Core sampleWikipedia

A core sample is a cylindrical section of (usually) a naturally occurring substance. Most core samples are obtained by drilling with special drills into the substance, for example sediment or rock, with a hollow steel tube called a core drill.The hole made for the core sample is called the “core bowling”.

Laboratory Methods of Sample Preparation

Sample preparation method and Laboratory sampling procedures involve either: Coning and Quartering; or Riffling Method. Coning and Quartering for sample preparation techniques/method The method which is used for sampling large quantities of material say 20kg, consists of pouring or forming the material into a conical heap upon a solid surface (e.g. a steel plate) and relying on radial symmetry .

This rock core depth should be followed if rock is encountered within 1 m (3 ft) of pavement subgrade level, and could be reduced if rock is located at greater depths. Cores should be used to identify the rock, determine the quality of the rock, and evaluate its durability.

The pullout capacity of the cone is a function of the weight of the cone and the shear resistance of the rock along the surface of the cone. Rock anchors are typically designed with embedments deep enough to ensure ductile failure of the steel bar.


2. Rock units with at least 3 UCS and 3 PLT results were selected for inclusion in the data base. 3. The mean UCS, mean Is 50, the standard deviations, and the CI95 were calculated for each rock unit. The samples were also categorized into rock type based on the geologic description. These rock types correspond to the Ferm Classification numbers.
