DB331SECONDARY BREAKING DRILL

1. SANDVIK DB331 - SECONDARY BREAKING DRILL

Sandvik DB331 is a Secondary Breaking Unit (SBU) for

rock boulders reduction and ore facilitation under draw

points, it is an autonomous drill based on self-contained

diesel hydraulic carrier, with on-board water tank and large

air compressor for air-mist flushing.

The robust telescopic boom offer a medium reach up to

8 m height, the double rotation actuators and compact

feed offer easy positioning inside the draw point, and the

high frequency rock drill enables fast drilling, short time

exposure in confined space.

Drill and blast method is used to fragment the boulders.

The explosive charging device is mounted on the charging

head, and the explosive initiator and cartridges are

provided by the explosive supplier.

The operator controls the drilling and tramming functions

of DB331 remotely and safely with an ergonomic RRC

panel and a remote video assistance. 

The video system includes a remote monitor on tripod,

a 3D-zoom camera and multiple wide angle cameras to

enable the unit tele-operation from a safer location.

The drill rig is designed for good visibility and stability, the

powerful four-wheel-drive articulated carrier ensures fast

and safe maneuvering in compact underground drifts.

All the service points are well protected but still easy to

access.

Altogether Sandvik DB331 offers a safe operating process

for effective ore facilitation tasks, the unit releases

blockages in draw points thus enables a high production

rate in large scale mining.
