Isixhobo sokugrumba ezantsi-umngxuma, okwakwaziwa njengesixhobo sokugrumba ezantsi, luhlobo lwezixhobo zokomba ezisetyenziswa kwimigodi, ulwakhiwo, kunye namashishini okuhlola i-petroleum.Ezi zixhobo ziyilelwe ukugrumba imingxuma emhlabeni ngokusebenzisa isixhobo esifana nehamile ukuqhekeza amatye okanye umhlaba.Kukho iintlobo ezininzi zeerigi zokugrumba ezantsi kwimarike, nganye ineempawu zayo ezizodwa kunye nobuchule.Apha ngezantsi kukho iindidi eziqhelekileyo zokutsala umngxuma phantsi.
1. Umrhubhe wokugrumba ezantsi kumngxuma:
Olu hlobo lomngxunya wokugrumba ezantsi lufakwe kwi-crawler chassis kwaye inokushukunyiswa lula kumhlaba ombhoxo.Idla ngokusetyenziswa kwiiprojekthi zemigodi kunye nezokwakha apho imali yokuhlawula amatyala ibalulekile.I-Crawler down-the-hole drilling rigs iyaziwa ngokuzinza, ukuqina kunye nokusebenza kakuhle kokomba.
2. Isixhobo sokugrumba i-DTH esixhonywe kwisithuthi:
Njengoko igama libonisa, olu hlobo lwe-drilling rig ephantsi-umngxuma ifakwe kwilori ukuze ihambe ngokulula ukusuka kwenye indawo ukuya kwenye.Ngokuqhelekileyo isetyenziselwa kwiiprojekthi zokwakha iindlela kunye nezinye izicelo ezifuna ukuhamba.Izixhobo zokomba ze-DTH ezifakwe ngelori ziyaziwa ngokuguquguquka kwazo kunye nokukwazi ukugrumba imingxuma kwiintlobo ezahlukeneyo zomhlaba kunye nokwakheka kwamatye.
3. Uhlobo lwetreyila yokomba iDTH:
Ngokufana nezixhobo zokugaya i-DTH ezixhonywe kwisithuthi, i-trailer-mounted DTH drilling rigs ifakwe kwii-trailers zokuthutha lula.Iqhele ukusetyenziswa kwiiprojekthi zokwakha ezincinci kunye nokugrumba amaqula amanzi.I-trailer-enyuswe ezantsi emngxunyeni izixhobo zokomba ziyaziwa ngobungakanani bazo obubambene kunye nokusebenza ngokulula.
4. Isixhobo sokomba esingatyibilikiyo phantsi komngxuma:
I-skid-mounted DTH drilling rigs ifakwe kwiibhloko ze-skid ukunika uzinzo ngexesha lokomba.Ihlala isetyenziswa kwi-geotechnical drilling kunye neeprojekthi zokomba zokusingqongileyo.I-skid-mounted DTH rigs drilling rigs ziyaziwa ngoyilo lwazo oludibeneyo, ukufakwa lula kunye nokuchaneka okuphezulu kokomba.
5. Isixhobo sokomba sangaphantsi kwe-DTH:
Olu hlobo lwesixhobo sokugrumba i-down-the-hole yenzelwe ngokukodwa imisebenzi yokwemba phantsi komhlaba.Ngokuqhelekileyo isetyenziswe kwimigodi kunye nobunjineli be-tunnel, apho ukubhola kuyadingeka kwiindawo ezivaliweyo.Izixhobo zokuqhuba i-DTH ezingaphantsi komhlaba ziyaziwa ngobungakanani bazo obubambeneyo, ukunyathela kunye nokusebenza kakuhle ekwembeni phantsi kweemeko ezinzima.
Ngamafutshane, kukho iindidi ezahlukahlukeneyo zokugrumba imingxunya kwimarike, nganye eyenzelwe izicelo ezithile kunye neemfuno.Ingaba imigodi, ukwakhiwa okanye ukuhlola i-oyile, ukukhetha uhlobo olufanelekileyo lwe-drilling rig ephantsi-kumngxuma kubalulekile ukuqinisekisa ukusebenza ngokufanelekileyo kunye nempumelelo yokugaya.
