conquers the world

! Drilling conditions are difficult! Hole stability is a problem (broken

rock)! High capacity/productivity is

needed! Fuel consumption of DTH is an

issue


20/34

Applications and products

! Dimension stone industry! Construction! Aggregate quarries! Limestone quarries! Selective mining! Open pit mining

Product highlights


22/34

ROC D7C, D9C and F9C

Productivity, safer environment,less fuel

! Computerized drill plan, automaticrod change, computerizeddocumentation of drilling data

! Automatic engine control 30%less fuel

! Dry Cab 30% less hydraulichoses


23/34

Upgraded ROC L-series

! Higher productivity! Increased hole range! Better hole quality! Easier maintenance


24/34

ROC T15

! High productivity thanks to theuse of Atlas Copco reliablerockdrills

! Stable tramming makes itpossible to run the rig on rough

terrain! The radio-remote control takes

the rig safely to places whereyou usually dont dare to go

! Big coverage area makes it

suitable for many constructionapplications


25/34

CM 785

! Advanced, well proven feedsystem that optimizes theperformance of the rock drill

! Productive drilling in the mostchallenging rock conditions due tothe high torque and air available

! Proven and maintenance-friendlyhydraulic control system


26/34

ROC CARE service agreement

! Scheduled service! Inspection protocol! Extended warranty!

Satellite based monitoring system(ProCom)

Development Centra

! Major development fields at SDE Fluid mechanics Solid mechanics Mechanical systems Sound and vibrations

! The solutions should work as well in the desert as in a city in thenorth.


28/34

Tools

! Simulations: Ansys Solid mechanics simulations Adams - Adams is a motion simulation solution for analyzing the complex

behaviour of mechanical assemblies. CFD Open FOAM

PAM VA One SEA - Sound and vibrations Statistical energy analysis.

! Experiments on the actual rigs.! Rocktec


29/34

Fluid mechanics

!

Compressible flow in the drillingtube! Sometimes the flushing air is

mixed with a liquid in order tostabilise the walls.

!

In the hole: high velocity air-liquid-gravel mixture! Highly abrasive environment.

Flushing air

High Pressure

Suction

O(15) bar

Fluid mechanics

!

Hole diameters: 33 200 mm! Hole total depth: up to 55 m! Max feed velocity: 2 m/min! Particle sizes from

0.5 m to 5 mm! Requirement


32/34

Fluid mechanics

! Simulations of cooling (engine, compressor, hydraulics )! Simulations of flow/heat transfer in the engine room (the rig is

operated in the desert as well as in the north.)! Simulations of the abrasive blasting of the drill bit.! Sample kit: Accurate samples of the rock dust to indicate what

material being drilled.

We are committed to your superior productivity through

interaction and innovation.
