Me pēhea te whakamahi i te wiri kohatu
He mīhini keri māmā, māmā, ā, he ohanga te keri toka, e whakamahia whānuitia ana i roto i te hanga rori, te hanga hanganga, te keri maina me ētahi atu ahumahi. He mīhini nui tēnei i roto i te keri kohatu. He taputapu pānga te keri toka, ā, me whakamahi i te hinu, te wai me te hau hei whakamahi me ngā momo rauemi āwhina, ā, he nui ngā tono mō te pono me te haumaru o ngā taputapu; i tētahi atu taha, he uaua hoki te whakahaere me te tiaki i ngā taputapu. Ehara i te mea he mea nui te whakamahinga pūtaiao me te tiaki i ngā keri toka hei whakarite i te haumaru o te hanga me te ārai i ngā aituā kino, engari hei whakapai ake hoki i te mahi, te roa o te mahi me te whai huatanga o te hanga o ngā taputapu.
Te mahi whakarite i mua i te tīmatanga o te mīhini
1, Ko ngā keri toka hou kua hokona ka pania ki te hinu ārai-waikura he matotoru teitei, ā, me wetewete mārama i mua i te whakamahinga. I te wā e huihui ana, me pania ia wāhanga e neke ana ki te hinu whakahinuhinu. I muri i te huihuinga, honoa te keri toka ki te raina pēhanga, whakatuwherahia te mahi hau iti, ka tirohia mēnā he pai te mahi.
2, Werohia te hinu whakahinuhinu ki roto i te mīhini werohanga hinu aunoa, ko te hinu whakahinuhinu e whakamahia whānuitia ana ko te 20#, 30#, 40#. Me horoi te ipu hinu whakahinuhinu, me hipoki, kia kore ai e uru te paura toka me te paru ki roto i te mīhini werohanga hinu.
3, Tirohia te pēhanga hau me te pēhanga wai o te wāhi mahi. Ko te pēhanga hau he 0.4-0.6MPa, ki te nui rawa ka tere ake te pakaru o ngā wāhanga mīhini, ki te iti rawa ka whakaiti i te whai huatanga o te keri toka, ā, ka waikura hoki ngā wāhanga mīhini. Ko te pēhanga wai he 0.2-0.3MPa te nuinga, ki te nui rawa te pēhanga wai ka whakakīia ki roto i te mīhini ka whakangaro i te hinu whakahinuhinu, ka whakaiti i te whai huatanga o te keri toka, ā, ka waikura hoki ngā wāhanga mīhini; ki te iti rawa ka ngoikore te pānga horoi.
4, Ahakoa e tutuki ana te toka hau i ngā whakaritenga kounga, kāore e whakaaetia te whakamahi i te toka hau kāore i te whai tohu.
5, me whakakī te urunga o te paipa hau ki te keri toka, kia kati ai te paru e pupuhi ana. Mō te moni mai i te paipa wai, kia horoia te paru i te hononga kia kore ai e pakaru, me whakakī te paipa hau me te paipa wai kia kore ai e taka, e whara ai te tangata.
6, Whakauruhia te hiku o te paraihe ki te pane o te wiri toka, ka huri te paraihe kia tika ki te taha matau. Ki te kore e huri, ko te tikanga he mea e piri ana te mīhini, ā, me whakatika i te wā tika.
7, Whakakīia ngā pūtu hononga, ka tirohia te mahi a te poroporo ina tahuri te hau, ā, ka taea anake te tīmata te mahi ina mahi noa.
8. Me whakatū te keri toka arataki, ā, me tirotiro te mahi a te porotiti, me tirotiro hoki te keri toka waewae-hau me te keri toka whakarunga. Me tirotiro hoki ngā keri toka whakarunga i te ngāwari o ō rātou waewae-hau, me ētahi atu.
