into our blasting and fragmentation strategy?
  2. What is the optimal fragmentation size for efficient handling, processing and ore recovery?
  3. What blast design parameters should be used such as drill hole diameter, spacing, and burden to optimize energy distribution and fragmentation outcomes?
  4. How can vibration and air blast effects be minimized to mitigate the potential impacts of blasting on nearby communities, infrastructure, and the environment?
  5. What safety measures should be implemented to reduce the risk of flyrock, misfires, and other hazards associated with blasting operations?
  6. What data monitoring and collection methods can we use for post-blast analysis to ensure optimal fragmentation?

Real-time monitoring of blasts and the ability to make adjustments based on initial results are crucial for optimizing fragmentation. However, this requires well-established monitoring systems and quick decision-making processes.

While incorporating advanced technologies like computer simulations, laser profiling, and real-time monitoring systems can enhance fragmentation design accuracy, adopting and integrating these technologies can present its own challenges for mining companies. Balancing the costs associated with these technologies as well as investing in the talent pool and training to effectively utilize them will require a comprehensive strategy.
