RE:RE:RE:RE:stope backfill
RE:RE:RE:RE:stope backfillI am not aware of any publications regarding managing ground water from geological structures. This is a pretty specialised topic. It sounds like NCU was trying to use pressure grouting to slow the water inflow with the dyke. Pressure grouting techniques and effectiveness are highly dependent on the local problem and the contractor doing the work. I do know that pressure grouting is slow, expensive and frequently less effective than planned.
Unfortunately, NCU is being intentionally vague on the problem, so we can only speculate.
