• Risk Scope:
  Flood or inrush (water/mud) may occur into an operational pit. Includes natural occurring event e.g. extreme weather or the failure of dam (tailing or water storage - particularly above ground), major piping failure and connection to old workings.

• Control Objective:
  To ensure coal mine workers are not exposed to the uncontrolled energy/release of flood/inrush into operational pits.

Operational pits are designed in accordance with legislative, Australian Standard and BMA Engineering Design Standards: • GRM PLN Ground Control Management Plan • 100.01 GRM SOP Workplace Inspections and Access to Hazardous Areas

Regulated Structure Construction

• Structures must be designed and constructed in accordance with the respective Australian Standards and BMA Engineering Design Standards

• Select 3 water storage structures, and obtain relevant records to verify the following:

• Has each structure been designed and constructed in accordance with the respective Australian Standards and BMA Engineering Design Standards?

  Yes

  No

  N/A

Regulated Structure Monitoring & Inspections

• Registered Professional Engineer Queensland (RPEQ) integrity inspections must be conducted and records maintained (annually)
  
  Radar monitoring and surveying of high-risk geotechnical areas must be in place.

• Select 3 water storage structures, and obtain relevant records to verify the following:

• Has structure been inspected by a Registered Professional Engineer Queensland (RPEQ) and records maintained (annually)?

  Yes

  No

Regulated Structure [water] Level Management

• A system is in place to identify geotechnical hazards and monitor / manage water levels.

• Select 3 water storage structures, and verify the following:

• Is there a strategy in place to measure and monitor water levels?

  Yes

  No

  N/A

• Are OCE / Geotechnical Inspections in place, including appropriate management strategies?

  Yes

  No

  N/A

• Are actions being tracked and closed out?

  Yes

  No

Wet weather preparation audit (prior to wet season)

• (Consider having this added to 1SAP WM to ensure it's recorded/captured)
  • Wet Season Preparedness is completed and actions completed / close-out .

• Obtain wet weather preparation audit/s from previous and current year and verify the following:

• Have audit findings been recorded and actions raised / tracked to completion?

  Yes

  No

  N/A

• Review status against plan for current year, and interview 2 audit representative to determine progress. Is progress at an acceptable level?

  Yes

  No

  N/A

Mine Planning Design Processes

• Mine Planning Design processes for i.e. mud content above Draglines, any significant body of water above a pit.
  Geotech Checklist which accompanies every design.

• Select 2 unregulated storage structures (including 1 mud dam) and verify the following:

• Have the requirements in the geotechnical checklist have been implemented?

  Yes

  No
