3.6 Ventilation System
3.6.1 Ventilation requirements
Total mine ventilation requirements will change with the number of panels and their extent, including
standing gate roads. A nominal assessment of ventilation requirements is shown in the table below. These
quantities are indicative and will depend on seam gas management requirements, standards of mains
stoppings and configuration of the rear block shaft (intake or exhaust)
Item Quantity (m3/sec)
Longwall 2 heading 75
Development Panels (last c/t) 55
Mains panel (cumulative of flanks) 70
Standing gateroad 40
Total Panels 350
Conveyor Drift and belt road air dump 80
Fuel bay 15
Transformer and pumps 15
Misc 10
Total Ancillary 120
Total Ventilation requirement 540
Table 8 Ventilation Quantities
3.6.2 Airways
The initial development of the mine will be ventilated by the men and materials drift on intake, the conveyor
drift on intake, an upcast (return) shaft of 5.5 metres diameter and a free venting intake shaft.
3.6.3 Surface Fans
The upcast shaft will be fitted with three identical centrifugal fans with VVVF speed control. The specification
calling for 2 fans to deliver 400m3/sec with the third spare on the initial shaft. The fan static pressure at this
operating point will be approximately 4 kPa. Three fans operating in parallel may be required for LoM
ventilation requirements.
3.6.4 Ventilation and gas monitoring
The ventilation system will be monitored as follows
1. 30 point infrared tube bundle system reticulated throughout the mine to monitor the active location
of the explosive fringe in the active goaf, status of the goaf stream, status of sealed goafs and
chosen roadway analysis in conjunction with real time monitors.

2. Real time monitoring as required by regulations, monitoring for oxygen, carbon monoxide, carbon
dioxide and methane.
3. Safegas / Seagas system or similar to collect data, provide trends and alarms and predetermined
TARPS.
4. Gas chromatograph to analyse discrete samples from active and sealed areas
5. Surface barometric pressure transducers
6. Air velocity transducers
7. Surface fan pressure transducers
8. Pressure differential transducers at select locations between intake and return
9. Green House Gas monitoring system
3.6.5 Heat management
The general approach for heat management is as follows
1. Maintain relatively high velocities on longwall and development faces to minimize effective
temperatures. In development areas 760mm duct will be used instead of 600mm duct.
2. As far as practicable, ventilate large equipment to return airways e.g. bleed over gate road drive
heads through coffin seals and main pumps through stoppings to return airways
3. Segregation of drift, mains trunk and gateroad belts and use of belt road air dumps
4. Provide for bulk cooling of intake air
4. Integrated Operational Risk Management
4.1 Group Technical Standard 02 Integrated Risk Management Standard
As defined in GTS02 the Integrated Risk Management Process flow diagram, depicted below shall be the basis for risk management throughout Anglo American.

A key output from integrated risk management shall be a single, integrated Risk and Critical Control
Register for each Business Unit, operation and project. These registers shall be structured such that the
Business Units can analyse and consolidate the data from across its operations/projects allowing the
material risks to the Business Unit to be reflected and managed from a single integrated Business Unit
Risk and Critical Control Register.
These registers shall be structured such that the data required for reporting purposes can be readily
filtered from the respective registers.
4.2 Operational Risk Assessment Methodology
It is crucial that all Coal Mine Workers at Grosvenor Mine operations knows what is expected in terms of
managing safety in their workplace. Anglo has invested heavily in the development a simple, uniform
approach to Safety Risk Management so that all personnel have the training, tools and resources
required to help them make the right decisions in their workplaces.
In using this approach, Anglo has adopted a cohesive Four-Layer Approach recognising that safety risk is
affected by decisions made for different reasons, at different layers within the organisation and should be
controlled at each of these decision points. Decisions made at the top can have a huge impact on
underlying layers. Within each layer, application of risk assessment methods and tools will vary
depending on the nature of the assessment, the detail required and a number of other factors. It is likely
that several tools would be used in each layer.
Figure 5 illustrates this Four Layered Approach with a more detailed Step by Step Guide on applying this
approach included in Table 3.

