Ko te roa o te ngenge o ngā mekameka Armored Face Conveyor (AFC) he mea nui hei whakatau i te pono o ngā taputapu me te putanga waro i roto i te keri pakitara roa. Ko te AFC me ngā rahunga e pā ana ki te mekameka ka taea te take mō te 27% o te wā mutu katoa, me te taumahatanga mekameka keri koretake te take matua. Ka whakaratohia e tēnei pepa he rangahau hohonu ki ngā tikanga ngenge omekameka hononga porowhita me ngā mekameka hononga papatahi, arotake i ngā tikanga matapae ora matatau, ā, e tuku ana i ngā tohutohu hangarau kua whakaritea mō ngā kaihanga mekameka keri me ngā kaiwhakahaere maina waro. Ko te whāinga he whakarei ake i te roa o te ratonga mekameka keri mā te arotau hoahoa, te aroturuki matatau, me ngā rautaki tiaki pūtaiao, kia pai ai te whakaputa.
- Ngā Mekameka Hononga Porowhita: He hoahoa ōrite, he ngāwari hoki. Heoi, ko te iti o te wāhi pa i waenga i ngā hononga ka hua ake he ahotea pa nui me te pakaru ā-rohe.
- Ngā Mekameka Hononga Papatahi: Ko ngā hononga i roto i ngā pūnaha hononga papatahi ka tautuhia hei ngoikoretanga nui. E whakaatu ana te Tātari Huānga Mutunga Kore (FEA) ka aro te ahotea i roto i ngā hononga papatahi ki te pakihiwi hononga, te piko o waho, me te ringa tika o roto. I raro i ngā kawenga ōrite, ka tata ki te 1.9 ngā wā ka rerekē te āhua o ngā hononga papatahi i ō ngā hononga porowhita, ka nui ake te aro ki te kakahu ā-rohe.
2.2 Ngā Tikanga Rahunga Tuatahi
Ko te ngoikore o te ngenge ka puta mai i ngā pānga o te ahotea ā-pūkaha, te kakahu, me te pirau o ngā rauemi:
- Pakaru o te Ngenge: Ka tīmata ngā pakaru iti i ngā pūwāhi kukū ahotea nā te kawenga huringa (hei tauira, ngā pūwāhi whakapā i ngā hononga porowhita, ngā pūtake niho hononga i ngā hononga papatahi), ka hua ake he pakaru pakarukaru. E whakaatu ana ngā rangahau ka tino whakarerekē te kakahu i te āhua o te hononga, ka whakanui ake i te kukū ahotea, ā, ka waihanga i tētahi huringa "ngenge-kakahu" kino.
- Te Pakarutanga Ārai: Ko te tikanga pakaru matua e hua ake ai te ngaronga o te wāhanga whakawhiti me te whakahekenga o te kaha. Kei ngā hononga hono, te mata pewa o waho, me te taha o waho o ngā wāhanga tika ngā rohe pakaru nui.
- Te Utaina Nui me te Pānga: Ko te utaina nui ohorere mai i te hurihanga o ngā āhuatanga o te mata (hei tauira, te piri) ka puta he āhua rerekē, he whati rānei o ngā hononga mekameka.
2.3 Ngā Tikanga Matapae Ora Matatau
He mea nui te matapae a te rorohiko mō te rangahau me te whanaketanga i nāianei.
- Tātari Huānga Mutunga Kore (FEA): Ka tatau tika i te tohatoha o te ahotea tauutuutu ōrite i raro i te kawenga, ka whakaputa mahere āhua ora hei tautuhi ā-kanohi i ngā ngoikoretanga. Ka whakaūhia e ngā rangahau te kaha o te FEA ki te matapae i te roa o te ngenge o te mekameka hononga porowhita.
- Ngā Tauira Ariā Kino: Ka whakamahia te Ariā Kino Whakaemi Raina (hei tauira, te Ture a te Kaimaina) me te Ariā o te Ritenga Whakawhanaungatanga o te Kino ki te whakatauira i te oranga o te mekameka maina. Mā te whakatū hononga ki ngā tukanga kino e mōhiotia ana, ka tukuna he tauira pāngarau whai hua mō te aromatawai i te oranga o te mekameka hononga porowhita i raro i ngā irahiko kawenga matatini.
- Te Arotautanga o te Āhua me te Whakamāmā i te Whakamahinga: Whakamahia te arotautanga ā-āhua e whakahaerehia ana e te FEA mō ngā hononga mekameka me ngā hononga (ina koa ngā niho hononga hononga papatahi) kia tutuki ai te tohatoha ahotea ōrite. Whakamanahia te ōritetanga me te whaitake o te roa o te ora ngenge i roto i ngā hoahoa kua arotauhia mā te tatau.
- Te Pūtaiao Rauemi me te Auahatanga Maimoatanga Wera: Mā te whakanui ake i te ihirangi o ngā huānga whakarewa (Cr, Ni, Mn, Mo) me te whakamahi i te maimoatanga wera kua arotauhia (hei tauira, te tinei me te whakamahana) ka taea te whakanui ake i te ātete kakahu mā te 10-25%. Mō ngā āhuatanga tino kino, me whakaaro ki ngā paninga motuhake (hei tauira, te ārai-waikura) me ngā tohu kowiri tira.
- Te Pūmautanga o te Hononga: Me tutuki i ngā hononga ngā whakaritenga kaha teitei, te wetewete, me te honohono. Me piri pū ngā hoahoa ki ngā paerewa pēnei i te DIN 22258-3, me te arotahi ki te whakatutuki i te tohatoha taumahatanga ōrite puta noa i ngā whirihoranga maha-niho—he mea nui ki te pono o te pūnaha whānui.
3.2 Mō ngā Kaiwhakahaere Maina Waro: Te Aroturuki Atamai, te Tiaki, me te Hoko
- Whakatinanahia te Aroturukitanga Taumahatanga o te Mekameka Keri Maamaa: Kāore i te tino tika ngā tikanga tuku iho e whakatau ana i te taumahatanga mai i te ia o te motuka. E taunakihia ana kia whakamahia ngā mita taumahatanga ipurangi kua tāutahia ki ngā pae rere hei aroturuki i te tohatoha taumahatanga wā-tūturu puta noa i te mata. He mea nui te whakauru i ēnei raraunga ki te pūnaha whakahaere pakitara roa mō te whakahaere taumahatanga aunoa hei ārai i te taumahatanga nui rawa atu, iti rawa rānei.
- Whakatūria he Pūnaha Tiaki Matapae: Whakawhanakehia he tauira matapae mō te toenga o te mekameka keri mā te whakauru i ngā raraunga kume wā-tūturu, te tana whakaputa hītori, me ngā tirotiro ā-ahu auau o ngā rohe pakaru hononga. Mā tēnei ka taea te whakarite i te whakakapinga mekameka pūtaiao, ka karo i te whakakapinga wawe me te rahunga nui.
- Rautaki Hoko me te Whakahaere mō ngā Mata Tino Roa: Mō ngā taputapu mata neke atu i te 400 mita, ko te tautuhi i ngā huihuinga mekameka-me-rere māmā, te whakahaere tukutahitanga maha-puku atamai, me ngā pūnaha kawe pono teitei me noho hei whakaritenga hangarau matua hei aro atu ki ngā wero pēnei i te kaha kore-kawenga teitei, te tīmatanga uaua-kawenga taumaha, me te tere o te pakaru.
