Irgan referred to last week's accident in Mimika when the Big Gossan tunnel collapsed killing at least 28 people and 10 other injured.
The accident occurred when 40 workers held routine underground working security training in the tunnel.
The Big Gossan tunnel is not a mining tunnel as it has been used only for labor security training for the workers of the subsidiary of the US company Freeport-McMoRan.
Freeport has been in operation in Papua since the 1970, having the largest gold and copper mines in the country. (*/DWA)