OVERALL FUNCTION, SITE MAJOR HAZARD, BASELINE OR FULL SITE RISK ASSESSMENT.
Objective: to look across an entire site, find potential major incidents and analyse, establish controls, document, and apply approaches so related risks are as low as reasonably practicable (ALARP). This layer also applies to executive decisions made in head offices and in specialist functions.
PROJECT, CHANGE OR ISSUE-BASEDRISK ASSESSMENT.
Objective: to review equipment, changes, and major incidents for risks so related risks are tolerable.
ROUTINE AND NON-ROUTINE TASK BASEDRISK ASSESSMENT.
Objective: to develop effective safe work expectations - guidelines, standard operating practices (SOPs), job plans, etc. - and review tasks where adequate SOPs are not available so related risks are ALARP.
‘EVERYDAY’, CONTINUOUS, FACE LEVEL RISK ASSESSMENT.
Objective: to have the person ‘stop and think’ and proceed with a task only if safe.
Figure 5 The Four Layered Approach to Risk Management
The growing global reach of Anglo’s operations, combined with widely varying underlying safety cultures
and maturity, has resulted in a range of risk management processes that vary in quality and application.
Anglo’s Peer Review process and fatality investigations have highlighted the importance of creating a
standard Anglo approach to managing risk assessments and methods of risk control. In this same way, it
has been recognised that these same leading edge practices and resources are equally as applicable to
the effective control of all hazards and risks across an operation, not just safety risks. Operational
Performance, Regulatory Impacts, Occupational Health, Environmental Management and Community
Expectations [to name a few] are all potential sources of harm to our businesses and must all be subject
to the same rigour of risk management analysis and effective control.
As such, Anglo has developed a Group Technical Standard GTS 02 Operational Risk Management
[and a range of supporting guidelines and templates] to provide a standardised risk management
approach across its operations.
This standard forms the basis of the Integrated Operation Risk Management Processes in place at
Grosvenor Mine.

vii. Define the existing Preventative and Mitigation/Recovery controls in place
viii. Conduct a Control Effectiveness analysis of the existing controls [the Control Profile]
ix. Review the Hazard Profile against the Control Profile and determine if the risks are at Acceptable
Levels and As Low As Reasonably Practical [ALARP]
x. If risks are not ALARP, define new controls and conduct new effectiveness analysis until risks are
tolerable
xi. Determine an Action Plan for establishing new required controls
xii. Define the Critical Controls and assign ownership, accountabilities and the monitoring and auditing
requirements for each
xiii. Transfer the critical controls into the Critical Control Monitoring system to ensure they remain
available, reliable and survivable throughout the life-cycle of the hazard
xiv. Document the information from the analyses in a Risk & Critical Control Register
xv. Ensuring the Risk & Critical Control Register it is kept up to date including integration of results
from the Critical Control Monitoring system as well as any risk assessment analysis done at any of
the Four Layer risk assessments
The outcomes of this Step-by-Step process are summarised in the following sections with full details
incorporated into the site Safety and Health Management System.

