Subsidence Management Plan - Quetools

Fauna and Fauna HabitatNo significant impacts are predicted for fauna and their habitats as a result ofsubsidence (see Section 7.3.1 of the SMP Application – Written Report) and nospecific monitoring has been recommended.6.4 PUBLIC UTILITIESForest RoadA specific management plan has been developed for Forest Road (Annex C)which identifies specific monitoring programs for subsidence impacts. Preminingmonitoring will comprise documented visual inspections of the roadto record any existing damage/issues. Monitoring during mining willcomprise documented daily visual inspections of the potentially affectedsection of Forest Road when the longwall face is approaching within 50m, andcontinuing until the face is 200m past, and at the completion of mining toestablish that no further subsidence impacts are likely. The Forest RoadSubsidence Management Plan was developed in consultation with SingletonShire Council and the Department of Lands.Electricity Transmission LinesA specific management plan has been developed for the electricitytransmission line within the Application Area (Annex B) which identifies thespecific monitoring programs for subsidence impacts. The monitoring ofsubsidence impacts will comprise three phases and will be undertaken priorto mining to record pre-mining status, including condition and tilt of thepoles, during mining to identify any subsidence impacts and implementmanagement measures, and at the completion of mining to establish that nofurther subsidence impacts are likely. The Electricity Transmission LineSubsidence Management Plan was developed based on previous experienceundermining transmission lines on GCCM’s lease and consultation withEnergyAustralia.Telecommunication LinesA specific management plan has been developed for the Telstra assets withinthe Application Area (Annex A) which includes a subsidence monitoringprogram. Prior to mining, line testing on the spare pairs in the 10 and 6 paircable across the Application Area will establish the baseline condition of thecable, with the test being repeated at the completion of each longwall panel.If significant surface subsidence is observed during routine monitoring,physical inspection of the network will be undertaken.
