Percussive Assisted Rotary Drilling – PARD
Simply defined, PARD is the next viable choice to drilling faster and more efficiently. Other benefits include straighter drill holes, easier hole collaring and increased productivity. This is achieved through increased penetration rates which lower the total cost of drilling (TCD).
Adapted to standard blasthole drill rigs
The system can be adapted to standard blasthole drill rigs and drill strings. The result? A combination of percussive power and rotational force that increases ROP significantly.
Easy to install and operate
Installing our PARD system is easily adaptable and reversable to existing drilling operations. The simple installation means adding an oiler and a starter drill pipe. Once the correct starter drill pipe, hammer and bit are in place, it's a matter of simply adjusting the airflow to set the frequency and you are ready to drill. It was also discovered that the PARD system makes collaring easier and drilling more stable!
The PARD hammer has been developed to increase rotary drilling productivity. This low impact hammer has a special short stroke lightweight piston.
A synergy combination is formed between the tuned hammer and the rotary forces which results in the PARD system creating a higher level of energy than a DTH hammer or rotary power alone. And that means a lot more holes per shift.
PARD tricone bits are designed to retain the same service life as standard tricone bits while increasing ROP. This has been achieved by redesigning the PARD tricone bits to withstand additional stresses and strains. All this adds up to greater productivity and lower cost per foot drilled.
