Ezindaweni zezimayini zaseNew Zealand—kusukela ezimayini zegolide eziqinile zase-Otago kuya ezingqimbeni ezihlangene ze-West Coast yaseSouth Island—ukuhlola ukushisa (imifantu emincane yokushisa) emazinyweni ahlanganisiwe edayimane kuwukubulala umkhiqizo buthule. Ngikubonile mathupha: i-drill bit isebenza kahle amahora amaningi, bese iyancipha ngokuzumayo njengoba imifantu emincane isakazeka kuyo yonke i-cutter, okuphoqa ukuthi kumiswe okungahleliwe ukuze kushintshwe amathuluzi. Ngemva kwamasonto ayi-10 okuhlolwa emayini yegolide yaseCentral Otago,Izinyo elihlanganisiwe ledayimane elithambilekusuka ku-Ninestones Superabrasives isibe yisisombululo sethu esibalulekile. Lokhu akuyona nje indlela engcono yokusika—kuwubufakazi bokuthi i-Ninestones iyaqonda izinselele ezihlukile zokushisa kwezimayini zase-NZ, futhi ukuzibophezela kwayo ekuxazululeni izinkinga zangempela kuyenza ibe ngumlingani othembekile wemisebenzi yasendaweni.
Umsuka Wokuhlola Ukushisa: Kungani Amazinyo Ajwayelekile Eqhekeka Ngaphansi Kokushisa
Ukuhlolwa kokushisa akwenzeki ngengozi—kuwukungqubuzana phakathi kwemikhawulo yezinto zokwakha kanye nezimo ezinzima zokumba. Okokuqala, kukhona ukungalingani kokukhula kokushisa**: njengoba i-NZ Mining Technology Portal yaphawula ngo-2024, idayimane kanye ne-carbide substrate yayo zinamazinga okukhula kokushisa ahlukene kakhulu (idayimane ku-~1.5×10⁻⁶/℃, i-carbide ku-~5×10⁻⁶/℃). Lapho kubholwa idwala eliqinile, ukungqubuzana kusunduza amazinga okushisa angaphezu kuka-200℃, futhi lokhu kungafani kudonsa izinto ezimbili zihlukane, kudala imifantu emincane.
Okwesibili, amazinyo ajwayelekile abamba ukushisa: imiklamo yawo eyisicaba noma emikhulu ayivumeli ukushisa kuphume ngokushesha, ngakho-ke izindawo ezishisayo zakheka onqenqemeni lwanamuhla. Njengoba i-"Industrial Diamond Review" iveze ngonyaka odlule, lezi zindawo ezishisayo zingakhuphuka ziye ku-300℃ ngemizuzu eyi-10, ziguqule imifantu emincane ibe yizimbobo ezigcwele. Emayini yase-Otago, sihlole amazinyo amathathu edayimane ajwayelekile—wonke athuthukisa ukuhlolwa kokushisa zingakapheli amahora ama-5, kanti elilodwa lahluleka ngokuphelele. Kwaze kwaba yilapho sishintshela ku-Ninestones'Izinyo elihlanganisiwe ledayimane elithambileukuthi sibone umehluko wangempela: ukwakheka kwayo kuhlose kokubili ukungalingani kokunwetshwa kanye nokwakheka kokushisa, okuyizimbangela ezimbili ezinkulu zokuqhekeka kokushisa.
Izinyo elihlanganisiwe ledayimane elithambile: Umklamo we-Ninestones Wokulwa Nokushisa
I-Ninestones ayizange nje ilungise umshini wokusika ojwayelekile—yakhaI-toot ehlanganisiwe yedayimaneh kusukela phansi kuya phezulu ukuze kulwiwe nokuhlolwa kokushisa. Ukunqoba kokuqala ukuma kwayo okuyindilinga: ngokungafani namazinyo asicaba abamba ukushisa, ubuso obubushelelezi bekhoni buvumela umoya kanye ne-coolant ukuthi kugeleze ngokukhululeka, kuthwale ukushisa okweqile. Ekuhlolweni kwethu, izinga lokushisa lobuso bomsiki lahlala liphansi ngo-40% kunamazinyo ajwayelekile, ngisho nalapho kubholwa i-granite engu-2.8g/cm³.
