Izinhlobo Ezintathu Zokubhoboza Idwala

Kunezindlela ezintathu zokumba amatshe - ukubhola ngokujikeleza, i-DTH (phansi kwembobo) kanye nokubhola kwesando esiphezulu. Lezi zindlela ezintathu zifanele imisebenzi ehlukene yezimayini kanye nokumba imithombo, futhi ukukhetha okungalungile kuzodala ukulahlekelwa okukhulu.

Okokuqala, kufanele sazi izimiso zokusebenza kwazo.

Ukubhola okujikelezayo

Ekubholeni okujikelezayo, i-rig inikeza ukucindezela kwe-shaft eyanele kanye ne-torque ejikelezayo. I-bit drills futhi ijikeleze edwaleni ngesikhathi esifanayo, esebenzisa kokubili ukucindezela komthelela omile nokuguquguqukayo edwaleni. Amabhithi ajikelezayo futhi agaye ngokuqhubekayo phansi kwembobo ukuze enze idwala liqhekeke. Umoya ocindezelwe ngaphansi kwengcindezi ethile kanye nezinga lokugeleza lifuthwa kusuka kubhobho ngokusebenzisa ingaphakathi lepayipi lokubhoboza, ukwenza i-slag iqhume ngokuqhubekayo ukusuka phansi kwembobo eduze kwesikhala se-annular phakathi kwepayipi lokubhoboza kanye nodonga lonke ukuya ngaphandle.

Ukubhola phansi kwembobo (DTH).

Ukubhoboza phansi ngembobo ukushayela isando esingemuva kwe-drill bit ngomoya ocindezelwe ngepayipi lokubhoboza. I-piston ishaya kancane kancane, kuyilapho isilinda sangaphandle esando sinikeza isiqondiso esiqondile nesizinzile se-drill bit. Lokhu kwenza umthelela wamandla ungalahleki emalungeni futhi uvumele ukubhobozwa kwe-percussion okujule kakhulu.

Ngaphezu kwalokho, amandla okuthinta asebenza edwaleni elingaphansi kwembobo, elisebenza kahle kakhulu, futhi liqondile kunezinye izindlela zokusebenza kokumba.

Futhi i-DTH ifaneleka kakhulu imbobo enkulu yokumba amatshe aqinile, okukhethekile ngokuqina kwamadwala okungaphezu kuka-200Mpa. Kodwa-ke, edwaleni elingaphansi kwama-MPa angama-200, ngeke nje kumoshe amandla, kodwa futhi nasekusebenzeni okuphansi kokumba, kanye nokuguga okungathí sina ku-drill bit. Kungenxa yokuthi ngenkathi i-piston yesando ishaya, idwala elithambile alikwazi ukumunca umthelela ngokuphelele, okwehlisa kakhulu ukusebenza kahle kokubhola nokugwaza.

Top Hammer Drilling

Amandla okushaya amanzi okubhoboza isando esiphezulu akhiqizwa ipiston yepompo kumshini wokumba we-hydraulic, adluliselwa ku-drill bit nge-adaptha ye-shank kanye nepayipi lokubhoboza.

Lona umehluko phakathi kokubhola kwe-DTH. Ngaleso sikhathi, isistimu ye-percussion ishayela ukujikeleza kwesistimu yokumba. Lapho igagasi lokucindezeleka lifika ku-drill bit, amandla adluliselwa edwaleni ngendlela yokungena kancane. Inhlanganisela yale misebenzi ivumela ukubhoboza izimbobo edwaleni eliqinile, futhi i-compressor yomoya yenza kuphela ukususa uthuli kanye nokugqwala ekubhobozeni isando esiphezulu.

Amandla omthelela aphindaphindeka ngokuvama komthelela ndawonye adala ukuphuma kwe-percussive ye-drifter. Kodwa-ke, imvamisa, ukubhoboza kwesando esiphezulu kusetshenziselwa ubukhulu bembobo obungu-127mm, nokujula kwembobo kungaphansi kuka-20M, okusebenza kahle kakhulu.
