Umgomo wokusebenza we-rig yokumba ejikelezayo

Imishini yokubhoboza ejikelezayo ebuyela emuvaiyithuluzi lokubhoboza elijikelezayo. Lifanele ukwakhiwa kwezakhiwo ezahlukahlukene eziyinkimbinkimbi njengesihlabathi esisheshayo, udaka, ubumba, itshe elincane, ungqimba lwamatshe, idwala eligugile, njll., futhi lisetshenziswa kabanzi ekwakhiweni kwezakhiwo, amabhuloho, ukugcinwa kwamanzi, imithombo, ugesi, ezokuxhumana, ukuna kwemvula kobunjiniyela kanye neminye imisebenzi.

Isimiso sokusebenzaumshini wokubhoboza ukujikeleza okuphambene:

I-rig yokubhoboza ebizwa ngokuthi i-reverse circulation isho ukuthi uma isebenza, i-rotary disc izoshayela i-drill bit ukuze isike futhi iphule idwala nomhlabathi emgodini, uketshezi lokubhoboza luzogeleza luye phansi emgodini lusuka endaweni evulekile phakathi kwepayipi lokubhoboza nodonga lwembobo, lupholise i-drill bit, luthwale i-slag yokubhoboza idwala nomhlabathi esikiwe, bese lubuyela emhlabathini lusuka emgodini wepayipi lokubhoboza. Ngesikhathi esifanayo, uketshezi lokubhoboza luzobuyela emgodini ukuze lwakhe umjikelezo. Njengoba ububanzi bomgodi wangaphakathi wepayipi lokubhoboza buncane kakhulu kunobomgoqo ovulekile, amanzi odaka epayipini lokubhoboza akhuphuka ngokushesha kakhulu kunokujikeleza okuvamile. Akuwona amanzi ahlanzekile kuphela, kodwa futhi angaletha i-slag yokubhoboza phezulu kwepayipi lokubhoboza bese egeleza ethangini lokudaka, lapho udaka lungaphinde lusetshenziswe khona ngemva kokuhlanzwa.

Umgomo uwukufaka ipayipi lokubhoboza emgodini ogcwele uketshezi lokugeza, kanye nokujikeleza kwetafula elijikelezayo, shayela induku yokudlulisa umoya eqinile kanye ne-drill bit ukuze ujikeleze futhi usike idwala nomhlabathi. Umoya ocindezelwe ufafazwa usuka embotsheni ekugcineni okungezansi kwepayipi lokubhoboza, kwakha ingxube yodaka, isihlabathi, amanzi kanye negesi elula kunamanzi epayipini lokubhoboza lapho inhlabathi nesihlabathi zisikwa. Ngenxa yomphumela ohlangene womehluko wokucindezela phakathi kwangaphakathi nangaphandle kwepayipi lokubhoboza kanye nomfutho wokucindezela komoya, ingxube yegesi yamanzi esihlabathi sodaka izokhuphuka kanye noketshezi lokugeza, futhi izokhishwa echibini lodaka lomhlabathi noma ethangini lokugcina amanzi ngepayipi lokucindezela. Inhlabathi, isihlabathi, amatshe ayigugu kanye nemfucumfucu yamadwala izohlala echibini lodaka, futhi uketshezi lokugeza luzogeleza emgodini womsele futhi.

Izici zeumshini wokubhoboza ojikelezayo obuyela emuva:

1. I-drill yokujikeleza okujikelezayo ifakwe ingalo yomshini enepayipi lokubhoboza, engasetshenziswa ezimweni zembobo eqondile kanye ne-angle encane ye-vertex. Ngesikhathi esifanayo, i-rig yokubhoboza ifakwe ne-winch ye-hydraulic eyisizayo, enciphisa kakhulu amandla okusebenza kwabasebenzi bomshini, futhi ivumela ukwakhiwa komshini okuphephile nokuphucuzekile.

2. I-rig yokubhoboza isebenzisa i-crawler yobunjiniyela kanye ne-hydraulic walking chassis, okulula ukuyihambisa futhi ifaneleka kakhulu emathafeni, emathafeni, emagqumeni nakwezinye izindawo. I-chassis ifakwe ama-outriggers amane, ngakho-ke i-rig yokubhoboza inokudlidliza okuphansi kanye nokuqina okuhle ngesikhathi sokwakhiwa kokubhoboza.

3. I-rig yokubhoboza ejikelezayo iqhutshwa amandla kagesi, ngomsindo ophansi kanye nokungcola, ukusebenza kahle okuphezulu kanye ne-coefficient enkulu yokugcina amandla.

4. I-reverse circulation drilling rig inemisebenzi eminingi, futhi zonke izingxenye ezibalulekile ziyimikhiqizo engabizi kakhulu. Uhlelo luhlonyiswe ngezivikelo zokucindezela kanye namadivayisi e-alamu.

5. Izibambo namathuluzi azo zonke iziqalisi ze-reverse circulation drilling rig zitholakala epulatifomu yokusebenza, elula futhi ethembekile ekusebenzeni nasekulawuleni.

6. I-reverse circulation drilling rig isebenzisa uhlaka lokubhoboza oluhlukile. Inqubo yokubhoboza inkulu, ukumelana nokugoba kukhulu, isakhiwo silula, ukulungiswa kulula, ukufuduka kulula, ukusebenza kwe-orifice kulula, futhi ukubhoboza kwe-vertex angle enkulu kungakhiwa.

7. I-rig yokubhoboza i-reverse circulation isebenzisa ikhanda elikhulu lamandla elinomsebenzi wokumelana nokushayisana okukhulu. Ijubane lokujikeleza lifanele izidingo zokujikeleza kwe-reverse air. Amandla okuphakamisa, i-torque kanye neminye imingcele ingahlangabezana nezidingo zokujikeleza kwe-DTH kwe-100M shallow air reverse circulation kanye nezinye izidingo zenqubo.
