Coring Tool

Coring Tool

 

a device for taking rock samples from the face or walls of a drill hole. Rotary, hammer, or forced face coring tools are used for investigating the physicomechanical properties of the foundation bedrock of engineering structures (the last type is used in soft rock and is driven in by pressure). When drilling exploratory holes for hard minerals, lateral coring tools (with which samples are scraped or drilled from the walls of the hole) or explosive tools are used. The use of the lateral coring tools permits the partial replacement of core drilling by more efficient solid drilling.

In addition, Halliburton s new HRSCT-B hostile rotary sidewall coring tool was deployed on both rigs, taking samples at three times the volume of conventional core samples and allowing for more meaningful lab results given that the larger samples offer a better representation of the formation.
Furthermore, our new core barrel system is designed for both standard and pump-in applications, so there is no longer a need to keep different coring tools systems on the shelf, reducing net working capital requirements for owners." www.mining.sandvik.com
Under the agreement Sandvik Mining and Construction will distribute Hagby-Asahi's exploration drill rigs and coring tools in Latin America, Africa and Australia, as well as in Russia and the former Soviet republics.
However, they note that some of the contract drilling divisions 'are battling to secure enough work at acceptable prices.' Nevertheless, coring tools sales volume is recovering from the bottom of the downturn and BL's new products are rapidly gaining acceptance.
