Dewatering Infrastructure Upgrade Project Supervisor Anthony Symonds with the new pumping system
One of those engineers is Site Services Manager Stewart Cluning.
‘I’m very excited to see new generation of pump infrastructure commissioned,’ he said.
According to Loy Yang’s Head of Mining, Jeff Hobson, the project is the culmination of work by half a dozen dedicated civil, mechanical, and electrical engineers, who shared a vision to build a dewatering and fire service solution for the second half of the mine’s life.
‘The pump sets used on this project are capable of pumping anything the mine can throw at them,’ he said.
‘Similarly, some of the most advanced SCADA1 technology has been utilised to monitor and control the system automatically.’
‘The solution developed will improve the mine’s fire-fighting capability by utilising the new high-volume pump station to move more water when its required and remove rainwater from the mine during peak one in 100-year storm events.’
General Manager Coal Operations Steve Rieniets said the $40 million investment by AGL is testament to the designs and innovative solutions of Fire Service Engineer Rohan Bett.
‘One of Rohan’s mantras was to “begin with the end in mind”,’ he said.
‘He delivered on this brief with that mantra. The portable floating pump stations will move with the growth of the mine, whilst the pipelines are sized and located to remain where they are until 2048.
‘If you can’t manage water in a mine the size of Loy Yang you are in a lot of trouble. To that end this is a very elegant engineering solution.’
- $40 million investment in de-watering system and control technology
- Approximately 60 employees and contractors worked on construction for 19 months
- 3kms of de-watering and 3.5kms of fire service pipelines were installed
- Nine pumps installed with scope for additional pumps
- Two pumps installed on floating pontoons at the base of the mine
