Bulga Coal blasts between 9am and 5pm, Monday to Saturday, with the majority of blasts fired around lunchtime. Blasting is managed in accordance with the approved Blast Management Plan and complies with the conditions outlined in the Environmental Protection Licence 563 and in our development consent.
Before mining can begin, topsoil is removed and stockpiled so that it can be reused during the rehabilitation process. Once the topsoil has been removed, it is necessary to blast the underlying rock so it is broken into a manageable size which can be handled by either the dragline or excavators.
Blast management aims to minimise the impact to the community through blasting activities. Noise, overpressure, vibration and dust exposure from blasting activities must comply with limits that are set by regulatory authorities for neighbouring residential properties.
Monitoring is undertaken to record:
- Measured air blast overpressure;
- Measured ground vibration; and
Results from the blast monitoring are reported quarterly on the website in the Environmental Monitoring Report and also reported in the Annual Review.
