HW 300 Highwall Miner
• In the current market cost reduction is imperative to be competitive.
• Is your operation moving towards an uneconomic strip ratio ?
• Is development of an Underground Operation on the horizon ?
• The HW300 can offer a low cost production alternative that can extend your
open cut operation.
• The HW300 can access additional Coal once thought of as unattainable and
as such provide additional revenue.
• Without the need for employees to go underground.

What is Highwall Mining?
• The ability to mine coal from…
– a visible, horizontal coal seam
– rectangular, parallel, unsupported drives
– unmanned cutter head and coal transport system
– mining unit positioned outside the drive, in front of the highwall
No people underground!

Why use a Highwall miner?
Maximum Extraction – Low cost coal compared to traditional mining methods
Safe Operation – The entire mining cycle is completed by a four man crew,
with no personnel going underground at any time.
Low cost production method:
– No removal of overburden required
– No lighting, ventilation, roof support, etc.
– Highly automated, high production per man hour
Extracts additional coal, otherwise lost:
– Mines coal beyond economic strip ratio
– Under spoil heaps
– Under some surface features (environmental, infrastructure, cultural)
Excellent Mobility – Highwall miner trams easily from entry to entry and
discharges coal in tight spaces
Result: More coal from the same property, using existing infrastructure
– Higher return on investment
– Less environmental impact compared to full Open Cast mining
– Possibility to “direct-ship” coal by selective mining

Introduction to WDS
• Mining & Energy Sector services company
• Underground mine services cover all facets of the business
• Seeking to diversify into the Open Cut (O/C) sector
– HWM deemed a good addition to the suite of services provided
– Bridges the gap - current U/G and future O/C services
8 / Longwall Mining Conference 2014
Typical Highwall Mining Applications
• Final highwall of an Open Pit
Australian Target Market
• Trench mining
Opportunities exist in Australia
• Contour mining
Not Common in Australia
