How different is the idea of a smart city from JNNURM? Experts say JNNURM was focused on creating city-wide …

After several years of experiments, Hughes and Sharp introduced the novel drill bit suited for deep boring through medium and hard rock, according to the American Society of Mechanical Engineers.

Biographers note that about the time Sharp and Hughes were developing their bit, Hughes had a chance meeting in Louisiana with another inventor trying to improve drilling technology.

- Ore mined increased due to greater extraction at the South Pit as less stripping was necessary. Waste extraction efforts continued in the West pit, resulting in an increase in the overall strip ratio.

The great majority of borehole sites that extend down to 200 metres and 300 metres in depth revealed rise in core temperature. Depths of the boreholes ranged from 150 to 1,522 metres.

It comes as the company is supplying around 25 per cent more water than usual to keep pace with a surge in demand caused by the hot weather.

Club conundrum: Are they better than Irish? That is pretty much the test this year. Last year they were better than Bristol, the year before they were better than Irish and Newcastle, and stayed up.

Specific gravities of 1.66 g/cm3 for the Saprolite, 2.19 g/cm3 Saprock and 2.69 g/cm3 Fresh Rock at Kalana have been used derived from results of the Archimedes Method. Specific gravities of 1.70 g/cm3 for the Mottled Zone, 1.76 g/cm3 Saprolite, 2.09 g/cm3 Saprock and 2.64 g/cm3 Fresh Rock at Kalanako have been used.

When founded in 1977 by Hennie Booysen, Booysen Bore focussed mainly on exploration drilling. In 1990 the family business expanded its services to blast-hole drilling and continued to grow into the successful business and major role player in the Northern Cape’s mining environment that it is today. Part of the Mogs (Mineral, Oil & Gas Services) Group, Booysen Bore’s offering includes Down-The-Hole (DTH), percussion, exploration and core drilling as well as in-pit de-watering drilling services.

Parallels are plentiful and revolve largely around color: Gold (#/2015), BCA Pink (#/499), STS Camo (#/399), Platinum (1/1) and Printing Plates. Exclusive to hobby and jumbo, 60th Anniversary parallels come with a foil stamp of the celebratory logo. They are numbered, appropriately enough, to 60.
