1. Introduction This internal compliance audit checklist has been developed to confirm that mining complies with the Department of Trade & Investment, Regional Infrastructure & Services (DTIRIS) approved Subsidence Management Plan (SMP) as per Condition 22 of the Tasman SMP Panel 7 approval dated 22/10/12 (Ref OUT 12/26174). The results of the audit are to be reported to the Inspector of Coal Mines and the Principal Subsidence Engineer within three months of completion of each panel.

2. Definitions Active Mining Zone (AMZ) report - A report completed by the Panel Team Leader (Deputy) and countersigned by the Area Leader (Shift Undermanager) detailing lifts taken, lift depths, hazards identified and comments on conditions and actions taken. Daily Plan - A plan prepared by the Production Manager outlining daily tasks and information relating to production including any changes to mining conditions and any variations to sequencing. Area Leader’s (Deputy’s) Lifting Plan – A plan prepared by the Mine Surveyor showing lifts to be taken, colour coded lift depths, stooks, remnant pillar sizes and sequence of extraction. Pillar Extraction Management Plan (PEMP) – Provides a framework for the protection of persons health and safety from pillar extraction activities at Tasman and to ensure compliance with relevant legislation and approval conditions. Pre Extraction Mining Review - A review conducted by the Technical Services team checking that approvals, plans and training are in place prior to extraction commencing. Risk Assessments - The overall process of risk analysis, evaluation and controls. Subsidence Control Zones (SCZ) – Areas designated for control of subsidence to protect sensitive surface features. Safety Interaction (SI) – Safety interactions generally involve a targeted discussion between employees to better understand the risks involved in an activity. The purpose of safety interactions is to reinforce safe behaviours and gain commitment to improve less safe behaviours. Tool Box Talk (TBT) – A TBT is a short safety talk delivered to the workforce on a specific subject matter. Trigger Action Response Plan (TARP) – A TARP is a system under which pre-determined actions are initiated in response to risk triggers. For example, an increase in roof bolting density may occur in response to the presence of a fault being encountered. Weekly Pillar Extraction Audits – A weekly audit of pillar extraction panels undertaken by the shift Area Leader, Technical staff and other members of the workforce. The audit aims to ensure compliance with the mine’s Work Health and Safety Management Systems and to identify and manage hazards in the production area.

4 NORTH EXTRACTION

Prior to extraction commencing in 4 North Panel, an audit of installed support and

geotechnical mapping was undertaken. As part of this audit geological features such as

cutters and faults have been marked with spray paint for easy identification.

In addition, the routine Geological Condition, Installed Support and Mine Hazard Plans

have been drawn up for 4 North Panel (see attached).

Please make yourself familiar with these plans. They are available in the crib room, on

the surface, in the Deputy’s Room and on the server.

HAZARDS – 1 WEST VS 4 NORTH

Lifting operations will be moving from a relatively deep area of the mine (up to 240m

depth of cover), to a relatively shallow area of the mine (<50m depth of cover).

As such the hazards around the face are likely to change. The deeper areas of Tasman

Mine often show quite good roof conditions, while rib conditions tends to be poor, being

affected by increased vertical stress.

Alternately, the shallower areas of Tasman Mine often show good rib conditions, but

poorer roof conditions, due to the lack of confining stress in the roof and the effects of

weathering in the roof strata.

It is therefore likely that during the early stages of extraction in Panel 4 North the roof will

be more prone to blocky failures in the lift. Coal webs and lifts can be left in order to

mitigate against this, at the discretion of deputies and miner drivers.
