A Bali-based mining company has blast-ruined the Bali Mining Corporation’s flagship mine site, a day after it went on a rampage that injured five miners and injured at least four other workers.
According to a report by local media, the mine’s blast valve, which normally releases helium-3 gas, suddenly burst on Monday, causing the explosion.
Three workers were injured, while three others were seriously injured.
The company has since been placed under investigation by the BCA, which is probing the incident.
It was the second time in two months that a mine in Bali’s central Sulawesi province had blown up.
In May, an explosion ripped through a mine site in Baniyan, killing four people.
A spokesman for the BCO told Al Jazeera that the company is conducting an inquiry and will not comment further.
However, the company has not yet confirmed the cause of the blast, and there have been no reports of any injuries.
The Bali mining project was built by the Sulaweera-based Sulaweb Industries.
It has been a long-standing source of conflict between Bali and neighbouring Indonesia, where the Bornean island has a large mining industry.
In March, the B&C’s Sulawedeera-listed mine was forced to suspend operations because of high levels of mercury in its water supply.
In April, an accident at the site left three workers dead, and the company said it had begun cleaning up.
The mining company’s operations were also disrupted in June when a huge explosion at the mine in the Bili district killed two workers.
The latest explosion is the worst to hit Bali since the Baccu mine disaster in 2016, when a large fire broke out in the same area.
