Rock Drilling, Sampling Testing

 · ROCK SAMPLERS The samples obtained from rock drilling are known as "Rock Cores". Rock coring is the process in which a sampler consisting of a tube (core barrel) with the cutting bit at its lower end cuts an annular hole in a rock mass. Thereby creating a cylindrical or core of rock which is recovered in the core barrel. Core barrels does function of both drilling retaining the sample ...

SAMPLING TECHNIQUES

Composite Samples: A composite sample consists of small chips of uniform rock material collected over a large area (generally > across). These are the ideal "representative" samples. The procedure is to collect small pieces of rock over a large area (usually at least 10 feet across) and to make the sample as homogenous as possible.
