Sellicks Blast 02/07/2018 & 06/07/2018
We have two visible blasts coming up. The first will be on Monday (2nd July) and the location will be on top of the hill. You may have noticed the drill positioned on top of the hill over the last week. The forecast for Monday is for North-West winds, which will blow any dust cloud away from Sellicks Beach. The second Blast is planned for Friday (6th July) and will be located at the Southern end of the Quarry. The long range forecast for Friday at this stage is again for North-West winds.
With regards to the Blasts on top of the hill, we have over recent years stopped blasting in this area over the winter period. The reasoning behind this strategy was to minimise the visual impact with the hill ‘greening’ up over winter. When we blast in this area, the brown blasted material is in contrast to the hill, increasing the visual impact. This winter we are going to fire a few more blasts across the top, as with more moisture in the top surface with winter rains, the dust generated from the blast is reduced. The predominate wind direction over this period is also from the West, meaning any dust generated will blow away from Sellicks Beach residents. We hope the effort to minimise the dust impacts, outweighs the increased visual impact of this area. As the blasted rock is removed from each blast, we place soil at the front which can then be seeded. The cover of grass helps reduce the visual impact and also provides a cover of vegetation over the summer.
People may have also noticed some areas around the quarry starting to ‘green’ up as we move well into winter. To date we have spread around 3 tonnes of Rye Corn grass seed, with a further 5 tonnes planned. As we try to complete each season, disturbed areas are covered with top soil / sub soil. These areas are then hand seeded with Rye Corn. The Rye corn grass provides a good initial cover and when it dries out over summer maintains that cover, dropping seed for re-growth the following year. The recent area’s that have been prepared for seeding are across the top of the big hill and Western Screening mound. We still have more work to complete on the lower level of the Screening mound before we can seed. Additional to the grass seed, we are about to plant 2,500 trees across the site. We don’t have any new areas to plant trees this year, with these 2,500 trees replacing previously planted trees that have not survived and filling in gaps between existing trees. On average we plant around 2,000 trees per year.

Sellicks Blast 17/04/2018
Notification of a blast today that will be conducted on top of the hill and visible to the community. Weather conditions today are favourable with light winds forecasted, meaning the dust cloud should settle well within the pit.
Sellicks Blast 24/02/2018
The blast location will be in our Eastern Quarry development area at the top just behind the big hill, which is approximately 750m East of South Road. The wind forecast tomorrow is for a light North Westerly wind after lunch, meaning that any dust cloud will blow away from Sellicks, up and over the hills to the East.
For each blast conducted on site, we setup a monitor to record blast vibration and noise. The monitor station is located near South Road. All Quarries are required to adhere to Australian Standards limits for ground vibration and air blast overpressure (noise). Generally our readings are well below the limits and for some blasts not even registering at the monitor station.
Sellicks Blast 20/02/2018
We are planning to blast tomorrow afternoon at the Quarry.
We have been monitoring the weather and tomorrow does look ok to blast, based on the winds. BOM Forecast is “Winds east to southeasterly 25 to 35 km/h tending east to northeasterly 20 to 30 km/h in the morning then tending east to southeasterly 15 to 25 km/h in the evening”. I have also attached the Windfinder forecast FYI. Both indicate the wind will drop tomorrow and swing NE. We generally are ready to fire early afternoon, so we are expecting light to moderate NE winds at this time and the dust cloud produced should blow south of Sellicks Beach.
