Undoubtedly, the biggest challenge of deep level mining is providing a safe environment for miners. Today, gold and platinum mines descend as far as 5km below surface in some cases. In this extreme environment, virgin rock temperatures often exceed 60°C, requiring sophisticated cooling methods and equipment to reduce temperatures to safe levels for miners to work in. Due to the ...

The height of surface profile has been shown to be a factor in the performance of various coatings applied to steel. For this reason, surface profile should be measured prior to coating application to ensure that it meets that specified. The instruments described are readily portable and sufficiently sturdy for use in the field. Note 1—Optical microscope methods serve as a referee ...

It is understood that the policy package is to be adopted by the European Commission (EC) on 18 June. The measures will focus on food and construction waste and will look to EU commitments beyond the current 2020 targets, which instruct member states to recycle 50% of their municipal solid waste and 70% of construction waste. Speaking at Brussels’ Green Week conference, environment ...

Fumed Silica has a bulk density of around 30g/l, and a surface area of sometimes hundreds of square metres per gram. It is used as a thickening agent in everything from gel batteries to non-drip paint, as a light-scattering agent in cosmetics and a toothpaste abrasive. However, a material as light as this presents significant difficulties in bulk measurement. After a number of failed attempts, ...

Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions. Sea level rise in one of the major consequences of global warming, but it is much more difficult to ...

Many traditional methods for detecting airborne sources of contamination rely on the deposition on these materials on to a surface. For example, surface swabs might be taken, or bioaerosol sampling might be undertaken with a sampler that relies on the impact of biological particles on to a solid growth medium. “These methods are unable to deliver an accurate measurement of airborne ...
