Nā pahi ʻokiʻoki:
Ua lako nā poʻo ʻokiʻoki o nā mīkini ʻokiʻoki pale me nā pahi no ka ʻokiʻoki ʻana i nā pōhaku a i ʻole ka lepo ma lalo o ka honua. Hana ʻia kēia mau pahi me nā mea hao paʻakikī ma muli o ko lākou paʻakikī maikaʻi loa a me ke kūpaʻa ʻana i ka ʻaʻahu, e hiki ai ke hana mau i nā kūlana paʻakikī o lalo o ka honua.
Nā mea ʻoki diski pale TBM:
ʻO nā mea ʻoki diski Shield TBM he mau ʻāpana koʻikoʻi e kākoʻo a alakaʻi i ke poʻo ʻokiʻoki, e hōʻoiaʻiʻo ana i ka holomua maʻalahi o ke kaʻina hana tunneling. Pono pū kēia mau mea ʻoki diski i nā waiwai kūpaʻa i ka ʻaʻahu a me ka pale ʻana i ka pala, hiki i nā alloys ke hāʻawi.
Nā Noho ʻoki Disc Cutterhead:
Hoʻohana pinepine ʻia nā noho no ka hoʻopaʻa ʻana i nā pahi ʻokiʻoki ma kahi e hoʻohana ai i nā mea hao e hōʻoia i ke kūpaʻa a me ka lōʻihi o ka pahi.
Nā ʻāpana wili a me nā mea hana ʻokiʻoki:
I kekahi mau hana tunneling pale, hoʻohana ʻia nā ʻāpana wili a me nā mea ʻoki ʻē aʻe. Hoʻohana pinepine ʻia ka hana ʻana o kēia mau mea hana i nā mea hao e hōʻoia i ka lawa ʻana o nā hiki ke ʻoki a me ke ola.
Nā ʻano
Paʻakikī:
Hōʻike nā ʻāpana hao i ka paʻakikī koʻikoʻi, e mālama ana i ka hana ʻoki paʻa ma lalo o ke kaomi kiʻekiʻe a me ka friction, a pēlā e hoʻolōʻihi ai i ke ola o nā mea hana.
Ke kū'ē ʻana i ka ʻaʻahu:
ʻO ka ʻoki ʻana i nā pōhaku a me ka lepo ma lalo o ka honua e hōʻeha nui ai i nā mea hana. ʻO ke kūpaʻa ʻana o nā metala hao e hiki ai i nā pahi a me nā mea hana ʻoki ke mālama i ka hana ʻoki maikaʻi i nā wahi ʻino.
Ke kū'ē ʻana i ka palaho:
Hiki i nā mīkini hana tunneling pale ke hālāwai me ka makū, nā mea ʻino, a me nā mea ʻē aʻe ma lalo o ka honua. Kōkua ke kūpaʻa ʻana o nā alloys i ka pale ʻana i nā mea hana mai ka hōʻino ʻia.
Paʻa Wela:
I ka wā o ke eli ʻana i ka tunneling, hoʻopuka nā mea hana i ka wela ma muli o ka friction. Loaʻa i nā alloys ke kūpaʻa wela maikaʻi, e mālama ana i ka hana mau ʻoiai i nā kūlana wela kiʻekiʻe.
Ikaika:
Loaʻa i nā alloys ka ikaika kiʻekiʻe, he mea nui ia no ke kū ʻana i nā ikaika ʻoki a me ka hopena.
I ka hōʻuluʻulu manaʻo, he kuleana koʻikoʻi ko nā mea hoʻohuihui i nā noi mīkini hana pale, e hāʻawi ana i nā ʻano e like me ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa ʻana i ka pala, a me ka paʻakikī kiʻekiʻe e hōʻoia i ka hana pono ma nā wahi paʻakikī o lalo o ka honua. Hoʻohana ʻia nā ʻano mea hoʻohuihui like ʻole ma muli o nā koi ʻenekinia kikoʻī a me nā waiwai mea.

Hoʻohana ʻo Kimberly Carbide i nā lako hana ʻoihana holomua, kahi ʻōnaehana hoʻokele akamai, a me nā hiki hou kū hoʻokahi e hāʻawi i nā mea kūʻai aku honua ma ke kahua lanahu me ka ʻike loea ikaika a me kahi kaʻina hana VIK ʻEkolu-Dimensional piha. He hilinaʻi nā huahana i ka maikaʻi a hōʻike i ka hana maikaʻi loa, me ka ikaika ʻenehana kupaianaha i loaʻa ʻole i nā hoa like. Hiki i ka hui ke hoʻomohala i nā huahana e pili ana i nā pono o ka mea kūʻai aku, a me ka hoʻomaikaʻi mau ʻana a me ke alakaʻi loea.
