Productivity increase at drilling and hole alignment

Tracked down the hole (DTH) machine Electric/ Diesel (MFFR) - Zenith

Fravizel’s mission is to endue quarries with solutions that allow the productivity increase. Between the phases necessary to the stone extraction (figure 1), Fravizel equipment’s participate in every quarry phases.

At the drilling phase (the first step in the extraction process), we reach that goal with 90,4% of productivity gain.

At the drilling operation, this machine allows to:

• Automotive as it does not depend on other machines to position itself;

• Radio controlled (remote);

• Time decreasing to movement and commissioning, which leads to a which leads to a reduction in the time between holes;

• Flexibility, do all positions do drill (vertical, horizontal and inclined);

• Hydraulic levelling allows you to adjust drilling start faster

• Reduces the height of the hole to the floor, which increases the volume of explored stone, decreasing the gap between floors (levels) and maximizes the following operations

• 2000mm drilling stroke (alternatives are mostly 1200 or 1500mm). Which leads to a 40% efficiency (change rods less and drill more).

• The speed of commissioning / drilling deletes the necessity to make very long horizontal holes, with immediate advantages in the success in the triangulation hole to pass the Diamond cable (the bigger the distance, the bigger the probability to miss the triangulation point).

• Collection of digital productivity data;

• This way, the entire drilling operation might have a significant gain of productivity (90,4%) which will allow always having holes waiting for the cut of the Diamond wire for the bench processing (bench).These values do not take into account other factors that directly influence the gain of productivity, such as human and materials resources.

It’s essential the growing evolution of techniques and technologies that provide the industry with instruments aiming reducing the extraction times and, this way, contributing for a higher profitability of the raw material, reducing its waste. It’s also important to have less energy, water and fuel consumption and more safety conditions for workers.
