Diamec U6 core drilling rig successfully created a new record of drilling efficiency
Yunnan Tin Group (Holdings) limited liability company under the banner of the Datun tin respectively in May 2013 and February 2014 has introduced a Atlas Diamec U4 PHC Copco (hereinafter referred to as "U4") and a Diamec U6 DH PHC (hereinafter referred to as "U6") tunnel full hydraulic core drill machine, and thus record the tunnel full hydraulic core drilling drilling efficiency in the new record Yunnan tin group.
Old mines face new challenges
Datun tin is a non-ferrous metal mines have more than 50 years of mining history, metal production and tin tin ore production per year were 2 million tons and 12 thousand tons, mainly by sublevel open stoping with subsequent filling mining. In the entire industry is in the background of modernization and upgrading, Datun tin made a decisive introduction of new technology and new equipment, the use of Atlas U4 and U6 Copco tunnel full hydraulic core drilling rig as improving drilling efficiency, build a modern mine's Secret weapon.
Advanced equipment with half the effort
According to the Datun tin equipment energy director Gu Guang introduced, the smaller the U4 drilling rig, the main work in the 5 x 6 metres on the working surface, drilling depth of 280 meters (the final hole size is NQ), the operation time is 15 hours a day, the highest single month footage of 1036 meters, the average footage is 900 meters / month that is equivalent to 1.5 times the ordinary rig, after being put into operation a tunnel full hydraulic core drilling drilling efficiency in the new record of Yunnan Tin group.

After the introduction of the U6 rig, the drilling efficiency record of Yunnan Tin Group full hydraulic core drilling rig has been refreshed again. Compared with the U4 U6 drilling rig, the larger, more power, working mainly in the 6 x 8 metres on the working surface, drilling depth of 618 meters (the final hole size is NQ, drilling rig capacity is N specification 900 meters), the operation time is 15 hours a day, the highest single month footage 1390 meters, the average footage is 1030 meters / month, compared with the ordinary drill footage 600 meters / month, efficiency increased by 1 times.
When it comes to the device's performance, guzhuren said: "although the U4 and U6 drill size and power are different, but they all have a common characteristic, is the production of high efficiency, can be in each class of operators of exploration rig reduced by 3 to 2 people, it is very important to the role of our iede play."
The Atlas Copco mine and rock excavation technology department provides customers with comprehensive drilling and rock excavation equipment, all kinds of related consumables and services through the global network. Providing sustainable productivity for open and underground mining, infrastructure, civil engineering, water well drilling and geotechnical engineering applications.
