With the world of drilling demanding higher production rates, lower overall cost per meter and greater efficiency Mincon stepped up to the challenge with the MP40MQ.
The target is to achieve higher penetration rate and longer internal component life, raising production and lowering cost per meter, this will be achieved by excellent design and manufacture of Mincon tools along with expert advice and guidance and a continued improvement program.
The following three case studies prove this Hammer truly is the “The Driller’s Choice Worldwide”
Dubai (on going trial)
August 2020 Mincon deployed the MP40MQ after the Driller was experiencing high cost per meter and low production from their current supplier.
Current supplier
DR43 Epiroc D55 an average penetration rate of 0.79 meters per minute was recorded.
Feed: 75 Bar
Rotation: 55 Bar
Air Pressure: 24 Bar
Mincon MP40MQ
DR47 Epiroc D50 an average penetration rate of 0.95 meters per minute was recorded.
Feed: 85 Bar
Rotation: 35 Bar
Air Pressure: 22 Bar
This is an increase of 20% penetration rate, the MP40MQ was then put on DR43 the air pressure increased to 30 Bar and an average penetration rate of 1.1 meters per min was achieved, giving an increase of 40%.
The customer also reported changing failed major internal parts 3-4 times in the hammers life of 20,000 metres, the MP40MQ Internals are currently at over 5,000 meters and still going strong.
Senegal – Pre-splitting holes – 20 m @12 degrees January 2020
Mincon deployed the MP40MQ after experiencing broken pistons and broken strike face on bits. Not only has this problem now been totally eradicated but the penetration rate has improved from 16 meters per hour to 18 meters per hour that is an increase in penetration of over 12%.
The customer was extremely impressed with the results and now the MP40MQ is the only 4” hammer they purchase.
UK (ongoing trial)
July 2020 Mincon deployed the MP40MQ as an alternative to the 4HRTD. We compared both hammers side by side on 2 Epiroc D55’s The rock here is a medium to hard granite that is extremely abrasive, the drilling is very challenging with up to 7 meters of broken rock at the start of the hole and a high ingress of water.
This type of drilling can be very punishing on the rock tools causing a high amount of back hammering/free hammering whilst try to get through the broken ground, normally resulting in shanked bits and broken pistons.
When using the MP40MQ for over 20,000 meters we have not experienced any breaking of internal components.
As can be seen in the table opposite the MP40MQ has achieved 12% increase in penetration rate 11.5% decrease in litres of fuel per hour 8% decrease in engine load This is one of the MP40MQ pistons used in the UK trial at 10,304 meters, when compared to a new piston there has been zero OD wear and very minimal impact damage to the strike face.
This is the reason the hammer is still performing and consuming same amount of air as when new.
Conclusion
The MP40MQ has proved to be a high performing hammer in some very demanding drilling conditions.
Consistent high penetration rate
Reliable and robust internal components
Lower air consumption
Lower fuel usage
Lower engine load
It is important to note as this is a high performing hammer, drill parameters will need to be adjusted to suit increased penetration rate also ample amounts of high quality hammer is to be used, on all of the case studies feed pressure was increase by 10-20 Bar
Future
Mincon is currently running extensive trials on coated chucks as part of our continuous improvement program this is with a scope to improve overall hammer life by up to 40% in abrasive conditions.
Combined with high performance of the MP40MQ it will be “The Drillers Choice Worldwide.”
