UPDATE: Australian Landslide
The landslide occurred yesterday along near a coal mine that supplies the Yallourn
powerplant, one of the largest in the state of Victoria. Heavy rainfall this month has increased pressure on the mines wall. Engineers assessed the mine walls last week for seepage but reported no indications of eminent failure.
The adjacent Latrobe River has been entering the mine since the slide. Remediation will probably include rerouting the river to supply downstream dams and lakes which are now only receiving minimal flows from urban runoff.
The powerplant which usually supplies 22% of Victoria's electricity has been running at a reduced capacity of 30% since the failure. The mine produces around 18 million tonnes of high moisture brown coal to the powerplant annually using gps guided CAT D11s like this:
