Hand held rock drills

Modern handheld rock drills incorporate ergonomic designs with vibration-dampening technology, ensuring operator comfort during extended use. They typically offer variable speed controls and multiple drill bit compatibility, accommodating different rock formations and drilling requirements. [pdf]

Rock 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. . Earth Engineering conducts Rock Coring and Cone Penetrometer testing in PA, NJ, and Delaware. Contact one of our directors or project managers at any of our 4 locations to discuss. [pdf]

FAQS about Rock coring

What is rock coring?

Rock coring is generally accomplished with a diamond tip rock core barrel attached to a drill rig. The coring recovers a cylindrical core of rock by rotating and advancing the hollow core barrel. The rock samples provide significant information about the engineering nature of the rock formation.

How does rock coring work?

Rock coring collects bedrock cores for engineering and geological data. A diamond bit attached to a core barrel is lowered into the hole on the end of drill rods. Rock core samples are obtained by removing the inner barrel assembly from the core barrel of the drill rod using an overshot retriever.

What are the properties of rock coring?

Some important properties obtained from the rock coring are the type of rock, Rock Quality Designation (RQD), percent recovery and hardness/soundness of the rock. This information is used in a wide array of engineering applications such as foundation bearing capacity and rock anchors. Core Recovery (%)

What is a rockstrong coring system?

Halliburton designed the RockStrong coring system to withstand any application, including high-temperature/high-pressure environments and hard, abrasive rock formations without compromising performance. Halliburton's RockStrong coring system features a unique swivel assembly that is the most robust coring tool on the market.

What is a coring system?

Cores provide both geological and engineering information, and their analysis ultimately leads to a profitable field development. Many coring systems exist. The system used depends on the objectives for the coring program and on the physical constraints of both the formation and the drilling location.

Does Geo-ex do rock coring?

Geo-Ex performs rock coring services routinely. We core on landslides, dams and many other projects when rotary and auger tools are unable to penetrate. We have wireline (triple tube) coring systems for deeper projects, as well as conventional coring systems that attach to drill rods when confirmation cores are needed.
