Nā te korenga o te pūngao o te ao, kua nui haere te aro ki te whakamahinga pūngao i roto i te tukanga kuru. Mai i te taenga mai o te mira roera pēhanga-teitei i te mutunga o te tekau tau atu i 1980, kua whakamahia nuitia i roto i te umanga sima me ngā maina konganuku kore-ferrous takitahi. Kua whai hua te umanga sima i tēnei taputapu tino whai hua e penapena ana i te pūngao me te whakamahinga maitai.
He nui te nui o ngā konganuku i kuruhia i roto i te mahi whakarewa me te keri, ā, he uaua te huri i te nuinga o ngā konganuku whakarewa. I tēnei wā, he nui te raru o te whakapaunga pūngao, te whakapaunga maitai me te whai huatanga o ngā mira pōro, ā, he tino pāngia hoki te tere whakaora o ngā kohuke e te tikanga huri. He whānuitia te whakamahinga o te mira roera pēhanga teitei i roto i te umanga whakarewa me te keri, ā, kei te taumata rangatira o te ao. Ko te hua tēnei o te tūhuratanga me te mahi tonu a ngā kaihanga taputapu o te whare i ngā tau tata nei, ā, kua angitu te mutunga.

Ko te rerekētanga i waenga i te mira roera pehanga teitei me ngā taputapu kuru tuku iho
He tino rite te āhua o te mira rōra pēhanga teitei ki te mira rōra takirua tuku iho, engari e rua ngā rerekētanga o te ngako.
Ko tētahi ko te whakamahinga o te mira rōra pēhanga-teitei he kuru āhua-pūmau, e penapena ana i te 30% o te whakapaunga pūngao ki te whakataurite ki te kuru pānga;
Tuarua, ka whakatinanahia e ia te kuru paparanga rauemi mō ngā rauemi, arā, te kuru tahi i waenga i ngā rauemi me ngā rauemi, me te tino pai o te kuru, ā, ka taea te whakarite i te ahotea whakaputa i waenga i ngā rauemi mā te pēhanga roera. E rua ngā roera e hurihuri ana tetahi ki tetahi, ko tētahi he roera pumau, ko tētahi he tawhiti ka taea te whakarite. Ko te pēhanga i waenga i ngā roera ka taea te eke ki te 1500 ki te 3000 hau, ā, ka taea e ngā hua kuru te eke ki te 2mm, ka puta he "kuru nui ake, he iti ake te kuru" ā, ka noho hei momo taputapu kuru hou e whakakapi ana i te kuru ki te kuru. Nā tōna kaha kaha, ehara i te mea ka kuru noa i te rauemi, engari ka pakaru hoki te hanganga o roto o ngā matūriki rauemi, ā, ka tino whakapai ake i te kaha o te kuru.
Ko te mira roera pēhanga teitei he mea tito mai i te taputapu whāngai hiko, te taputapu aukati rauemi, te taputapu taraiwa, te taputapu uta waipēhi, te taputapu tautoko, ngā wāhanga roera hihiri me te pateko, me ētahi atu.

I roto i ēnei, ko te ihirangi o ngā rauemi i roto i te 0.2mm ka eke ki te 30%-40%, ko te rauemi o tēnei taumata pai ka taea te whakatutuki i ngā whakaritenga whakarōpū konganuku i te nuinga o te wā, nō reira mō tēnei momo hua, ka taea te whakahaere i te mahi whakarōpū i muri tonu i te whakarōpūtanga.
I taua wā anō, i roto i te tukanga whakamahi i te mira rōra pēhanga-teitei mō te whakangawari i te konganuku me te whakaputa kuru konganuku, i raro i te mahi a te pānga taha o te rauemi, ka noho he wāhanga iti o ngā matūriki konganuku he nui rawa te rahi o te matūriki ki roto i te keke whakaputa. Mena ka whakamahia tika tēnei wāhanga i te wā o te huri, te whakangawari rānei, ka tino rerekē te rere o te mahi e pā ana, ka pā kino ki te whakaputanga whakangawari.
Nō reira, i roto i te tukanga whakaputa pai mā ngā taputapu mīhini, hei karo i ēnei raruraru, me whakahaere he tirotiro porowhita kati o te keke rauemi i muri i te tukatuka whakaputanga e te mira roera pēhanga-teitei. Mā tēnei, ka taea te whakahaere tika i te rahi o te matūriki o te hua i roto i te keke kia kore ai e rerekē te tukanga i puta mai i te whakaurunga o te konganuku he nui rawa te rahi o te matūriki ki roto i te mahi mira pōro. Ā, ka taea hoki te whakauru tika ki roto i te tukanga whiriwhiri. Mā tēnei tikanga, e kore e taea anake te whakaiti i te nui o te konganuku e whāngai ana i roto i te tukanga mira pōro, engari ka ārai hoki i te huri nui rawa o ngā konganuku pai, kia pai ake ai te whai huatanga me te kounga o te pai.
