Potential implication behind Oaky Creek incident - from water leakage to gas explosion

Note: The following is based on preliminary information and remains speculative. Please wait for official announcement.

• Water inflow at Oaky Creek may have caused roof strata failure, leading to possible longwall seal damage.

• Seal failure could have released trapped explosive gases (mainly methane) from the goaf into active areas.

• The incident has the possibility to escalate from a water control issue to a potential explosion risk underground.

• Methane-air mixtures in certain concentrations might create a highly explosive atmosphere.

• Production restart is likely to be delayed until gas risks are assessed and controlled.

• Recovery may require ventilation adjustments, resealing, and regulatory approval before safe re-entry.

• Overall, this could significantly extend Oaky Creek’s downtime.
