Te Mārama ki te Keri DTH: He Aratohu mō te Tīmatanga ki te Hangarau Tuturu

I roto i te ao uaua o te keri, te keri pari, me te hanga whare, ehara te whai huatanga i te whāinga noa iho—he mea nui hoki. I roto i ngā tikanga maha e whakamahia ana hei wero i te toka mārō,Te keri i raro i te poka (DTH)he kōwhiringa tino pai mō ngā poka pupuhi hohonu, tika hoki.

Engari he aha tonu te mea e tupu ana i raro i te mata? Mena he hou koe ki te umanga, ka whakamāramahia e tēnei aratohu ngā tikanga, ngā painga, me ngā wāhanga nui o te hangarau DTH.

He aha te DTH Drilling?

I tōna pūtake,Te keri DTHhe pūnaha patupatu. He rerekē ki te keri Top Hammer, e whakaputahia ana te kaha pānga ki runga ake i te whenua ka panaia mā roto i ngā tokotoko keri,Ka whakatakotoria e te DTH te hama ki muri tonu i te mata wiri.

E ai ki te ingoa, ka "heke te hama ki raro i te kōhao." Ko te tikanga ka pā te mana patu ki te mata o te toka, ahakoa te hohonu o te kōhao.

Te Mahi a te Tukanga: Ngā Nekehanga Matua e Toru

Te keri DTHe whakawhirinaki ana ki tētahi huinga tukutahi o ngā mahi ā-pūkaha e toru:

1. Pānga (Patupatu):Ka peia e te hau kōpeke he piston ki roto i te hama, ka pā ki te tuara o te mata wiri mano ngā wā ia meneti.

2. Hurihanga:Ka hurihia te aho o te mīhini keri i runga i te mīhini keri, kia mōhio ai ka pā ngā pātene carbide o te mata keri ki te toka hou i ia whiunga.

3. Whāngai (Pēhanga):Mā te pēhanga tonu ki raro ka noho te mata o te kohatu ki te pa atu, ka nui ake te whakawhiti pūngao.

Te Tūranga o te Hau:Haunga te whakakā i te hama, he mahi tuarua, he mahi nui hoki tā te hau kōpeke:te horoiKa haere mā roto i ngā tokotoko keri, ka puta ki te mata o te moka, ka pupuhi i ngā haehaenga toka (te puehu me ngā maramara) ki runga ki te mata.

He aha i whiriwhiri ai i te DTH i runga i ētahi atu tikanga?

He maha ngā take e pai ake ai ngā tohunga o te umanga ki te hangarau DTH:

• Te Tika me te Tika:Nā te mea ka puta te pānga i te pūwāhi e pā ana, he iti ake te ngaronga pūngao me te pekapeka o te kōhao ki te whakataurite ki ngā pūnaha hama-runga.

• Te Āheinga o te Pūnga Hōhonu:Ko te DTH te paerewa koura mō te keri hohonu (neke atu i te 20 mita) nā te mea kāore e hiahiatia te kaha patu kia haere mā roto i tētahi aho roa o ngā tokotoko.

• Ngā mahi maha:He tino pai tēnei mea mō ngā hanganga toka waenga, mārō hoki, nō reira he mea nui mō te keri poka tuwhera me te keri puna wai.

• Te Whai Hua o te Pūngao:Ko te pānga tika he iti ake te pakaru me te haehae o ngā rakau wiri me ngā hononga, ā, ka iti ake ngā utu tiaki i te roanga o te wā.

Ngā Wāhanga Matua o te Aho DTH

Hei whakaoti i te mahi, me whai i te whakaritenga paerewa o te DTH:

• TeHama DTH:Te "mīhini" o te mahi.

• TeMomo DTH:Ko te taputapu tapahi, he mea whakauru ki ngā pātene tungsten carbide.

• Ngā Rakau Wiri (Ngā Ngongo):Mā ēnei ka puta te hurihanga me te ara hau.

• TePūhiko:Ko te whare hiko e whakarato ana i te hau pēhanga teitei.

Ētahi Whakaaro mō te Hunga Tīmata

Te whiriwhiri i te tikaNgā taputapu DTHHe nui te whakawhirinaki ki te momo toka me te whānui o te kōhao e hiahiatia ana. Ahakoa he pakari te hangarau, ko te angitu kei te taurite i ō tautuhinga pēhanga hau ki te hoahoa mata tika.

I te mea ka nui haere te wero o ngā taiao keri, ka whanake tonu te hangarau DTH, ka tere ake te uru me te whakamahi wahie atamai ake mōngā waka hou.
