Ukumba okungcwatshiwe kanye nokuwa kwemigodi yizinkinga ezivame kakhulu nezikhathazayo kumaphrojekthi amaningi okwakhiwa kokumba ama-geological.Kunzima ukuqinisekisa ikhwalithi nokusebenza kahle kokumba ngobuchwepheshe obujwayelekile bokubhola.
Kodwa-ke, ukubonakala kwepayipi elandelayo kuyixazulula ngokuphelele le nkinga.Ivikela udonga lwe-borehole nge-casing ngenkathi ibhoboza kahle, futhi ivimbela ukugoba kwe-borehole ngomthelela oqondisayo we-casing.Njengamanje, amathuluzi okumba amapayipi aqinile futhi agxile asetshenziswa kabanzi eShayina.Ngenxa yokuqina kodonga lwebhithi yangaphandle, umthelela wokudlulisa amandla wethuluzi lokumba eligxile awumuhle njengalowo wethuluzi lokumba elingenasici lokwakhiwa kwembobo efanayo.Kuphela uma ububanzi bethuluzi lokubhoboza bukhulu futhi i- impactor enomfutho womoya ophezulu ikhethiwe, umphumela uba ngcono, kodwa izindleko zokukhiqiza ziphakeme kakhulu kunalezo zethuluzi lokumba i-eccentric.Ithuluzi lokumba ipayipi le-Eccentric aligcini nje ngokuba nobubanzi bembobo enkulu, kodwa futhi linesakhiwo esilula, izindleko eziphansi zokukhiqiza futhi kulula ukuyisebenzisa, ngakho-ke selisetshenziswe kabanzi.
Umgomo wokusebenza we-eccentric bit uthi:
1, i-DTH hammer eccentric enesistimu yokumba amapayipi, noma ngabe i-eccentric enamathuluzi okumba amapayipi aneshubhu lapho ukubhoboza okubhobozwe nge-eccentric kukhulu kunembobo yobubanzi be-casing, futhi lapho kubholwa emhlabathini onqunywe kusengaphambili, ukuhlangana, namathuluzi okumba amapayipi. ingenziwa nge-diameter yangaphandle enkulu kunazo zonke yethuluzi lokumba ipayipi elingaphansi kobubanzi bangaphakathi bamabhuzu e-tube, i-casing, ukususa ngamathuluzi okumba amapayipi, i-casing ingase ihlale ekubunjweni evikela udonga lwembobo.
2. Uma ubhoboza ngokujwayelekile, umoya ocindezelwe ohlinzekwa yi-compressor yomoya ungena ku-DTH impactor ngokusebenzisa i-drill kanye nepayipi yokubhoboza ukuze isebenze.I-piston ye- impactor ithinta i-normalizer yethuluzi lokumba ngeshubhu, futhi i-normalizer idlulisa igagasi lokushaqisa kanye nokucindezela kwebhithi ku-eccentric bit kanye nebhithi emaphakathi ukuze kuphuke idwala ngaphansi kwembobo.
3. Uma amandla adonsela phansi e-casing makhulu kunokumelana nokungqubuzana kokubunjwa odongeni lwe-casing, i-casing izolandela ngesisindo sayo.
4. Imbobo ebhojwe yi-eccentric bit inkulu kunobukhulu obungaphandle be-diameter ye-casing, ukuze i-casing ingavinjelwa idwala elingaphansi kwembobo futhi ilandele phezulu.
