Sandvik Introduces New Multi-Functional Core Barrel System for Drilling

Equipment and service provider Sandvik Mining has unveiled a new multi-functional surface and underground (NSU) core barrel system for core drilling.

The newly developed system has interchangeable components including standard and pump-in applications, capable of increasing productivity for miners. The innovative design offers cost-efficient solutions by reducing networking capital and spare parts inventory, ensuring safer operations.

“The newly patented iQ-FCV valve provides and maintains a constant alert through sustained high water pressure, assuring the operator that the inner tube assembly has positively latched into the core barrel. “This eliminates mislatches and ensures that valuable time is not lost,” says Sandvik mining core drilling product line manager Chris Daws.

“For better water efficiency, the iQ Valve has been designed to always retain the volume of water in the drill string even in broken ground or dry holes, which is an important benefit in core drilling,” he adds.

The NSU system features automatic latch-locking and latches for safety and a knuckle joint for ease of handling. The core drilling unit doesn’t require cable eyes or cable splicing, making it easier for maintenance operators to repair on site.

“The Sandvik NSU and forthcoming H surface and underground (HSU) core barrel systems share the majority of components used in the core barrel head assembly,” says Daws.

“With the interchangeable design for both systems, the NSU core barrel head assembly can be converted into an HSU core barrel head assembly, and vice versa. This will significantly reduce parts and spare parts inventory.

“The new core barrel system is designed for both standard and pump-in applications, which means there is no longer a need to keep different coring tool systems on the shelf. It also reduces the net working capital for the owner,” he adds.

Sandvik plans to launch the HSU system later this year.
