Coal Inspectorate | Alert | No.396 V 1 | 21 September 2021

Fatality resulting from a fall of ground at an underground coal mine

What happened?

At approximately 11:00 pm on 14 September 2021 three coal mine workers were conducting work in a conveyor drift at Crinum underground coal mine when a significant fall of ground from the roof area of the drift occurred. This resulted in one worker being fatally injured and a second worker being seriously injured.

How did it happen?

Initial indications are that two coal mine workers were drilling Rocsil application holes into the roof of the drift using a QDS Bolter. Whilst drilling the application holes, a large quantity of roof material has dislodged from the roof and fallen onto two of the workers. A third coal mine worker, who was working in the adjacent area, initiated the emergency response.

Key issues

The incident is under investigation. The underground part of the coal mine has been evacuated and secured to prevent unauthorised persons entering the mine until it can be determined that it is safe to do so.


The recommendations contained in this alert are general in nature, relating to the management of strata hazards in underground coal mines, and are not direct findings relating to the cause of the accident at the Crinum mine.

The Mine Operator should ensure that the Site Senior Executive and Underground Mine Manager at their underground coal mines review their Principal Hazard Management Plan for Strata Control to ensure this is effective to prevent any potential for a similar incident. Consideration should be given to the following:

Investigations are ongoing and further information may be published as it becomes available. The information in this publication is what is known at the time of writing.
