Ukucindezelwa Kwegcindezo: Iziphumatha Ezikhethekileyo Zokuthuthwa Kwemipu Yokudrill

Inqamu yempahla enqamulekile, ukulahlekelwa kwezinsimbi eziningi, nokucindezelwa kwematrix njengamaqoshiso aphawuliweyo

Xa usebenza ngesiliva, kukhona iminyaka yokuqala eyathululwa ukuthi sivela ngexesha lokutshintsha igolide ye-diamond: xa isiliva sesikhungo sibonakala, xa izigaba sibonisa ukugcina okukhulu, kanye xa ukucwaliswa kwe-matrix kuphazanyiswa kakhulu. Uma isikhungo siqala sokubonakala khona, lokhu kusho ukuthi izigaba ze-diamond zazigcinwa phantsi koko okuyisidingo esiphilayo. Ubunzima besithuthi buhlala buphazanyiswa, kwaye kukhona inkinga enkulu yokuba igolide iphazanyiswa ngexesha lenzeke. Izigaba ezibonakala ezimbulu, ezicacileyo, okanye eziphambene ngokwengeziyo ezakhiweni azikwazi ukugcina ngcono futhi kumelwe abe nobubi bomthwalo wemfuyo. Okuqondileyo ngomsebenzi we-matrix uphazanyiswa kuyinto ejulile—umetali owaphatha amadimanthe kuqala ukuphazanyiswa. Uma kufika ekuphazanyiseni kakhulu, amadimanthe aqala ukuhluka kakhulu kwaye wonke umfanekiso wokudweba kuphazanyiswa. Ngokwamabhaso ethuvelisiwe, ngaphezu kuka-78% yezinkinga ezifika ngokushesha zisuswe kuba le minyaka ayaziwa. Ngakho ke ukulunga kanye kuyinto eyahlukileyo ekunikela ukuphazanyiswa okuthintela imali kumasebe.

Amatheshholdi okulinganiswa: Xa kusuke kakhulu kune-30% kube yinkimbini yomfanekiso noma kusuke kakhulu kune-1.5 mm indawo yokumusha kumele ususe umshini wokugaya

Izikhala zokulinganisa zinika izimpendulo eziphatha ngokwazo ukuchaza ukuthi kufuneka ususe iphethini. Ususe iphethini uma:

• Ukuphazanyiswa kwesilinganiso kusuke kakhulu kune-30% kwezilinganiso ekuqaleni
• Ukuphazanyiswa kwematrix kusuke kakhulu kune-1.5 mm ubude
• Ukungahambelani komgwa uyaphazanyisa izivumelwano zamakhi amakhishini

Lale theshholdi zihlobana no-40% ukuphazanyiswa kokukhula kokuqeda nokuthutha kakhulu kakhulu kune-200%. Ngaphezu kwalokho, isimo sokuhlukanuka sakhulisa ngendlela ephindaphindwayo—kudingeka kakhulu emanzini amakhulu njenge-granite ne-quartzite—kuyakha ukusetshenziswa kakhona kungcono. Ukulandela lolu limithi kumenza ungahlali mhlawumbe, ungavulindleli izixhumanisi, futhi ungacindezele umsebenzisi.

Ukulahlekelwa Kokusebenza Kokuqeda: Izinyo Evulekayo Zokushintsha Umshini Wokugaya

Ukubambezela nokumelana ngokwesitshalo egranite/quartzite — kanjani ukuthi ukumelana kwe-diamond kusenzo lokusebenza kokuqeda

Xa izigaba ze-diamond zifuna ukubonakala kakhulu, okusho ukuthi kukhona ukuphathelwa. Lokhu kusobala kakhulu ng during drilling operations ematerialini engcono njenge-granite noma quartzite. Ukugqibela okukhulu kwenza umthubi ophakeme, ngamanye amaxesha ngaphezulu kwe-600 degrees Fahrenheit, okwenzekayo ukuthi kutshintshelwe kakhulu indawo yemetalile etholakala phakathi kwediamonds. Okunyanisekile kakhulu, lokhu kungaphazanyiswa iindlela ezinentshonalanga zediamonds, zenzela ukuba zingaphansi kuka-70 kuze kube kuma-80 percent ngokungabi ngcono ekugcineni. Esikhundleni sokugcina amagugu, idrill bit ishaya kuphela esihlengalenganeni. Izinto ziya kakhulu ngemvume yesiphelo sesithuthi. Xa izigaba ziphakama kakhulu, ziqhubeka zihlobana nezixhobo zezithombe, zenza ubungakanani obukhulu obuyikhipha konke. Abasebenzi abanobuchwepheshe bafunda izinyathelo ezimbili: ukufinyelela kusabela kakhulu, ukulima kuyinkimbinkimbi, nokugqitha kuvutha. Lezi zizimpawu eziphawuliwe ukuthi ibit ayikugcina kodwa kudinga ukuthi ikhutshazwe kabefore damage iphinde iphinde.

