Wyodak Coal Mine - Background

Located in the Gillette Energy Complex.

Mine mouth power station generating 800 net MW.

Production reached approximately 5.7MT in

2011.

Overburden is removed by conventional truck / shovel operations, with average stripping ratios of 2.6:1.

Multi seam operation with variable coal quality.

Blending is required to meet end user requirements, blending occurs at CPP.

Wyodak Coal Mine - System

Two (2) Stamler feeder breakers:

One (1) track mounted; and

One (1) skid mounted

2,150TPH overland conveyor powered by twin

500HP VD DC motors

2,150TPH feeder conveyor

High angle conveyor (HAC) inclined at 60 degrees for a 50m lift, powered by 300HP DC motor.

Two 4,500T coal silos located at CPP.

Wyodak Coal Mine - Results

Efficient, environmentally friendly, low cost solution.

Computerized communication, command

and control system enables

single operator control.

Feeder breakers;

OLC; and

Grasshopper conveyors.

System has delivered 93% overall availability and has been in operation since 1994.

Wyodak has seen a reduction in carbon footprint.

Wyodak has seen a reduction in operating cost per tonne.

Other IPCC experiences

An number of other mines in the powder river basin have

taken Wyodaks lead.

To the right can be seen a IPPC system provide to

Banpu for Mae Moh mine in

Thailand in the 90s.

Existing Types of Haulage from Mine to Processing Plant

Batch Haulage

Utilizes trucks

Provides greatest autonomy/flexibility

Highest cost of ownership, lower tonnes per hour

Labor intensive

Semi Mobile Haulage

Combination truck and IPCC

Additional mine planning required

Productivity gains, lowers cost of ownership

Continuous Haulage

Maximizes systems, minimizes individual equipment

Greatest tonnes/hour potential, lowest cost of

ownership

Least labor intensive

Joy Global IPCC 3D Modeling Capabilities

Concept to Reality

Ability to optimize production consistently

Validate

Update

Total Cost of Ownership (TCO)

Detail evaluation on a side-by-side TCO sensitivity or what if analysis, which allows one to quickly understand the quantified

reasoning with respect to a comparative analysis and the resulting

optimal equipment selection

Capital acquisition that disregards equipment reliability and performance can pose a significant overall financial risk regarding

the viability of a given mining application

Total Cost of Ownership analysis is advantageous over using just capital justification because product price is one of the most un-

predictable cash flow components

Conventional Net Present Value (NPV) based analysis requires a full system or complete mine-site study in order to understand the revenue

associated with a particular mining application.

Target key factors in Total Cost of Ownership

Reliability and Productivity have the greatest impact on TCO ($/ton)

Reliability= Availability + Component Life + Support

(Maintenance) (Design Quality) (PT P&H MinePro)

Joy Global Partners on Total Cost of Ownership (TCO) Analysis

Partner in development of detailed TCO sensitivity or what if analysis, which allows quick understanding of the quantified reasoning with

respect to a comparative analysis and the resulting optimal equipment

selection

Work together to analyze capital acquisition with equipment reliability and performance to analyze overall financial risk regarding the viability

of an IPCC System application

Joy Global IPCC System The TCO Advantage:

EASE OF MAINTENANCE

PreVail Remote Health Monitoring for data analysis and diagnostics

Maintenance is performed as a complete integrated system and not as individual components operating in series

PRODUCTIVITY

System components linked for continuous optimized production

SUPPORT

One stop after market Joy Global Smart Services support for entire System

SAFETY

Remote operation technology for complete system

Fewer operators and support equipment
