Ukuthi isithi sokubhulwa sikhuthaza njani ukusebenza ngokubhula kwesilime

Kungani ukungabonakali kwezilime nokuphakeme kwayo kuyadinga ukuvuselela kwezithi sokubhulwa

I-Limestone inenqubo eziningi zokubhalwa kakhulu. Iyavamile ngaphakathi kwe-3 ne-4 kusuka kusikhwama se-Mohs sokuphakeme kanye nesikhala esingakanani sokubulawa, lezi zinqubo zibonisa izinkinga ezingaphansi zokubhalwa kwezinkampani zokubhalwa. Le ndawo iyisofthu kakhulu ukuthi amabhalwa ayafika kumkhiqizo kusheshile, kodwa ngoba akukho bulawa obuningi, ukubulawa kwemithombo yamabhalwa akufanele kufana nokubulawa okufanele. Lokhu kunciphisa indlela yokubulawa uma usebenzisa imithombo eyisikhulu kakhulu kule ndawo. Ngaphandle kwalokho, uma imithombo iyisofthu kakhulu, zibulawa kusheshile nakuba le ndawo ayibulali kakhulu. Ukufumana iziphumo ezinembile kudinga ukuthola isibalance esihle phakathi kokuqinisa i-diamonds emsebenzini futhi ukuvumela ukuthi sebenze kahle. Abaprofesiwane abaningi bafindile ukuthi imithombo yametal yezikhulu kahle ibaluleke kakhulu ngoba iyabulawa ngendlela efanele futhi ibe yisikhulu kakhulu kwe-diamonds ngaphandle kokwenza ubulawa obuningi kwezisekhondi zabo. Uma abantu baphepha lokhu okubaluleke kakhulu, izinkampani zabo zibulawa kusukela ku-30% ku-50% kusheshile uma zisebenza ne-limestone kungeza ne-granite ngokwesifundo sasemva sezirhantsho zokubhalwa zasezindustria esayishwe ngo-2023.

Ukuchaphazeka okuphundutse: amathuba amathathu (amathuba amabili-ebonded) vs amathuba amathathu (amathuba amanikeli-ebonded)

Ukuchaza okukhulu phakathi kwezinkulungwane zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zez......

Ukusebenza kwe-Drilling nokuhle kwezindlela: Isikhathi, isikhephe, nokuphila kwezinqamula e-limestone

Izinqamula zesiliva zezinkulungwane zisindisa ngokuphelele xa zidrillisa e-limestone ngoba izinkulungwane zihlanganisiwe kuzo ngendlela eyodwa kumatrix wemetalu. Lokhu kusindisa ukuthi ukubuka kufana nezinye izinto kusindisa ukuthi kusike kakhulu ngokushesha kumaqhaza amaningi. Lezi zinqamula zidrillisa ngokwesibini ngama-1.5 kuze kube ama-2.5 inches ngomzuzu ngaphezu kwezinkulungwane ezingu-20 ngokugcina, ngoba izinkulungwane ezingasho ziyagcina ukudlala njengoba zihlukile. Ngaphakathi kwalokho, izinqamula zezinkulungwane zezincwadi zisindisa ngokushesha kakhulu ekudlaleni emaphakathini amancane, ngokwesibini kungaba yizinkulungwane ezingu-20 kuze kube ezingu-30% kushesha kakhulu, kodwa ukusebenza kwazo kusindisa ngokushesha kakhulu emva kwezinkulungwane ezingu-15 kuze kube ezingu-20. Kungani? Ngoba zinaleyo ilayiya yekuphakanyiswa kwamazinkulungwane, ngakho-ke ukubuka kufana nezinye izinto kusindisa kuleli lelayiya kuphela. Lokhu kusindisa isikhephe kude kakhulu kunezinkulungwane ezingu-600 Fahrenheit xa kusebenza ngokugcina, futhi uma kufika lapho, i-limestone isindisa ukudlala kwezinkulungwane ezincane esithi zimicrofractures.

