Ngā Kaupapa Taketake o te Arotakenga Ruāwhenua VSP
Pendahuluan
Ko te Whakatakotoranga Ruāwhenua Poutū (VSP) he tikanga ā-whenua e whakamahia ana hei tiki mōhiohio tino tika mō te mata o raro o te Ao. Ka whakamahia e tēnei tikanga ngā ngaru ruāwhenua i hangaia e ngā pūtake ruāwhenua i runga i te mata, ā, ka hopukina e ngā kaiwhiwhi (geophone) kua whakanohoia ki roto i ngā poka wai. Kua tere te whanaketanga o ngā tikanga VSP i ngā tekau tau tata nei, ā, kua waiho hei taputapu nui i roto i te tūhuratanga hinu me te hau me ngā rangahau ā-whenua. Ka whakamāramahia e tēnei tuhinga ngā mātāpono taketake, ngā momo VSP, ngā tono, me ngā painga me ngā ngoikoretanga.
Ngā Mātāpono Taketake
He rite tonu ngā mātāpono o te mahi a te VSP ki ngā rangahau ru whenua tuku iho, engari me whakanoho he kaiwhiwhi ki roto i te poka. Kei roto i tēnei rangahau te kimi i ngā ngaru ru whenua e whakaatahia ana, e hurihia ana hoki e ngā paparanga whenua o raro i te mata. Ko te painga matua o te whakanoho i te kaiwhiwhi ki roto i te poka ko te whakapai ake i te taumira me te kounga raraunga huri noa i te poka, nā te mea me haere ngā ngaru ru whenua mā roto i ngā paparanga oneone iti ake i ngā rangahau mata.
Pūtake me te Kaiwhiwhi Rū
– Pūtake Rūwhenua: Ko te tikanga ka whakatakotoria he pūtake ngaru rūwhenua ki runga i te mata e tata ana ki te poka. Ko te whakamahi i tētahi pūtake kaha, arotahi te mea nui ki te whakanui ake i te urunga me te kounga o ngā raraunga.
– Ngā Kaiwhiwhi (Geophones): Ka whakanohoia ngā kaiwhiwhi ki ngā hōhonutanga motuhake i roto i te poka, ā, kua hangaia hei kite i ngā wiri rū whenua me te tino tika. Ka taea te tāuta i ēnei i ngā wā rerekē i runga i ngā whāinga rangahau.
Whirihoranga me te Kohi Raraunga
Ka kohia ngā raraunga VSP mā te whakanoho i ngā geophone ki ngā hohonutanga rerekē i roto i tētahi poka wai, me te tuhi i te wā haere o ngā ngaru ru mai i te pūtake, mā roto i ngā paparanga whenua, ki te kaiwhiwhi. I te nuinga o te wā, ka whakahokia tēnei mahi kia maha ngā wā hei tiki raraunga i ngā hohonutanga geophone rerekē, kātahi ka whakamahia hei hanga i tētahi kōtaha poutū o te mata o raro o te Ao.
Ngā momo VSP
He maha ngā momo rangahau VSP, he rerekē ngā whakamahinga me ngā painga o ia momo. Anei ētahi o ngā momo matua:
VSP Kore-Whakataurite
Ko te VSP kore-whakawhiti te momo taketake o te VSP, arā, ko te pūtake rū whenua kei runga tonu i te poka. Mā tēnei tikanga ka whakaratohia he mōhiohio pai mō te hanganga whenua kei raro tonu i te poka. Kei roto i ngā raraunga i whiwhihia ko ngā wā haere o ngā ngaru tuatahi, ngā ngaru maha, me ngā whakaata mai i ngā paparanga whenua rerekē.
VSP Whakakore
I roto i te VSP rerekē, ka whakatakotoria te pūtake rū whenua ki tētahi tawhiti whakapae mai i te poka wai. Mā tēnei tikanga ka taea te whakaahua i ngā hanganga whenua i tawhiti atu i te poka wai. He tino whai hua te VSP rerekē mō te tautuhi me te mahere i ngā āhuatanga whenua pēnei i ngā hapa me ngā kopikopiko kāore e taea te kite me te VSP kore-whakawhiti.
Walkaway VSP
I roto i te rangahau VSP hikoi, ka nekehia te pūtake ru whenua i runga i te āhua rārangi i runga i te mata o te whenua, ko te poka wai hei pūwāhi pumau mō te kaiwhiwhi. Ka whakamahia tēnei tikanga hei tiki i tētahi whakaahua rua-ahu o te hanganga whenua e karapoti ana i te poka wai. He tikanga whai hua te VSP hikoi mō te whakatauira whenua uaua me te manatoko i ngā raraunga ru whenua o te mata.
