This document discusses key topics in modern cost-effective mining, including improved quality in mining methods, increased productivity through automation and remote control, and the infrastructure needed to support new technologies. It provides examples of how drill rig control systems and quality rock mechanics like shotcreting can improve mine development quality and productivity. Automation through technologies like radio remote control, tele-remote control of multiple machines, and fully autonomous machines is described as having the potential to improve productivity by 40-80% by allowing work through shifts and blasting. Challenges like operating heavy equipment remotely over long distances and a lack of educational infrastructure to support new technologies are also addressed.

FUNDAMENTALS IN MODERN COST EFFECTIVE MINING

3. 3
AGENDA
 Driving forces in modern cost effective mining
– Quality in mining methods
– Productivity
– Automation
– Infrastructure

4. 4
Improved control and quality of drill and blast.
Direct hydraulic control HISTORY
– Operator use their own drill pattern
– Low control of drill holes
– Explosives adjusted to poor drilling (fully charged)
– Result: Poor advance rate. Damage surr. Rock
– More over-breake
Rig Control System TODAY
– Standardized drill patterns
– Good hole control
– Smooth blasting of contour holes
– Result: Good advance rate and minimized
damage of surrounding rock

 Typical over break in many mines = 20% . Drive size increases to 6m*6m from 5m*5m
 Pillar width reduced from 16 to 14m. Due to fracture zones (bad drilling/blasting) solid pillar is reduced further
 Effective pillar width now approx. 13m = 18.7% less than design
 Smaller pillars mean increased rock stresses on remaining pillar
 Increased risk of rock bursts, squeezing of blast holes, brow failures, floor heave, etc etc
Planned driftsize 5m*5m
Planned pillar size 16m

7. QUALITY IN ROCK MECHANICS
 Shotcreting
 Meshing
 Bolting
 Cable-bolting
 Data logging for QC

System Overview
 Safe remote line-of-sight
operation in unsafe areas
 Bluetooth communication link,
for a safe and reliable remote
link
 No infrastructure required

14.  The second generation, fixed tele-remote
control installation is at LKAB Malmberget
mine in Sweden.
 One operator can monitor and control up to six
Simba drills. (3 operators are used)
 Can work through night shift when no
personnel is allowed in the mine
 System delivered and installed in 2012
 W-LAN

15. TELE REMOTE AUTOMATION
Challenges
 14 ton loader operating in a 10 ton loader sized drift
 Control room located in city 80 km from the mine.
 Operators with no underground experience.

16. INFRASTRUCTURE

17. INFRASTRUCTURE CHALLENGES
HISTORY TODAY
Do we have an education infrastructure
supporting world class Mongolian mining ?

18. INFRASTRUCTURE CHALLENGES
Technology development needs to be supported by the Government with a strategy to
achieve the following:
 Technical secondary schools to have up-to-date programs on new technologies.
 Universities to have competencies for teaching new technology in addition to basic
mining theory. In the long term to offer assistance in R&D projects for the industry.
