I-headroom rotary drilling rig esezingeni eliphansi iwuhlobo olukhethekile lwemishini yokumba engasebenza ezindaweni ezinomkhawulo we-overhead clearance. Isetshenziswa kakhulu ezimbonini nasezintweni ezahlukahlukene, kufaka phakathi:
Ukwakhiwa Kwamadolobha: Ezindaweni zasemadolobheni lapho isikhala sincane, izinsimbi zokugaya ezijikelezayo ezisezingeni eliphansi zisetshenziselwa ukumba isisekelo, ukunqwabelanisa, neminye imisebenzi yokwakha. Angatshalwa ezindaweni eziqinile phakathi kwezakhiwo noma ngaphakathi kwezindlu ezingaphansi, okuvumela ukusebenza kahle nokunemba kokumba.
Ukwakhiwa Nokugcinwa Kwebhuloho: Izinsimbi zokumba ezijikelezayo ezingaphansi kwe-headroom zivame ukusetshenziswa ekwakhiweni kwebhuloho nasekulungiseni amaphrojekthi. Angasetshenziswa ukubhola isisekelo senqwaba yezinsika zamabhuloho kanye nama-abutments, kanye nokumisa ihange kanye nokusimamisa izakhiwo zamabhuloho. Idizayini ye-headroom ephansi yenza lawa ma-rigs asebenze ngaphansi kwezimo ezikhawulelwe zokugunyazwa, njengangaphansi kwamabhuloho akhona.
Izimayini kanye Nokumbiwa Kwezikwali: Izinsimbi zokumba ezizungezayo ezisezingeni eliphansi zithola izinhlelo zokusebenza zezimayini nokumba izinkwali. Angasetshenziselwa ukumba okuhlola ukuhlola ikhwalithi kanye nenani lamadiphozi amaminerali, kanye nokubhoboza imigodi ukuze kube lula ukumba. Lawa ma-rigs aklanyelwe ukusebenza ezindaweni ezivalekile, njengezimayini ezingaphansi komhlaba noma ubuso benkwali, lapho ukuvunyelwa phezulu kungase kube nomkhawulo.
Ukumba Umhubhe Nokumbiwa Ngaphansi Komhlaba: Emisebenzini yokumba umhubhe kanye nokumba ngaphansi komhlaba, izinsimbi zokumba ezizungezayo ezisezingeni eliphansi zisetshenziselwa ukumba izimbobo eziqhumayo, ukufaka izinhlelo zokusekela umhlabathi, kanye nokwenza uphenyo lwe-geological. Angasebenza ezihlokweni zikamhubhe, emigodini, noma emakamelweni angaphansi ane-headroom ekhawulelwe, okuvumela ukumba okuphumelelayo nemisebenzi yokwakha.
Uphenyo Lwe-Geotechnical: Izinsimbi zokumba ezijikelezayo ze-headroom ephansi zivame ukusetshenziselwa uphenyo lwe-geotechnical ukuhlola izimo zenhlabathi namadwala onjiniyela namaphrojekthi wokwakha. Angatshalwa ezindaweni ezinomkhawulo wokufinyelela noma indawo engaphezulu, njengeziza zasemadolobheni, amathambeka, noma izindawo zokwakha ezivaliwe. Lawa ma-rigs anika amandla ukuqoqwa kwamasampula enhlabathi namadwala ukuze ahlolwe elabhorethri futhi anikeze idatha ebalulekile yokwakheka kwesisekelo nokuhlaziywa kwenhlabathi.
Inzuzo eyinhloko yama-rigs okumba ama-headroom aphansi amandla awo okusebenza ezindaweni ezinomkhawulo we-overhead clearance. Idizayini yabo ehlangene nezici ezikhethekile zibavumela ukuthi basebenze kahle ezindaweni eziqinile, okwenza imisebenzi yokumba neyokwakha engaba inselele noma engenakwenzeka ngemishini evamile yokumba.