Lapho kusetshenzwa ngamaphrojekthi adinga ukucacisa okuphezulu njengemininingwane yezakhiwo, ukuzinza kokushisa kwama-bit agxishiwe kusiza ukugcina ubuqotho bomgodi ngoba awahlushwa izinkinga zokugeleza kokushisa. Izingcezu ezihlotshisiwe zisasebenza kahle emisebenzini edinga ukuwela okukodwa kuphela ezintweni lapho ukwenza umsebenzi ngokushesha kubaluleke ngaphezu kwesikhathi esihlala ngaso, uma nje kugcinwa ukuchithwa okufanele kuyo yonke inqubo. Zombili lezi zinhlobo zidinga ukugeleza kwamanzi okuhle ukuze zisebenze kahle, kodwa ama-bit agxishiwe aphatha izinguquko ekugelezeni kwamanzi kangcono kakhulu kunalawo agxishiwe, okubaluleke kakhulu lapho kuhlolwa itshe le-limestone elinezinguquko ezingalindelekile zokuqina ezigabeni ezahlukene zetshe

Ukusebenza kwesikhathi eside: izingcezu ezifakwe i-sinter ekujuleni noma ekuphindaphindeni kwe-limestone core

Koduku kusebenzisa izibhamu zokubhukha ezincane zokubhukha kwe-limestone ephambili noma kuzo zonke izindlela zokubhukha ngokuphinda-phinda, izibhamu zesiliva zokubhukha zezindiza ziyadlala indima yabo yokugcina. Indlela okuyenzelwa ngayo lezi zibhamu ngokufaka izindiza ngokujulile kusuka kumkhakha wesiliva kuyinika ubukhulu bokugcina ukuthi zingaphela ngokushesha njengoba zisebenza ngokuphelele. Izibhamu zokufaka akuzange zihambisane ngalesi simo ngoba ngenxa yokuba izibhamu zesiliva zihlala zifana ngokushesha ngokusebenza, izinye zezindiza ezintsha ziyagcina ziyagcina ngokuzenzakale. Le ndima yokugcina ngokuzenzakale iyanciphisa ukuthi abasebenzi bayaqhubeka kanjani nokuguqula izibhamu emva kweminye isikhathi sokusebenza. Abakhi abasebenza ngokuphinda-phinda ngokubhukha amabhukhu amaningi ngokuphambili kubantu ababhekene nezinsizakalo zokubhukha kungqondweni okanye kubantu ababhekene nezinsizakalo zokuhamba ngaphansi kwamandla, bafunda ukuthi ngenxa yokuba izibhamu zesiliva ziyathenga kakhulu kuqala, kodwa ziyasusa imali ngokuphambili ngoba ngalokho umsindo wokubhukha uyisilinganiso esincane kabanzi. Ngaphezu kwalokho, lezi zibhamu ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha kunezinye ngoba ziyagcina ngokushesha k......

Ukuthola kwezinsuku ezincane: izihlangothi eziyaphakanyiswa ukwenza izihlangothi ezincane, eziphakade nokuthi zingahleli ngokupheleleyo ngenani elincane lokuseta

Amaphakathi amadimondi ayo atholakala ngokwekholiweyo ayisifanekile kakhulu ukudlula izihlangothi ezincane kwe-limestone uma kufakwa izinto zokusebenza kwezilwanyana noma ukuthumela iziqu zokusebenza kwezilwanyana ngaphakathi kwemithambo. Okukhombisa ukuthi bahlukene ngokujulile kukuthi bahlula ngokuphelele ngaphandle kokuthenga kakhulu ukusobala. Lezi zikhethi zinezinhlobo zezindimondi ezingalunye kuphela ezibonakalayo ngokubambisana ne-nickel, okwenza ukuthi inhlangothi yokuhlula ibe encane kakhulu. Lokhu kuthabatha ukuthi izihlangothi ziyohlula ngokucleana ngaphandle kokuchitha kwezinye izihlangothi, okuyisidingo esikhulu uma ukufaka kuyakubonwa ngabantu abasebenzisa noma abavumela. Isidingo esinye? Akukho nkonzo yokuvula kabefore ukusebenzisa futhi kusho kakhulu ukuthi besebenza ngendlela efanele ngaphandle kokuthi kubhekwe inkululeko. Lokhu kusiza abasebenzisi ukuthi bafake ngokushesha kwezihlangothi zokuhlula ngokushesha. Kumaqhaza amancane apho umuntu akufuna ukudlula izihlangothi ezingu-10 nje futhi isihlangothi sisheshi kungafika ku-2 inches, lezi zikhethi zisiza ukuthi ubhaleke ngokuncane ngoba akukho nkonzo yokuthenga izinkululeko zokuhlula ezinengcwele. Kuyakwazi ukuthi azizaleli kakhulu kwe-limestone, kusho kakhulu ukuthi zisebenza ngokuphelele kuma-20 ku-30 izihlangothi, kodwa ukuxhumana nokuthi zingasewo kakhulu nokuthi zisewo kushesha ngaphansi kwe-15 minutes, zisiza kakhulu, ikakhulu uma isikhathi sisikhefu kweqhaza.