9. Me whai hiri pai te pūnaha waipēhi i ngā keri toka waipēhi kia kore ai e poke te hinu waipēhi, kia mau tonu ai hoki te pēhanga o te hinu waipēhi.
Ngā whakatūpato i te wā e mahi ana
1. I te wā e keri ana, me āta hurihuri, ā, kia tae te hohonutanga o te kōhao ki te 10-15mm, kātahi ka āta huri ki te mahi katoa. I roto i te tukanga keri toka I roto i te tukanga keri toka, me hanga te tokotoko whakakoi kia neke tika i roto i te rārangi tika e ai ki te hoahoa o te kōhao, ā, kia whakanohoia ki waenganui o te kōhao.
2. Me whakamātautau te pana o te pou i te wā e keri ana i te toka. Mēnā he iti rawa te pana o te pou, ka peke whakamuri te mīhini, ka piki ake te wiri, ā, ka whakaitihia te whai huatanga o te keri toka. Mēnā he nui rawa te pana, ka whakakīkīhia te pēhi i te raro o te kanohi, ā, ka oma te mīhini i raro i te taumaha rawa, ka pakaru wawe ngā wāhanga, ka whakaroa hoki i te tere o te keri toka.
3. Ina mau te wiri toka, me whakaiti te pana o te rakau, ā, ka taea te huri haere noa. Ki te kore e whai hua, me whakamutu tonu. Whakamahia te kī hei huri mārire i te toka hau, kātahi ka whakatuwhera i te pēhanga hau kia huri mārire te toka hau, ā, kaua e patuki i te toka hau.
4、Mātakihia te āhua o te paura e tukuna ana i ngā wā katoa. Mēnā he noa te paura e tukuna ana, ka āta rere te paru me te pūwheratanga o te kōhao; ki te kore, pupuhihia te kōhao kia kaha. Mēnā kāore anō kia whai hua, tirohia te kōhao wai o te rākau whakakoi me te āhua o te hiku whakakoi, kātahi ka tirohia te āhua o te ngira wai, ka whakakapia ngā wāhanga kua pakaru.
5, me āta tirotiro te wāhi e rongoa ai te hinu me te wāhi e tukuna ai te hinu, me te whakarerekē i te nui o te hinu e werohia ana. Mēnā kāore he hinu e whakamahia ana, ka ngāwari te pakaru wawe o ngā wāhanga. Mēnā ka nui rawa te hinu whakahinuhinu, ka poke te mata mahi.
6, me aro te mahi ki te tangi o te mīhini, me te tirotiro i tana mahi, me te kimi i te raruraru, me te whakatau i te wā tika.
7, Kia aro ki te āhua mahi o te oumu, ā, me whakakapi i te wā e kitea ana he rerekē.
8. I te wā e whakahaerehia ana te wiri toka whakarunga, kia tūpato ki te nui o te hau e tukuna ana ki te waewae hau kia kore ai e piki, e heke rānei te wiri toka, ka puta he aituā. Me pono te pū tautoko o te waewae hau. Kaua e pupuri rawa i te mīhini, kaua hoki e eke ki runga i te waewae hau kia kore ai e whara, e pakaru rānei te mīhini.
9,9. Kia tūpato ki te āhua o te toka, kaua e pokaia ngā papa, ngā hononga me ngā kapiti, kaua e pā ki ngā kanohi toenga, ā, me tirotiro tonu mēnā he tūponotanga kei te hipokihia te tuanui me te whāriki.
10,10,Kia whai hua ai te whakamahi i te mahi poka tuwhera. I roto i te mahi keri, he hononga nui ko te whakatuwheratanga o te poka, ka mahia te whakatuwheratanga o te poka me te whakaiti i te pēhanga me te pēhanga pana pumau. Me iti te pēhanga pana kia taea ai te whakatuwheratanga o te poka i runga i te mata toka he nui te piko. Ka mahia te keri me te pēhanga pana iti me te pēhanga pana pumau.