4.4.4 Principle Hazards
As developed during the Operational Baseline Risk Analysis Process and defined in the Hazard Inventory,
those hazards with the potential to cause Multiple Fatalities are -
1. Fire (Surface and UG)
2. Explosion
3. Strata Failure
4. Spontaneous Combustion
5. Outburst
6. Inrush / Inundation
7. Vehicle Interactions
8. Ventilation
9. Gas Drainage
10. Gas Monitoring [Management]
11. Emergency Preparedness & Response
12. Toxic/Irrespirable atmosphere
Each of these Principle Hazards have been subject to either a detailed Bow-Tie Analysis and/or HAZOP
analysis. The functional process of the Bow-Tie Analysis is to develop-
i. Fault Tree Analysis of Causation and identification of Preventative Controls
ii. Event Tree Analysis of Consequences and identification of Mitigation / Recovery Controls
iii. Control Analysis of each group of controls to determine Control Profile [Effectiveness]
iv. Risk Analysis of each Causation and Consequence element to determine Risk Profile
[Ranking]
v. Comparison of Risk Profile vs. Control Profile to determine Acceptability of Risk
vi. Identification of New and/or Improved Controls where risk levels as regarded as unacceptable
vii. Identification of Critical Controls, assigning Owners to each critical control and defining
Monitoring Requirements and Risk Indicators for each
viii. Identification of any Specific Actions required to execute any of the control strategies, together
with action owner and completion date, finally
ix. Defining the Assurance, Status Tracking and/or Governance systems to ensure all controls
are in place and remain effective
The outcomes of these Bow-Tie analyses are contained in detail in the site portfolio of Bow-Tie Analysis
[as drawn using Bow-Tie XP] and the GTS02 compliant Baseline WRAC and Risk and Critical Control
Registers.

i. Break the designed control system into Nodes for detailed analysis
ii. Define the required Performance Criteria for each node
iii. Identify potential Deviations from these normal operations
iv. Identify how each deviation may occur, its potential consequence and whether it presents
an Operational or Hazardous risk
v. Identification of Preventative and Mitigation/Recovery Controls for each plausible
deviation
vi. Control Analysis of each group of controls to determine Control Profile [Effectiveness]
vii. Comparison of Risk Profile vs. Control Profile to determine Acceptability of Risk
viii. Identification of New and/or Improved Controls where risk levels as regarded as
unacceptable
ix. Identification of Critical Controls, assigning Owners to each critical control and defining
Monitoring Requirements and Risk Indicators for each
x. Identification of any Specific Actions required to execute any of the control strategies,
together with action owner and completion date, finally
xi. Defining the Assurance, Status Tracking and/or Governance systems to ensure all
controls are in place and remain effective
Essentially, the HAZOP examination procedure systematically questions every part of a process Or
operation to discover qualitatively how deviations from normal operation can occur and whether further
protective measures, altered operating procedures or design changes are required. The examination
procedure uses a full description of the process which will, almost invariably, include a Process &
Instrumentation Diagram [P&ID] or equivalent, and systematically questions every part of it to discover
how deviations from the intention of the design can occur and determine whether these deviations can
give rise to hazards. The questioning is sequentially focused around a number of guide words which are
derived from method study techniques. The guide words ensure that the questions posed to test the
integrity of each part of the design will explore every conceivable way in which operation could deviate
from the design intention. Some of the causes may be so unlikely that the derived consequences will be
rejected as not being meaningful. Some of the consequences may be trivial and need be considered no
further. However, there may be some deviations with causes that are conceivable and consequences that
are potentially serious. The potential problems are then noted for remedial action.
The main advantage of this technique is its systematic thoroughness in failure case identification. The
method may be used at the design stage, when plant alterations or extensions are to be made, or applied
to an existing facility.

4.5 System Integrity
To provide a level of governance and assurance over the critical controls identified by the Integrated
Operational Risk Management process, three elements together comprising the Critical Controls
Management System have been developed. These being-
1. All Critical Controls are developed in compliance with the GTS 02 Integrated Risk
Management Standard, detailed in the site Risk and Critical Control Register and
recorded in the site Enablon risk management module and/or the Ellipse System
2. All Critical Control Assurance Actions required to validate that the critical controls have
been implemented and remain effective are defined, issued, recorded and reported
against using the site Enablon risk management module and/or the Ellipse System
3. A set of System Integrity Controls developed to ensure that the Critical Control
Management System itself remains effective are also defined, issued, recorded and
reported against using the site Enablon risk management module and/or the Ellipse
System
Compliance with the requirements of the Critical Control Monitoring System is key to ensuring the
ongoing effective control of the hazards and risks across Grosvenor Mine. These system integrity controls
are captured in the underpinning HAZOP for the Management Overview Plan.
Further to this, a suite of “Quality Control Assurance” Critical Controls were also identified for an
additional level of onsite governance. These Critical Controls were identified by the General Managers
and Underground Mine Managers from across the UG operations in response to the Grasstree Mine loss
of life incidents. These Critical Controls were based on recent incident history and were determined as
fundamental risks that required an additional level of assurance built into their auditing process. The
Quality Control Assurance Critical Controls scrutinise the audits completed in areas where high probability
Critical Control failures have been identified. The addition of these assurance processes validates that
quality Critical Control audits are taking place and that the effectiveness scores given to the Critical
Controls are truly representative.
A summary of the System Integrity Controls are listed below:

