Petrochemicals (and its respective industry) is truly a fascinating subject. However, although there is much to discus in terms of wealth and fortune, there is also the environmental aspect to take into consideration.

When it comes to petrochemical industries throughout the world there are always issues to take into consideration that are influenced and affected by a number of variables – be it of an environmental or economical nature.

MMPR spoke to PetroSA’s chief economist to get an illustrated story about how the situation fares, not only in South Africa but around the world.

As a global society we have come a long way in improving the industry in such a way that it has become more efficient, but we have also still got a very long way to go, as entire communities are often at risk to the whole industrial process of it all.

If we could find a way to exploit resources underground without putting human lives or the environment at risk then everyone wins.

The face of drilling today

The dimensions involved in today’s drilling solutions need to be explored for a better understanding of what the mining industry should expect. MMPR spoke to different experts involved
in various drilling solutions for the mining industry to illustrate how the situation fares. Otto Coetzer, Vula Drilling Director: Product Development shared some insight, “We manufacture drilling consumables that we use for underground drilling. There are two specific types of drilling applications:

Tooling in the mining industry is an extremely broad topic as there are thousands of different kinds of tools.
The Oxford Dictionary describes a tool as an implement used to carry out a particular function, or a thing used to help perform a job.

SOME TRENDS
Element 6, which has strong roots in the South African diamond industry, dating back some 60 years, provides a good reference point for some of the tools that are being used in the mining sector today.

  • Hard rock – drilling is typically required in exploratory and blasting holes, so the choice of inserts to mount into drill tools should be taken into consideration.
  • Soft rock – a range of hard wearing tungsten carbide products and synthetic diamond picks is believed to offer overwhelming benefits to the industry.
  • Tunnelling – round shank picks with a diversity of head designs and retainer systems are needed for this specific application, and inserts can be customised for specific requirements. Drill bits are used for roof bolting, particularly those equipped with tungsten carbide or polycrystalline diamond inserts to suit the rock conditions.


Such a brief overview already shows some key concepts that emerge:

  • Synthetic diamond – working face material in exploratory and blast hole drilling through the world’s hardest formations, which exist in a range of different sizes, strengths, and coatings.
  • Polycrystalline diamond – can be mounted on drills and picks to increase penetration rates and increase longevity of performance life.
  • Carbide tungsten – tough, hard and economical with good wear resistance even at high temperatures.
