Ngā Mata o te Upoko Tapahi:
He mata tapahi kei ngā pane tapahi o ngā mīhini keri kauhanga whakangungu rakau hei tapahi i ngā toka, i te oneone rānei i raro i te whenua. Ko te tikanga he mea hanga ēnei mata ki ngā koranu mārō nā te mea he tino pakari, he ātete hoki ki te pakaru, e āhei ai te mahi tonu i roto i ngā āhuatanga uaua o raro i te whenua.
Ngā Tapahi Kōpae Shield TBM:
He wāhanga nui ngā taputapu tapahi kōpae Shield TBM hei tautoko me te ārahi i te pane tapahi, hei whakarite kia maeneene te haere whakamua o te tukanga keri kōhao. Me whai āhuatanga ātete ki te kakahu me te waikura hoki ēnei taputapu tapahi kōpae, ka taea e ngā koranu te whakarato.
Ngā Nohoanga Tapahi Kōpae Cutterhead:
He maha ngā wā ka whakamahia he rauemi koranu hei pupuri i ngā mata o te cutterhead hei whakarite i te pumau me te roa o te mata.
Ngā Mīti Wiri me ngā Utauta Tapahi:
I ētahi mahi keri kōhao, ka whakamahia ngā mata wiri me ētahi atu taputapu tapahi. He maha hoki ngā wā ka whakamahia ngā rauemi koranu hei hanga i ēnei taputapu kia rawaka ai te kaha tapahi me te roa o te ora.
Ngā Āhuatanga
Te pakeketanga:
He tino mārō te āhua o ngā koranu, e mau tonu ana te mahi tapahi pumau i raro i te pēhanga teitei me te waku, ā, ka roa ake te roa o te ora o ngā taputapu.
Ātete Kakahu:
Ka pakaru kino ngā taputapu i te tapahi i ngā toka me te oneone i raro i te whenua. Mā te ātete ki te pakaru o ngā koranu ka taea e ngā mata me ngā taputapu tapahi te pupuri i te mahi tapahi whai hua i roto i ngā taiao uaua.
Ātete ki te Waikura:
Ka tūtaki pea ngā mīhini keri kōhao ārai ki te makuku, ki ngā matū waikura, me ētahi atu āhuatanga i raro i te whenua. Mā te ātete ki te waikura o ngā koranu ka tiaki i ngā taputapu mai i te kino.
Te Pūmautanga o te Wera:
I te wā e keri ana i te kōhao, ka puta te wera i ngā taputapu nā te waku. He pai te pumau o te wera o ngā koranu, ā, ka mau tonu te mahi ahakoa i roto i ngā āhuatanga pāmahana teitei.
Kaha:
He kaha nui ngā koranu i te nuinga o te wā, he mea nui tēnei hei tū atu ki ngā kaha tapahi me ngā kaha pānga.
Hei whakarāpopototanga, he mea nui te mahi a ngā koranu i roto i ngā mahi a ngā mīhini keri kōhao, ā, he āhuatanga pēnei i te ātete ki te kakahu, te ātete ki te waikura, me te pakeketanga kia pai ai te mahi i roto i ngā taiao uaua o raro whenua. He rerekē ngā momo koranu e whakamahia ana i runga i ngā whakaritenga hangarau me ngā āhuatanga rauemi.