Imatrikhi yokugcina isiphakeme: ukulwandisa uhlobo lwesibhakabhaka nendlela yokubhaka, ubude bewa, inombolo yamaphepha, nokulingana kwezinkimbinkimbi zemithombo

Ukukhetha indiza yezindiza zomkhosi we-diamond eyodwa kulezi zintandabuzo ezintathu:

Amaphakathi we-diamond esihlwayo ayasebenza kahle kakhulu kwezindlela zokukhupha izilwane zemithambo yelimestone ngokujulile futhi xa kufakwa amaphakathi amaningi ngokuvamile ngoba abhekise isikhombisa semaphakathi we-diamond futhi abhekise ukuthi bakhawuleka kahle kwezimithambo. Xa kufakwa kungaphezulu kwe-50mm noma kufakwa amaphakathi angaphezu kwe-50, lezi maphakathi abuyela ngokugcina amasikhombisa ngokuphakeme kwe-30% nangoba bayegcina imali kahle ngokwesikhathi sokuthenga ngokwesikhathi sokuqala ngokubonakalisa izinkomba ezenziwe ngokuziphatha kwezimithambo. Amaphakathi we-electroplated ayasebenza kahle kwezindlela zokufaka ezincinci lapho ukuthi kwenziwe kahle kusiza kakhulu. Isiqinisekiso esibalulekile: khetha umaphakathi ofanele ngokubhekisele kumandla wokufaka owenayo. Lezi maphakathi esihlwayo zidinga ukuthi zibe nesikhathi sezindaba esingaphezu kwe-800 watts, kodwa lezi maphakathi we-electroplated ziyasebenza kahle ngesikhathi sezindaba esingaphezu kwe-500 watts.

Izinkinga eziphikisana — kungani ‘isithunywa esincinci = isibhelo esincinci’ kuyisibongo sokulinganisa isilimestone

Ukukholelwa ukuthi ubulukhuni obuphakathi kwe-limestone (cishe 3 kuya ku-4 esikalini sika-Mohs) kusho ukuthi sidinga izibopho ezithambile ezihlanganisiwe akunakwenzeka uma ubheka amaqiniso angempela esayensi yezinto ezibonakalayo. Itshe le-limestone lingase libe mnene kunegranite, kodwa ukuqina kwalo okuphansi akweneli ukuba kugqoke lezo zinhlayiya ze-nickel zibe izingcezu ezihlotshisiwe futhi kuveze amadayimane amasha. Esikhundleni salokho, izingcezu ziqala ukufiphala ngokushesha futhi zigule ngokungafani ebusweni. Nokho, lapho sibheka izibopho zensimbi ezifakwe i-sinter, zihlala isikhathi eside ngamaphesenti angu-40 uma zisetshenziswa e-limestone ngoba amadayimane avezwa kancane kancane njengoba i-matrix iguga ngokwemvelo. Lokhu kwakha lo mphumela wokuvuselelwa kwesendlalelo sedayimane oqhubekayo ongeke kwenzeke ngalezo zingcezu ezenziwe ngogesi ezingengqimba olulodwa. Futhi kukhona okunye okufanele kukhulunywe ngetshe le-limestone: lezo ziqu ze-silica eziqukethwe yiyo empeleni zisheshisa ukuwohloka kwama-bit agqokiwe. Ngakho nakuba itshe likalamula lingeyona into enzima kakhulu, abasebenza kulo bathola ukuthi izingcezu ezifakwe i-sinter zigcina zibiza kancane uma kuziwa emisebenzini yokumba emikhulu.
