1.Imbobo yokuphambuka ebukhali ngokuvamile ibangelwa yi-geology. Ngenxa yezinga lokuwohloka kwengqimba yamadwala, ukusatshalaliswa kwamadwala okungalingani, njll., ipayipi lokubhoboza liyabhajwa ngokuzumayo lapho umqulu oyinhloko ufika endaweni ethile emgodini, noma ipayipi lokubhoboza ligoba ngokuzumayo ohlangothini olulodwa, okubonisa ukuphambuka ngokuzumayo endaweni ethile emgodini.
2 Ukuphambuka kancane Ngokwandiswa komqulu oyinhloko kanye nokujula komgodi, ingxenye yokuqala yepayipi lokubhoboza iya phambili iye emgqonyeni bese iphambuka phakathi nendawo, kanti ingxenye yokuqala yepayipi lokubhoboza ihlala isondela emgqonyeni ohlangothini olulodwa, okubonisa ukuthi umgodi uphambuka kancane ohlangothini olulodwa, futhi lapho umgodi usondela khona uthambekele eceleni.
3 Ukuphambuka okungajwayelekile ngepayipi lokubhoboza phansi, ipayipi lokuqala lokubhoboza linyakaza kusukela kolunye uhlangothi kuya kolunye, noma emgodini owomile wokubhoboza kungabuka ngqo emgodini ngaphandle kokuphambuka okuvamile okujikelezayo, lesi simo sokuphambuka ikakhulukazi sibangelwa ungqimba lwedwala olugcwele noluqinile, ngenxa yamandla angalingani okubhoboza ipayipi lokubhoboza ukuphambuka okude.1. I-geological geology iyisizathu esiyinhloko sembobo engaphelele. Uma i-geology ingungqimba olungenalutho kanye nongqimba wobumba, ngeke kube khona ukuphambuka emgodini. Iningi lazo libangelwa izinguquko ze-geological kanye nokusatshalaliswa okungalingani kwedwala eligugile kanye nedwala, okuholela emandleni angalingani ebhakede lokubhoboza ngesikhathi sokubhoboza.2 Umsebenzi oyinhloko webhakede lokubhoboza ukusika ukubhoboza, kodwa futhi unomsebenzi wokuqondisa nokuvimbela ukuphambuka. Iphuzu lomshayeli wesikhungo sokubhoboza linomsebenzi wokubeka indawo, futhi iphuzu lomshayeli lingashintsha ukuhleleka kokubhoboza, inani kanye ne-engeli yamazinyo okubhoboza Noma ngabe izinga lihambisana, noma ngabe ukuphakama kommese ohlangothini noma umugqa ovikelayo ezinhlangothini zombili zomzimba wokubhoboza kuyafana, le mininingwane ingenza ukubhoboza ibhakede lokubhoboza kwesobunxele nakwesokudla kuphoqe ukuthi kufane futhi kuvimbele ukuphambuka.3 Ukusebenza Uma kukhona amatshe, amatshe okukhukhuleka, amatshe amatshe, izingqimba zamatshe ezigugile emgodini, kuyadingeka ukulawula imodi yokuntanta kanye nengcindezi, uma ukubhoboza okusheshayo kuzobangela imbobo yokuphambuka ebukhali.
Indlela yokuvimbela imbobo engaphelele 1 ukuqonda ubunjiniyela bokuphenya nge-geological ngokusebenzisa umbiko we-geological, isampula eyinhloko, indawo ezungezile njalo njalo, ukuqonda okuningiliziwe ngesimo se-geological.2 Ngokuqinisekisa kwangempela, ibhakede lika-roger lingavimbela ukuphambuka okungcono kunebhakede lesihlabathi elingaphansi eliphindwe kabili, ngoba ukumelana kokubhoboza kwebhakede lika-roger ger kuncane, okungavimbela ngempumelelo imbobo yokuphambuka endleleni yokubhoboza yomshayeli.3 Lungiselela ibhakede lokubhoboza ngangokunokwenzeka, ukuze ibhakede lokubhoboza linciphise ukumelana kokubhoboza, ikakhulukazi ithiphu eliphakathi lomshayeli linomphumela wokuma, ongavimbela ngempumelelo imbobo yokuphambuka.4 Ipayipi lokubhoboza eliqondisayo lingashisela isilinda sokuvikela esingamamitha ama-2 ubude esivumelana nobubanzi bokuvuleka ngaphezu kwepayipi lesikulufu noma ipayipi lokubhoboza elingaphansi eliphindwe kabili. Ngokwandisa ukubhoboza okuqondisayo kwepayipi lokubhoboza, le ndlela ingavimbela ngempumelelo imbobo yokuphambuka.5 Ukulawula ukusebenza okuntantayo, ingcindezi, isivinini kanye nesivinini sokubhoboza sokulawula kunganciphisa ngempumelelo ukuphambuka.6 Indlela yokubhoboza ihlulela isimo samanje se-geological ngokudlidliza nomthwalo, futhi ishintsha indlela yokubhoboza: njengokusika ukubhoboza, ukuchoboza ukubhoboza, ukuhambisa ukubhoboza kanye nokubhoboza ukugaya, kanye nokushintsha indlela yokubhoboza nakho kungavimbela ngempumelelo imbobo yokubhoboza engaphelele.
Indlela yokulungisa i-A, imbobo egobile ayinzima, ingalungisa i-rig ukuze iqhubeke nokubhoboza. Ezimweni ezimbi kakhulu, ubumba kufanele lugcwaliswe emuva bese lubhobozwa ngemva kokufakwa okuxinene. Ungasebenzisi i-impact drill ukulungisa imbobo ngqo ukuze ugweme ukubhoboza. B. Uma ukuphambuka kungekubi kakhulu futhi ubulukhuni bomphezulu wedwala bungaphakeme, sebenzisa i-flat bottom drill bit ukuze ulinganise bese ubhoboza noma usebenzise i-drill bit encane ngaphambi kokubhoboza. C. Uma ukuphambuka kukubi kakhulu futhi ubulukhuni bomphezulu wedwala buphakeme, inqwaba yokubhoboza isezingeni elifanayo lekhonkrithi ngokushesha. Lapho amandla ekhonkrithi efinyelela ngaphezu kuka-70%, imbobo encane yokubhoboza izonwetshwa; D. Uma ukuphambuka kukubi kakhulu futhi inani lamanzi angaphansi komhlaba lingelikhulu, imbobo esetshenziswa ngesandla ingasetshenziswa ukulungisa umphezulu wedwala othambekele.
