FUNDAMENTALS IN MODERN COST EFFECTIVE MINING

AGENDA

Driving forces in modern cost effective mining

– Quality in mining methods

– Productivity

– Automation

– Infrastructure

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

QUALITY IN MINE DEVELOPMENT ROCK MECHANICS

6m6m x

6m

13m

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

System Overview

Safe remote line-of-sight

operation in unsafe areas

Bluetooth communication link,

for a safe and reliable remote

link

No infrastructure required

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

INFRASTRUCTURE

INFRASTRUCTURE CHALLENGES

HISTORY TODAY

Do we have an education infrastructure supporting world class Mongolian mining ?

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.
