MRE – Grosvenor Coal Mine – 29.11.2017 + comments 101 sealing

POINTS TO NOTE

CONSENT TO REMAIN IN OR ENTER THE  SEALING A PART OF THE MINE KNOWN AS LWIOI

[Pursuant to CMS&H Regulation 330]

{Regulation 330: Evacuating mine after sealing A person must not, without an inspector’s written consent, enter or remain in an underground mine after the mine, or part of it, has been sealed}

8 c/t SEAL ATMOSPHERE APPEARS TO HAVE TRENDED DIFFERENTLY THAN EXPECTED.

WERE WORKERS REMOVED FROM THE MINE BETWEEN 3PM ON THE 28^TH UNTIL SOME TIME AFTER 8:30 AM ON THE 29^TH?

I am satisfied that with the information supplied risk is at an acceptable level and give consent to complete sealing.

The Underground Mine Manager has shown that an acceptable level of risk has been achieved with respect to the sealing of the part of the mine stated above and consequently consent is given, pursuant to Regulation 330, for persons to remain in or to re-enter the underground mine.

An acceptable level of risk has been achieved by:-

1. Implementing a “Sealing Management Plan” that was developed using risk assessment and in consultation with a cross-section of mineworkers in similar manner to that required for the development of a Standard Operating Procedure.

NOTE: The Plan was acknowledged, pursuant to in a Mine Record Entry dated 21/08/2017 allowing the sealing to proceed.

2. Including in the “Sealing Management Plan”:

• Comprehensive sealed area monitoring that ensures adequate and accurate data on which competent decisions can be made and appropriate Trigger Action Response Plan and
• A comprehensive Sealing Management Plan checklist that is designed to verify that all aspects of the plan have in fact been progressively completed by those responsible,

3. Providing a copy of the Sealing Management Plan Checklist , signed off by the

Underground Mine Manager, verifying that everything has been done according to the Plan.