Basic Principal Hazard Management System
Introduction and basic explanation of Integrated Operational Risk Management process, the Safety and Health Management System, the SHMS Mine Overview Plan, all Principal Hazard Management Plans and the Critical Controls Management System
Induction & Refresher
11. Corrective Action
Corrective Actions/Defects will be reported using the Hazard, Defect and Incident Management System
and will be recorded and managed in Enablon.
12. Audit and Management Review
The SSE shall ensure that the Critical Control audits detailed in the Critical Control Management system
integrated with Enablon, including the System Integrity controls, are completed at the designated times.
The Plan shall be subject to a program of auditing to determine whether the mine activities conform to the
Plan, and whether the arrangements in the Plan are adequate, implemented and effective. This program
shall include:
• Internal critical control auditing on a yearly basis, and
• External auditing every 3 years (e.g. OMS, OCA and GTS auditing).
• The audit findings shall be acted upon through the corrective action process and review
mechanisms.
• Internal and external audits of the Plan will be identified in the mine Audit Schedule.
In undertaking any review the Document Owner must be cognitive that the PHMS is an integrated
system. Subsequent revisions to this document or system should only be done with a defined
understanding of the basis and structure of the entire “as developed” system.

15. Appendix I Control Effectiveness Matrix
Control Type 6 Elimination: the complete elimination of the hazard by design
5 Substitution / Minimise: replacing the hazard, material or
process with a less hazardous one, or significantly the magnitude
of the hazard or material so consequences are greatly reduced
4 Engineering: incorporate controls into the design or redesign
the equipment or work process
3 Separation: placing a physical barrier on the hazard by
guarding or enclosing it
2 Administrative / Procedural: providing control such as
training and procedures
1 Personal Protective Equipment: use of appropriate and
properly fitted PPE where other controls are not practical

Control Quality
• Reliability: will the control operate on demand as intended
• Survivability: will the control remain unimpaired during the unwanted event
• Availability: will the control be available to perform its function
The Control Effectiveness method provides four percentage categories that express an overall opinion of reliability, survivability and availability. A- 90% or more of the time the control will operate, survive and
function as required B- 60 to 90% of the time the control will operate, survive and
function as required C- 30 to 60% the control will operate, survive and function as
required D- Less than 30% of the time the control will operate, survive
and function as required
Control Effectiveness A GREEN control rating indicates that the control should be effective. This is the desired effectiveness of every control but the matrix indicates that even a 90% quality Administrative or PPE control is not considered to be an effective control. The intent of this design is to promote the development and application of harder controls such as Engineering or Substitution A YELLOW control rating indicates a satisfactory control that could be improved to a green either through improving its Quality or by changing its Type. Yellow controls should be improved first if total control effectiveness for an unwanted event is inadequate RED control rating indicates that the control does not contribute effectively to reducing the risk of an unwanted event. The CER method provides a rating for each control. Overall Event Control Effectiveness is a summary of the total effectiveness of all controls. To establish this overall status the set of controls and their CER ratings should be examined. The decision that the set is adequate can be tested by the rule :- There should be two GREEN preventative controls for every cause of a priority unwanted event
