Geologists Prepare to Drill Into Ancient Antarctic Lake | Rock Drill Bit Grinding Machine

After stopping at an oil well that had defied conventional drills, the men ordered field hands away and secretly brought out the bit and attached it to the pipe stem of the rotary rig. For the next 11 hours, the bit bored through 14 feet of solid rock, “a feat so miraculous for the time that drillers dubbed the mysterious device the “rock eater.”

Epiroc evolved from the global split in January 2018 of Atlas Copco into two separate companies and comprises the Mining & Rock Excavation Technique Business Area and Construction Tools division to focus on the mining and civil engineering sectors. The industrial businesses remain with Atlas Copco. Epiroc Business Line Manager, Surface & Exploration Drilling (SED), Hedley Birnie, explains how the business partnership with Booysen Bore started: “In 1999, SED Area Sales Manager for Atlas Copco, Cobus Engelbrecht, conducted the very first trial with a ROC L8 MK I test machine for Booysen Bore at Beeshoek Mine.

As far out as monster trucks look – with their full tube chassis and four-wheel steering – it’s not hard to take a wild guess at the evolutionary steps that brought it to the machine we know it as today. Essentially starting out as a guy wanting to see if he could run over a set of blown out car bodies in a field, the sport feverishly took off with a warm and enthusiastic public reception similar to NASCAR. There was just something transfixing about watching a motor and chassis push around 3,600lbs of rubber. A typical snapshot of the mechanical madness responsible for the “thunder within” takes the form of a 540cid, supercharged race motor; centrally located to balance out the truck and lower the center of gravity. Many of these monsters blow all of that torque through a two-speed Powerglide transmission (heavily-modified, of course).

there are, in the opinion of Kramp cart Builder, for two reasons. A it was the good economic Situation of Germany, like you said. Another the various political traditions. Demonstrations would take in the political culture of France in a more important place.

- A total of 135 veins within 61 vein packages were individually modelled as opposed to the previous approach of applying geostatistics to 56 grouped vein packages, and thereby provided an upgraded confidence in the vein packages/domain boundaries.

The machine was the first drill rig capable of drilling at an angle making it ideally suited for block drilling.  Booysen Bore was so impressed with the ROC L8’s performance that they decided to keep the machine for blast-hole drilling on the mine and to systematically replace all their non-Atlas Copco drill rigs at the end of their life cycle with ROC L8s.”

Club conundrum: Filling Louis’ Pica-hole. King Louis is no longer swinging around the Premiership. Picamoles jumped ship moving to Montpellier in the summer. The Saints have plateaued and then fallen massively since they won the title in 2014, and losing their star No 8 won’t help the slide. Someone must step up to fill the considerable hole he has left.

AISC amounted to $819/oz, well below the guided $860-900/oz range as a portion of the planned waste capitalization was shifted to 2019 and more oxide material was processed compared to the initial plan.

I also like the Topps 60 inserts. The foil logo gives the cards a premium look and all the different designs from previous years offer a lot of variety.
