Nakuba kungezona amathuluzi asensimini, lezi zinsimbi ziyingxenye ebalulekile "yeketanga lokulinganisa" lokuhlola futhi kumele zisekelwe yizinqubo ze-QA/QC (Quality Assurance/Quality Control) njengokusetshenziswa kwezinto ezingenalutho, amakhophi aphindaphindiwe, kanye nezinto zokubhekisela ezijwayelekile.
Amathuluzi Okulinganisa I-Geophysical Ekuhloleni
I-Geophysics isisiza "ukubona" indawo engaphansi komhlaba ngaphandle kokumba. Ngakho-ke, izinsimbi zokulinganisa i-geophysical zibalulekile.
1. I-Magnetometer
Ama-magnetometer alinganisa ukwehluka kwensimu yamagnetic yoMhlaba, okuthonywa izinhlobo zamadwala kanye nokuqukethwe kwamaminerali athile (isb., i-magnetite). Ukuhlolwa kwamagnetic kuvame ukusetshenziselwa ukumaka izakhiwo zesifunda, ukungena, kanye nezindawo zokuguqulwa okungenzeka kuhlotshaniswe nokwakheka kwamaminerali.
2. Imitha Yokumelana Nokuqhekeka Okubangelwa (i-IP)
Izindlela zokumelana ne-IP zilinganisa impendulo kagesi yamatshe. Izindawo ezinamatshe amaminerali e-sulfide zivame ukubonisa ukungalingani kwe-IP (ukushaja). Ukulinganisa kwenziwa kusetshenziswa ama-electrode afakwe ebangeni elithile ukusuka ebusweni, ngakho-ke ukunemba kwebanga, isikhundla, kanye nokuphakama kwamaphuzu okulinganisa kuthinta kakhulu ikhwalithi yokuhumusha.
3. I-Radar Engena Emhlabathini (GPR) kanye ne-Seismic
I-GPR isetshenziswa ekujuleni okungajulile, isibonelo, ukudweba izingqimba noma imigodi yenhlabathi. Izindlela zokuzamazama komhlaba (ukuzindla/ukuhlehla) ziyinkimbinkimbi kakhulu futhi zinganikeza umbono ojulile wezakhiwo ezingaphansi komhlaba. Zombili zidinga inzwa enembile kakhulu kanye nokubekwa komthombo kanye nesikhathi esinembile.
Amathuluzi Okulinganisa Ekubholeni Nasekugawuleni Imithi
Njengoba ukuhlola kungena esigabeni sokubhoboza, amathuluzi okulinganisa asetshenziswayo aya ngokuya ecacile:
1. Ithuluzi lokuhlola i-inclinometer kanye ne-downhole ukuze kulinganiswe ukuphambuka kwemigodi (i-azimuth kanye ne-dip). Ngaphandle kwalokhu, indawo yesampula eyinhloko ngaphansi kobuso ingaphambuka endaweni eqondiwe.
2. Ibhokisi eliyinhloko kanye nethuluzi lokulinganisa ukubuyisa ingqikithi ukuze kuqoshwe ubude bengqikithi etholiwe, ukubuyisa iphesenti, kanye ne-RQD (Ukuqokwa Kwekhwalithi Yedwala).
3. Amathuluzi okulinganisa ubuningi kanye nomswakama (kuye ngokuthi impahla ithengiswa kanjani) ukusekela ukubalwa kwezinsizakusebenza.
4. Isofthiwe yokurekhoda exhunywe kusizindalwazi iqinisekisa ukuthi idatha ye-lithology, ukuguqulwa, isakhiwo kanye nebanga igcinwa kahle futhi ingalandelelwa.
Ukulinganisa, i-QA/QC, kanye nokuphepha
Ukunemba kwezinsimbi zokulinganisa akuxhomekile nje kuphela kubuchwepheshe kodwa futhi nasezinqubweni. Ukulinganiswa okuvamile kuyadingeka eziteshini eziphelele, ama-base-rover e-GNSS, ama-pXRF, kanye nezinsimbi ze-geophysical. Idatha enhle yokuhlola kumele ihlolwe—okusho ukuthi kusobala ukuthi ubani olinganise idatha, nini, ngamishini mini, nokuthi kanjani.
Ukuphepha kuhlobene nezinsimbi zokulinganisa. Isibonelo, ukusetshenziswa kwama-drone kumele kulandele izinqubo zokundiza eziphephile, ukuhlolwa kwe-geophysical kumele kunake izintambo kanye nemisinga kagesi, kanti ukulinganisa ezindaweni eziphakeme kudinga imishini yokuzivikela yomuntu siqu kanye namasu okusebenza aphephile. Ukulinganisa okusheshayo noma okungajwayelekile kungabeka abasebenzi engozini futhi kubeke engcupheni ikhwalithi yedatha.
I-Penutup
Ukusetshenziswa kwezinsimbi zokulinganisa emisebenzini yokuhlola izimayini kubalulekile ekukhiqizeni idatha enembile, ehambisanayo, nethembekile. Kusukela ku-GNSS, iziteshi eziphelele, izindawo zokudlula emanzini, ama-drones, amakhampasi okwakheka komhlaba, kuya kumathuluzi okwakheka komhlaba kanye nezinsimbi zokuloba izimbobo zokubhoboza—konke kuyahambisana ekwakheni ukuqonda okuphelele kwezimo zokwakheka komhlaba kanye namandla amaminerali. Ngokulinganiswa okunembile, ukuhlola kungaba ngcono, izindleko zilawuleka kalula, izingozi ziyancishiswa, futhi izinqumo zokutshalwa kwezimali ziqine kakhulu. Ekugcineni, ikhwalithi yokuhlola inqunywa ikhwalithi yedatha, futhi ikhwalithi yedatha iqala ngokulinganisa okufanele.