VSP 3D
He whanaketanga matatau te 3D VSP, e whakaritea ana te pūtake me te kaiwhiwhi ki tētahi whirihoranga toru-ahu. Mā tēnei tikanga ka whakaratohia he mōhiohio tino taipitopito, ā, ka taea te whakaahua i ngā hanganga whenua e karapoti ana i te poka. Ka whakamahia ngā raraunga 3D VSP hei arotau i ngā wāhi hou o te poka, hei whakawhānui ake hoki i te tūhuratanga o te mara.
Whakatinanatanga VSP
He whānuitia ngā whakamahinga o te tikanga VSP i roto i te umanga hinu me te hau, me ngā rangahau whenua hoki. Ko ētahi o ngā whakamahinga matua ko:
Te Tūhuratanga Hinu me te Hau
1. Te Āhuatanga o te Puna Wai: Ka whakamahia te VSP mō te āhua o te puna wai mā te whakarato i te whakaahua mārama o ngā rohe o te puna wai me te rerekētanga i roto i te puna wai.
2. Te Whakatakotoranga me te Keri i te Puna: Mā ngā mōhiohio e whiwhi mai i ngā rangahau a te VSP ka āwhina i te whakatakotoranga tika o te puna, ā, ka karohia hoki ngā rohe mōrearea ka whakararuraru pea i ngā mahi keri.
3. Aroturukitanga Wā-Wā: Ka whakamahia ngā rangahau VSP auau (4D VSP) hei aroturuki i ngā huringa i roto i te puna wai i te wā whakaputa, ā, mā tēnei ka āwhina i ngā whakataunga whakahaere puna wai me te whakamahere weronga tuarua.
Ngā Hangarau Whenua me ngā Tūponotanga Whenua
1. Rangahau Pūmautanga o te pari: Ka whakamahia te VSP hei aromatawai i ngā hanganga o raro i te mata, me te tautuhi i ngā rohe ngoikore ka raru ai te pumau o te pari.
2. Ngā Tūāpapa me te Hanganga: Mā ngā rangahau VSP ka āwhina i te aromatawai i ngā āhuatanga o raro i te whenua mō te hoahoa i ngā tūāpapa whare me ngā hanganga nui, kia tika ai te tautoko me te pumau.
3. Aromatawai Mōrearea Rūwhenua: Mā te kimi me te mahere i ngā hapa hohe i raro i te whenua, ka taea te whakamahi i te VSP hei aromatawai i ngā mōrearea rūwhenua mō ngā whanaketanga i ngā wāhi e pāngia ana e te rūwhenua.
Te Rangahau Pūtaiao
Haunga ngā mahi ahumahi, ka whakamahia hoki te VSP i roto i ngā rangahau pūtaiao hei mārama ki te hanganga me ngā hihiri o te Ao. Ko te rangahau mō te ru whenua me te puia he maha ngā wā ka whakamahia ngā raraunga VSP hei tautuhi i ngā tukanga e puta ana i raro i te mata o te Ao, me te whakawhanake i ngā tauira matawhenua tika ake.
Ngā Painga me ngā Here
Putanga:
1. Taumira Teitei: Mā te whakanoho i ngā geophone ki roto i te poka ka puta he raraunga taumira poutū teitei, he mea nui tēnei mō te tātari taipitopito.
2. Kounga Tohu Pai Ake: He iti ake te haruru o ngā rekoata ngaru rū i roto i ngā poka i ērā o te mata.
3. Ngā Mōhiohio Tika mō te Papa o raro: Ka whakarato a VSP i ngā mōhiotanga tika mō te hanganga me ngā āhuatanga ā-tinana o ngā paparanga whenua i raro i te poka, he mea nui tēnei mō ngā whakataunga tika mō te tūhura me te whakamahi.
Te Whakatakotoranga:
1. Te utu: He nui te utu mō ngā ruri VSP nā te mea e hiahiatia ana he taputapu motuhake me ngā mahi keri, ā, i ētahi wā he tino utu nui.
2. He iti te kapinga: Ko te nuinga o ngā raraunga VSP he iti noa iho ki te rohe e karapoti ana i te poka, ā, kāore pea e kapi i tētahi rohe nui ina whakaritea ki ngā rangahau rū whenua.
3. Ngā Uauatanga Whakahaere: Ko te whakahaere i ngā taputapu matawhenua i roto i ngā poka keri me whai pūkenga motuhake, ā, he uaua pea, inā koa i roto i ngā taiao uaua o raro whenua.
Whakamutunga
He tikanga rangahau whenua te VSP, he tino whai hua i roto i ngā momo mara, tae atu ki te tūhuratanga hinu me te hau me ngā rangahau whenua. Mā te whakarato i ngā raraunga kounga teitei, he uaua ki te tiki mā ngā tikanga tuku iho, ka tukuna e te VSP he tirohanga hōhonu ki te hanganga me ngā āhuatanga whenua o raro i te whenua. Ahakoa he iti noa ōna herenga, ko ngā painga o tēnei tikanga he mea nui mō ngā kaupapa tūhuratanga me te rangahau.
