Kua puta te Whakatetehi Awa hei tūranga whakarerekē i roto i te whenua o ngā mahi whakatetehi, whakawhitiwhiti atu i ngā hiranga kore rawa atu me te mōhiotanga mo ētahi atu whakamahinga. E pīari ana i te hā o te hau, e whakapakiri ana tēnei rautaki hou i te kawe pūngao me te kawe porowhita ki runga i te whakangungu ake i te whakatetehi i ngā hua kiko nui pērā i te waipapa me te koneti.
Ka mahi te Whakarere Pūngao i runga i tētahi kaupapa iti noa iho, engari whai hua. Ko te hā pūngao (ī raro i te 0.4–0.7 MPa) e whakahaere ana i te pihinga o te pihikara, whakaputa mai i te kōwhiri ā-wāhi nui. Ka whakawhiti tēnei kōwhiri ā-wāhi ki te karu whakamahi ki te Tāhura , ahakoa ko te mōhiotanga whakatetonga e whakaatu ana i te taura ki te tahuri i ngā roa hei whakamahana i ngā whenua kōwhatu nui. Ko te waewae pūngao, e whakahaere ana i te whanaketanga me te whakapakuhia i te hā, ka whakamua tonu i te karu whakamahi, ka whakanui i te hua o te mahi whakamahi.
Ko te Pūhiko Rereāni Awaheke i whakatupuia hei mea mohio, ā, e whai wāhi ana i runga i ētahi atu hekenga. I te mahi kōwhai, ko tērā te pai tōna whakamahi mo te whakawehenga rereāni me te pūhiko pūtauheke i ngā whenua kōwhai iti ki ngā whenua kōwhai nui. Mo te hanganga herehere rereāni, ka whakamahia hei pūhiko pūtauheke me ngā pūtauheke here i ngā rua rererangi me ngā rua huarahi. Ki te hanga, ko tērā te pai tōna whakamahi mo te whakariterite pūtake me te whakahaere i ngā wharepaku konakona. Ko ia hoki te whaiaro mo te whakatika tahataha me te pūhiko pūtauheke pūtake o ngā tāhuhu i ngā kaupapa wai me ngā kaupapa haere.
Kei te tuku ngā hiranga matatika o te Wero Pūhau Rangi. Ki te āheititanga pūhau i runga i te 2000 putanga ki te meneti, ko te torotoro taiao nui e taea ai. Ko tana whakamua pūhau ake tonu i raro i te kawe hokohoko, ka whiwhi anō he paihere mahi. E taea ana te wero i ngā waewae kōwhatu me te mōhiotanga Pugh f=8–18, ka taea hoki te mahi i ngā wheako rerekē, inaianei ngā wheako tuarua me ngā tūnga pūmau. Ka taea hoki e ia te whakatupu i ngā āhuatanga whakamātau, pērā i te wai me te hū.
Ko te pou whakauru here ki te kahu e whakaae ana i te ringa tuatahi ki te whakarerekē i te kōwhiri ā-wāhi me te rahuitanga. Ko te waewae pūngao e taea ana te whakatika i te uiuinga paihere hei whakarite i ngā uiuinga mahi rerekē. Ko te hoahoa hangarau e awhina ana ki te waihanga anō, ki te whakakapi anō me te whakakapi anō i ngā momo matua. Ko te rākau mōhiohia tonu e tiaki ana i te whakakore, e whakatōpu ana i te Te mahi wā o te whakamahi.
Ki te whakarite i ngā tahinga iti me ngā tūanga waiwhakaara, ko te Air Leg Rock Drill e tae ana ki ngā ture hōngongoi ā-rorohiko, mēnā ka taea te whakangungu i te mahi. Ko tana hīrahi haere pneumatic anake, kāore i te pūmau i ngā taueke, nā tērā ka pai ai ki te whakamahi i roto i ngā wāhi kapa rānei, ngā wāhi kua kauhanga rānei.
I te mutunga, ko te Air Leg Rock Drill te mea tū tonu me te mea pai hoki hei whakatika mō ngā mahi tuatahi i roto i ngā taiao e hāpai ana i ngā take matihiko. Ki te āhei tōna hōtuhotu whakapai, tōna āhua whakarite, me tōna hanga e mōhio ana ki te whakamahi, ko ia te tāngata matua hei whakamahia mō ngā mahi kōpūtapu, ngā tihi whenua, ngā hanganga, me ngā kaupapa whakawehenga wai. Mō ngā tohunga e hiahia ana ki tētahi tāngata whakatakoto me te tūora, ko te Air Leg Rock Drill te whiringa pai.
