Engineering Drilling Rig Coring

When information regarding the rock at any given site is desired rock coring can be conducted in order to evaluate the type, quality, soundness, strength and other properties of the rock. Rock coring is generally accomplished with a diamond tip rock core barrel attached to a drill rig. The coring recovers a. . The easiest way to characterize the amount of material recovered during rock coring is to calculate “core recovery” as the amount (i.e. length) of material divided by the total length of. . Rock Quality Designation (RQD) (ASTM D6032) is a modified core recovery percentage in which the lengths of all sound rock core. .
