Delve Mining Solutions

Drill & Blast Optimisation

On average, it takes three to five years of effort and expense to reach a new stope. Therefore, when it comes to extracting ore, the drill & blast designs used must be the safest and most effective possible to ensure no effort is wasted.

Delve Mining Solutions can offer;

  • Comprehensive analysis of existing drill & blast procedures
  • Specialist guidance to optimise your production output
  • On-going monitoring of your production cycle

Take a look at our Dilution & Recovery Value Calculator to see how much value your site could gain from optimising your Drill & Blast practices.

Drill & Blast Optimisation

A four-dimensional process

Whether you aim to reduce unplanned dilution or increase fragmentation, Delve Mining Solutions can review and adjust your existing stope design parameters and tailor them to achieve a desired output.

Drill & blast engineering is a four-dimensional process; however, we see many Engineers designing simply in one or two dimensions which can result in poor stope performance.

Common problems

Overbreak, underbreak and recovery are factors that are influenced by your drill & blast procedures, Mining Engineers, equipment parameters and operators.

Factors your Engineers have control over, such as orientation, hole length, drill hole diameter, dump angle, rotation angle & matching drill rig capabilities to the stope design.

If you are experiencing any of the factors listed, contact us today.

If these factors are not harmonious, then the following can occur;

  • Bridged firings
  • Frozen ground
  • Powder factors may exceed optimum figures
  • Rough hanging walls
  • Holes not drilled to design, missing holes or short holes
  • Drill holes not loaded
  • Poor record keeping and imperfect reconciliation of parameters and performance may result in fragmented data, tedious data collation and analysis, and in effective collaboration
