ʻO ka Otter Juan nickel mine kekahi o nā mines kahiko loa ma ka ʻāina ʻo Kambalda ma Western Australia, ma kahi o 630 mau kilomita ma ka hikina o ke kūlanakauhale ʻo Perth. Ma hope o ka pani ʻia ʻana no ka manawa pōkole a kūʻai maikaʻi ʻia, ua mālama ʻia ka ʻoihana ʻo Otter Juan mine e Goldfields Mine Management no kekahi mau makahiki. Me nā hana ma mua o 1,250 m ma lalo o ka ʻili, ʻo ia kekahi o nā mines hohonu loa ma Western Australia.
ʻO nā kūlana maʻamau i loko o ka maina e unuhi i ka mineral pentlandite, ʻo ia ka pūhui nickel sulfide a loaʻa ma kahi o 4% nickel, paʻakikī loa. He wahi koʻikoʻi ko ka lua a me ka talc chlorite ultramafic e kau ana i ka pā pōhaku nui. Lawe ʻia ka ʻiʻa i ʻeli ʻia i ka Kambalda Nickel Concentrator no ka hana ʻana.
ʻOi aku ka paʻakikī o nā kūlana lepo pilikia ma ka mine ʻo Otter Juan e ka hoʻonui ʻana i nā hana seismic. No laila, ua koho ʻo Goldfields Mine Management e hoʻohana i ka OMEGA-BOLT maʻalahi me ka hiki ke lawe i ka ukana o 24 tons e hoʻopaʻa i nā ʻili o ka ʻili. Ma muli o kona mau waiwai kino, ua koho mua ʻia ka OMEGA-BOLT no ka hoʻohana ʻana i nā ʻāpana mining seismically active, no ka mea, hāʻawi ia i kahi kiʻekiʻe o ka deformability e hoʻokipa i ka neʻe ʻana o ka honua.
