Meeting Notes
NGC will source engineering sign off for rated concrete seal in 1:4 drift portal, with a view to work through risk management process to remove exclusion zone around 1:4 drift.
On 1/10/2018 NGC landed drone on top of H40 ventilation shaft openings with streamer attached and observed no noticeable direction of ventilation flow indicting shaft potentially static.
David Cliff asked if bag samples would be taken after hole through of bore holes GN2701, GN2702 and GN2703. NGC would assess opportunity if holes breathing out and risk assessment provides acceptable controls.
NGC are working with QMRS to developing a strategy for establishing gas monitoring in bore holes via risk assessment process.
NGC are working on establishing a concrete batching plant outside exclusion zones and developing a transport strategy for concrete.
