I-rig yokubhoboza ejikelezayo ene-headroom ephansi uhlobo olukhethekile lwemishini yokubhoboza engasebenza ezindaweni ezinesikhala esincane sokuhamba. Ivame ukusetshenziswa ezimbonini nasezinhlelweni ezahlukahlukene, okuhlanganisa:
Ukwakhiwa Kwasemadolobheni: Ezindaweni zasemadolobheni lapho isikhala sincane khona, ama-rotary rig okubhoboza angaphansi kwekhanda asetshenziswa ukubhoboza isisekelo, ukufaka inqwaba, kanye neminye imisebenzi yokwakha. Angafakwa ezindaweni eziqinile phakathi kwezakhiwo noma ngaphakathi kwezindlu ezingaphansi komhlaba, okuvumela imisebenzi yokubhoboza ephumelelayo nenembile.
Ukwakhiwa Nokunakekelwa Kwebhuloho: Ama-rig okubhoboza ajikelezayo ane-headroom ephansi avame ukusetshenziswa kumaphrojekthi okwakha nokulungisa amabhuloho. Angasetshenziswa ukubhoboza izisekelo zezinqwaba zezinsika zamabhuloho nama-abutment, kanye nokuqinisa nokuqinisa izakhiwo zamabhuloho. Umklamo we-headroom ephansi wenza la ma-rig akwazi ukusebenza ngaphansi kwezimo zokuphuma okuvinjelwe, njengangaphansi kwamabhuloho akhona.
Ukumba Nokumba: Ama-rotary drilling rig aphansi athola ukusetshenziswa emisebenzini yokumba nokumba. Angasetshenziswa ekumba ngokuhlola ukuhlola ikhwalithi kanye nobuningi bamaminerali agciniwe, kanye nokumba imigodi yokuqhuma ukuze kube lula ukukhipha. Lawa ma-rig aklanyelwe ukusebenza ezindaweni ezivalekile, njengezimayini ezingaphansi komhlaba noma ubuso be-quarry, lapho ukususwa kwesikhala ngaphezulu kungase kuncishiswe khona.
Ukumba Imihubhe kanye Nokumba Ngaphansi Komhlaba: Emaphrojekthini okumba imihubhe kanye nokumba ngaphansi komhlaba, ama-rig okumba ajikelezayo angaphansi kwe-headroom asetshenziselwa ukumba imigodi yokuqhuma, ukufaka izinhlelo zokusekela umhlabathi, kanye nokwenza uphenyo lwe-geological. Angasebenza ezihlokweni zemihubhe, emigodini, noma emakamelweni angaphansi komhlaba ane-headroom enqunyelwe, okwenza kube lula ukumba kanye nemisebenzi yokwakha ephumelelayo.
Uphenyo Lwe-Geotechnical: Ama-rotary drilling rigs aphansi avame ukusetshenziselwa uphenyo lwe-geotechnical ukuhlola izimo zenhlabathi namadwala kumaphrojekthi wobunjiniyela nokwakha. Angafakwa ezindaweni ezinokufinyelela okulinganiselwe noma indawo evulekile ngaphezulu, njengezindawo zasemadolobheni, izintaba, noma izindawo zokwakha ezivalekile. Lawa ma-rigs avumela ukuqoqwa kwamasampula enhlabathi namadwala ukuze kuhlolwe elebhu futhi ahlinzeke ngedatha ebalulekile yokuklama isisekelo nokuhlaziywa kwenhlabathi.
Inzuzo eyinhloko yama-rotary rig aphansi asebenza kahle yikhono lawo lokusebenza ezindaweni ezinesikhala esincane esingaphezulu. Umklamo wawo omncane kanye nezici ezikhethekile ziwavumela ukuthi asebenze kahle ezindaweni ezixineneyo, okwenza kube lula ukubhoboza kanye nemisebenzi yokwakha ebingaba yinselele noma ingenzeki ngemishini ejwayelekile yokubhoboza.
