He rerekē ngā taputapu e rua o te mīhini pupuhi onepu Junda me te mīhini tango pere Junda. Ahakoa he rite te ingoa, he nui ngā rerekētanga o te whakamahinga. Heoi, hei karo i ngā hapa whiriwhiri a te kaiwhakamahi, hei pā ki te whakamahinga me te maumau moni, ka whakaurua ngā rerekētanga e rite ana i muri mai.
1, te rerekētanga i waenga i te pupuhi pupuhi me te pupuhi onepu
Ko te kaupapa o te tango i te hau me te pupuhi onepu he huarahi hei horoi i te mata o te hua mā te whakamahi i te hau hei mana. Ka whakamahia e te tango i te hau he mea whakakoi whakarewa, pērā i te pupuhi maitai, te onepu maitai, te pupuhi uku. Ka whakamahia te pupuhi onepu e ngā mea whakakoi kore-whakakoi whakarewa, pērā i te onepu korundum, te onepu karāhe, te onepu kapia me ētahi atu.
2, te pupuhi pupuhi me te tukanga pupuhi onepu a Junda
Ko te tukanga tango pere me te tango onepu e hangai ana ki ngā hua rerekē, te mahi me ētahi atu whakaritenga hei whakatau mena ka whakamahia te tango pere, te tango onepu rānei.
3. Te kōwhiringa o ngā taputapu pupuhi pupuhi me te pupuhi onepu
Hei tāpiri atu ki te whakakoi, he rerekē te whakamahi i te pupuhi me te pupuhi onepu, ā, he rerekē te taputapu whakaora whakakoi, he rite tonu ngā taputapu o ētahi atu taputapu. Ko te tikanga, ka taea hoki te whakamahi i ngā matūriki iti o te whakakoi hei taputapu whānui, ā, ko te tikanga, ka whakawhirinaki ki te āhuatanga tūturu.
4. Ko te pupuhi-ā-ringa he tikanga tango i te waikura whakarewa mā te whakamahi i te hau kōpeke, i te kaha ā-pūkaha rānei hei mana me te waku. Ko te whānui o te pere kei waenganui i te 0.2-2.5mm, ko te pēhanga hau kōpeke he 0.2-0.6mpa, ā, ko te koki i waenganui i te jet me te mata he tata ki te 30-90 nekehanga. He mea hanga ngā pūwero ki te maitai taputapu T7, T8 rānei, ā, he pakeke ki te 50-. Ko te roa o te mahi o ia pūwero he 15-20 rā. Ka whakamahia te pupuhi-ā-ringa hei tango i te unahi, te waikura, te onepu pokepoke me te kiriata peita tawhito mai i ngā hua whakarewa reo me te rahi me te matotoru kāore i te iti iho i te 2mm, i ngā wāhanga whakarewa me te hanga rānei kāore e hiahiatia he rahi me te āhua tika. He tikanga horoi tēnei i mua i te paninga mata (whakakikorua). He whānui te whakamahinga i roto i ngā wāhi hanga kaipuke nui, i ngā wheketere mīhini taumaha, i ngā wheketere motuka me ētahi atu. Ko te maimoatanga mata mā te pupuhi-ā-ringa, te kaha patu, me te pānga horoi e kitea ana. Engari mā te whakamahi i te pupuhi pupuhi o te mahi pereti angiangi, he māmā te hanga i te whakarerekētanga o te mahi, ā, ka pā te pupuhi maitai ki te mata o te mahi (ahakoa he pupuhi pupuhi, he pupuhi pupuhi rānei), ka rerekē te āhua o te rauemi turanga whakarewa, nā te mea kāore he kirihou, he kiri pakaru, he kiriata hinu rānei e rerekē ana me te rauemi turanga, nō reira, me te mahi hinu, ka kore e taea te tango katoa i te hinu i te pupuhi pupuhi pupuhi pupuhi.
5, he tikanga horoi ā-ringa anō hoki te onepū, engari ehara te onepū i te pupuhi pupuhi, he onepū te onepū pērā i te onepū kuata, he pereti whakarewa te pupuhi pupuhi. I roto i ngā tikanga maimoatanga mata o ngā mea mahi o nāianei, he nui ake ngā whakaritenga horoi o te horoi pupuhi onepu. He pai te pupuhi onepu mō te horoi i te mata o ngā mea mahi. Heoi, ko ngā taputapu pupuhi onepu whānui o Haina o nāianei he mea hanga ki te hononga, te waru, te ararewa peere me ētahi atu mīhini kawe onepū taumaha tawhito. Me hanga e ngā kaiwhakamahi he poka hohonu me te paparanga ātete wai hei tāuta mīhini, he nui ngā utu hanga, he nui ake ngā utu tiaki me te tiaki. Me te aro nui o te motu ki te tiaki taiao me te hauora ahumahi, nā te mea he nui te puehu e puta mai ana i te tukanga pupuhi onepu, ehara i te mea he parahanga kino ki te taiao, engari he ngawari hoki ki te arahi ki te mate mahi a te kaiwhakahaere (silicosis), he nui te pupuhi pupuhi hei whakakapi i te pupuhi onepu.
Ko te kōrero i runga ake nei mō te rerekētanga i waenga i te mīhini pupuhi onepu me te mīhini peening pupuhi, e ai ki tōna whakataki, ka taea e tātou te mārama ake ki te whānuitanga o te tono me ngā āhuatanga whakamahi o te taputapu, kia pai ai te whakamahi, kia tutuki ai ngā hiahia o te whakamahinga.
