He and his team at WHOlives, a nonprofit group in South Jordan, have built 55 drills in 25 countries over the past six years. They brought a second drill into Renouard’s backyard for a demonstration to media on Friday.

The latest FlexiROC D65 crawler rig sets the benchmark in DTH drilling delivering a perfect balance between productivity and efficiency to provide a complete drilling solution. With hole diameters of between 110 – 203mm, this rugged multi-functional machine is able to handle a vast number of drilling angles, delivering straight, smooth holes with plenty of air to keep the hole clean for easy charging. The high efficiency of the DTH hammer relies on its precisely matched compressor capacity.

“Grass doesn’t grow in January,” said Aled. “All we can hope for now is that it starts raining, that the autumn is mild and that winter does not come early.

Washington — Workers who frequently drill concrete can experience reduced exposure to noise, silica dust and vibration if pneumatic rock drills are replaced with electric rotary hammer drills, according to researchers at the University of California, Berkeley.

It’s always worth being reminded that, in terms of sheer numbers and even mass, humanity is not the dominant form of life on Earth. Putting aside the somewhat bemusing question of whether viruses count as “life” for now, it’s safe to say that the microscopically small members of both the Bacteria and Archaea domains are everywhere.

The lower than expected performance is mainly attributable to sub-optimal underground equipment availability and associated maintenance costs.

Minding that, our products are constantly in a developing state, where we strive to increase penetration rates, decrease the use of lubricant oils and increase the working life on entire drill strings. This means less influence on the surrounding environment as well as more lucrative business opportunities for all our customers.

Water “megaprojects” are not unique to Israel. Humanity has long embraced what Peter Gleick, a scientist who co-founded the Pacific Institute, a think-tank in California, calls “the hard path” to solving its water problems: one that relies “almost exclusively on centralised infrastructure to capture, treat and deliver water supplies”. When water has been short, the solution has been to find a new source, or to bring it from somewhere else, in ancient times using large amounts of human labour.

She has two brothers, and in addition to her late father’s ties to the drilling industry, Vanessa has an aunt who owned and operated a blasting company.

This TV has a more entry-level panel, although we’ll save judgement for when we’ve actually had chance to see one in the flesh.