Ukumisa kahle, ukugunya okuningi, noma ixesha elide lokudlulula — ukwahlukanisa ukuchithwa kukaqhubeka nokuhluka kwesilumo

Xa izikhwama zihlala zisebenza ngokuphucukileyo, ziqinisa, noma zilima kakhulu kunemini (kuningi kakhulu ukuya phezulu kuka-30%) oku kungumqondo wengcingo eyahlukene ofuna izisenzelo ezithile. Ukuphazamiswa kwezigaba kukho ngoba amadolozi aphazanywa phansi ngexesha kanye nezigaba siphazanywa kakhulu, okwenza i-chips zibukeke ngaphandle kwisixhobo kwaye i-cutting zibe yimali. Ukuphazanywa kwe-bond kuyahlukile. Kukhokelela xa umetali ophatha amadolozi kuphazanywa ngaphambili, uveze amadolozi aye endaweni ayifunekayo. Sizibona njengeentsindiso ezincinci eziphakathi kwesigaba, iimfazwe ezahlukileyo zokuthinta, kwaye iivibrations ezahlukileyo ngexesha lokusebenza. Kufuneka uthole indlela yokuhlola ngendlela efanelekileyo lapha. Ukuba yindlela ekuchaseneyo kuphela, ke sikhwama siyefika kisiphelo sesimo esifanelekileyo. Kodwa ukuphazanywa kwe-bond kubonisa iingcingo ezikhulu kwinkqubo esisebenzisa ngazo le sixhobo - izinto ezijonge ukuba akukho mntla omncinci wamanzi okulahla, ukugcina okuningi kakhulu, okanye ukuzula ngomgama ongaphelelanga. Lezo zidinga ukulungiswa kuqala ngaphambi kokuthatha imali engakanani kusikhwama esisha.

Imiboniso EmyaKhubazekayo Ebizoza Ukuthi Kufuneka Kuthuthukiswe Umshinakalo Wendliza Ngokushesha

Ukutheka kakhulu, ukugwema, nokuvibrisha okungavumelekile — izikhumbuzo zokuqala zokulahleka kwesithuthi noma yethemba

Kodwa ukuba umshinelwane uqale ukubonisa izimpawu zokugogoza, njengokushintsha kwembala (izitshalo zomhlaza noma zomnyama), ukuthumele umoya, futhi kusho lokuthi kuthathe, lokhu kungumtshabe wokukhona kwemisebenzi. Ukugogoza kuthinta ngempawu kumshinelwane, kwenza izindalo zihlale kancane futhi kuthinta ngempawu kumetali phakathi. Izikhatha eziphindezelayo kusuka kumzimba kusho ukuthi umshinelwane uyagcwele, futhi ukuba kukhona ukuthutha okungafanele ngexesha lokusebenza, oku kungukuthi kunezinkinga ngokwezimali noma ngokwezomthamo phakathi komshinelwane. Uma konke lokhu kuhlala, mima ukugcwebe ngokushesha futhi ushushu umshinelwane ngokuphelele. Amathuluzi okhuseleko kwezimali, kufanelwe ukufakwa kwi-OSHA futhi i-ISO 5211 yezinhlelo zezixhobo, zithi ukuthi kumelwe ukumisa imisebenzi uma lokhu kuhlala ngoba ukuzama kungakha umshinelwane ukuthi kuhlale kancane, kuthumele izinto, kuthinta lokho kusebenzayo, noma ngaphezulu kuthi kuhlale kancane umuntu osezingeni. Ukugogoza ngokwezinkwa kushintsha indima yometali ngokwezinkwa. Uma umshinelwane ugcwele ngokugogoza, akukho noma yini yokucindezela noma ukuzama ukulungisa kuyakwenzela ukuthi kubuyele emva kwesimo sakhe sokugcwebe.
