1.Hoʻohana ʻia kēia kaʻa e ka uila a ʻaʻohe ona hoʻokuʻu ʻana i ka ʻōpala, ʻaʻole ia e hōʻemi wale i ka haumia i kahana ʻeli ʻanake kaiapuni akā hana pū kekahi i kahi ʻano hana olakino no nā limahana. Eia kekahi, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka uila ma mua o ke kumukūʻai o ka wahie. Hiki i ka hoʻohana lōʻihi ke mālama i nā ʻoihana i kahi nui o nā kumukūʻai ikehu. I kēia manawa, ʻoi aku ka maʻalahi o ka mālama ʻana i nā kaʻa mining uila, me ka liʻiliʻi o ka ʻaʻahu ʻana i nā ʻāpana, e hōʻemi hou ana i nā kumukūʻai hana.

Hana ikaika, hiki ke lawelawe maʻalahi i nā kūlana alanui paʻakikī ma nā wahi eli. Inā piʻi i nā mauna a i ʻole ke kaʻa ʻana ma nā alanui ʻinoʻino, hiki iā ia ke hoʻopuka i ka mana me ka paʻa, e hōʻoiaʻiʻo ana i ka hoʻopau pono ʻana i nā hana halihali. Ke hoʻohālikelike ʻia me nā kaʻa eli wahie kuʻuna, ʻoi aku ka wikiwiki o ka pane mana o nā kaʻa eli uila, ka hoʻomaka ʻana a me ka wikiwiki, e mālama pono ana i ka manawa halihali.

3.ʻŌmole i hoʻopaʻa ʻia me ka paipu huinahā, hoʻomāmā pālua, puna papa mānoanoa 13, mau kaila mining kūikawā, hiki ke piʻi ikaika, ʻaʻohe pono e hopohopo e pili ana i nā pilikia mana, mana piha, pahu ukana i hoʻopaʻa ʻia me ka papa kila ikaika kiʻekiʻe, hāmeʻa hāpai hydraulic aunoa, kūlana hilinaʻi, paʻa a paʻa.

Inā paha ma nā lua eli honua me kahi palena a i ʻole nā ​​lua eli ākea i piha i nā mea hana, hiki ke hiki maʻalahi a me ka manuahi i nā wahi i koho ʻia, e hoʻomaikaʻi nui ana i ka maʻalahi a me ka maʻalahi o nā hana, a ʻaʻole e kaupalena hou ʻia ka hana halihali e nā palena o ka pūnaewele. Hiki i ka halihali ʻana i ka ʻaihao ma lalo o ka honua a me ka wehe ʻana i ka ʻōpala ke huli maʻalahi, hele ma waena o nā tunnels lalo o ka honua haiki, a hoʻoponopono i nā ʻāina paʻakikī a me nā pali o lalo o ka honua.

5.Ma ke ʻano o ka hoʻolālā palekana, ua lako nā kaʻa mining me nā mea palekana palekana like ʻole, e like me nā ʻōnaehana braking hilinaʻi, nā hale paʻa paʻa, nā ʻōnaehana hoʻokuʻu paʻa, a me nā mea ʻē aʻe, e hōʻoia pono ana i ka palekana i ka wā o ka lawe ʻana. He ʻoluʻolu a hilinaʻi hoʻi ka ʻōnaehana braking, hiki ke hoʻokuʻi koke i nā kūlana pilikia e pale aku i nā ulia; Hana ʻia ke kiʻi me ke kila ikaika kiʻekiʻe, paʻa a paʻa, hiki ke kū i nā ukana kaumaha a me nā puʻupuʻu; Hiki i ka ʻōnaehana hoʻokuʻu ke hōʻemi pono i ka haʻalulu o ke kaʻa i ka wā o ka hoʻokele ʻana, e hōʻoia ana i ka lawe maʻalahi ʻana o nā waiwai. Eia kekahi, ua hana ʻia ke kaʻa i ka nānā pono ʻana i ka maikaʻi a me ka hoʻāʻo hilinaʻi, me ka hana paʻa, ka haʻahaʻa o ka hāʻule ʻana, a hiki ke hana mau no ka manawa lōʻihi, e hāʻawi ana i ke kākoʻo ikaika no ka hana mining. Hoʻonohonoho akamai, hana pono.
