SANDVIK DB311―SECONDARY BREAKING DRILL RIGS

Sandvik DB311 is a Secondary Breaking Unit (SBU) for rock boulders reduction and ore facilitation in mass mining methods, enabling fast recovery of full mining production when large rock boulders cause draw points blockages. Sandvik DB311 is a fully autonomous unit based on self-contained diesel hydraulic carrier, with on-board water tank and large air compressor for air-mist flushing. The drill rig does not require any connection to external power nor water hose, thus allowing fast set up and removal in production areas.

The robust telescopic boom with double rotation actuators and compact feed offers an easy positioning within confined spaces at drawpoints. The high frequency rock drill enables fast drilling, short time exposure in drawpoints. Drill and blast method is used to fragment the boulders. The explosive charging system is not included.

The drill rig layout is designed for good visibility and stability. This, and the powerful four-wheel-drive articulated carrier, ensure fast and safe manoeuvring in narrow drifts. The operator environment and added automatic functions allow the operator to concentrate on safe, fast and accurate drilling. All the service points are well protected but still easy to access.