Bese kuba nobuchwepheshe bezinto ezibonakalayo: I-Ninestones isebenzisa inqubo yokushisa ephezulu (bayibiza ngokuthi “i-Thermal Bond Tech”) enciphisa ukungalingani kokunwebeka phakathi kwedayimane ne-carbide ngo-35%. Njengoba ithimba labo lobuchwepheshe lichazile, lokhu kubopha izingqimba ezimbili ngokuqinile kangangokuthi ukushisa akukwazi ukuzihlukanisa—yilokho kanye okunconywa yi-“Diamond Technology Review” ukuze kube nokuzinza kokushisa.Izinyo elihlanganisiwe ledayimane elithambilefuthi inesendlalelo sedayimane esijiyile (1.2mm vs. 0.8mm emazinyweni ajwayelekile), okwenza kube "nendawo yokugqoka" eyengeziwe ngaphambi kokuba imifantu ifike endaweni engaphansi komhlaba. Emayini yase-Otago, lokhu kwahunyushwa emahoreni ayi-12 okubhoboza okuqhubekayo ngaphandle kokuhlola ukushisa—okungaphezu kokuphindwe kabili kwesikhathi sokuphila sabasiki abajwayelekile.
Inzuzo yesithathu ukuzivumelanisa nezimo: I-Ninestones yenzaIzinyo elihlanganisiwe ledayimane elithambilengobubanzi obukhethekile (kusukela ku-8mm kuya ku-19mm) kuma-drill rig avamile ase-NZ. Sasidinga inguqulo engu-13mm yemayini yethu yamalahle yase-West Coast, futhi bayiletha emavikini ama-2—akukho ukubambezeleka okuvamile “okulingana nosayizi owodwa” konke. Yilolo hlobo lokuguquguquka oludingwa yibavukuzi base-NZ, ikakhulukazi lapho usuku ngalunye lokungasebenzi lubiza izinkulungwane.
Kungani Ama-Ninestones Evelele: Ngaphezu Kokuhlinzeka Ngomsiki Wezitini
Okwenza iNinestones ihluke ngempela akuyona nje kuphelaInhlanganisela yedayimane ethambile nayoth—ukuzinikela kwabo ekuxazululeni izinkinga *zethu*. Ngokungafani nabaphakeli baphesheya abathumela umkhiqizo bese benyamalala, ithimba labo landiza laya endaweni yethu yase-Otago ukuyoqeqesha ithimba lethu ngokuphathwa kokushisa: indlela yokulungisa ukugeleza kwe-coolant ngesimo sekhoni, indlela yokubona ukuhlolwa kokushisa kusenesikhathi (ngaphambi kokuba lonakalise izinyo), ngisho nendlela yokufanisa umshini wokusika nezinhlobo ezahlukene zamatshe.
Baphinde basekele umkhiqizo wabo ngedatha yangempela: yonkeIzinyo elihlanganisiwe ledayimane elithambileiza nombiko wokuhlolwa kokushisa, ofakazela ukuthi iyahlangabezana nezindinganiso ezinzima zezimayini zase-NZ. Lapho sinombuzo mayelana nokusebenzisa umshini wokusika ezinhlotsheni zobumba oluphezulu (obamba ukushisa okwengeziwe), onjiniyela babo abakhuluma isiNgisi babuyela kithi emahoreni ama-4—ngokushesha kunanoma yimuphi umhlinzeki wendawo esike sasebenza naye. Omunye umvukuzi eGreymouth washintshela eNinestones ngonyaka odlule wangitshela ukuthi, “Sasivame ukushintsha abasiki kabili ngokushintshana; manje kuba kanye njalo ezinsukwini ezintathu.” Yilolo hlobo lokuthembeka oluguqula abaphakeli babe abalingani.
Ukuze uthole imininingwane eyengeziwe mayelanaIzinyo elihlanganisiwe ledayimane elithambile, ukucela ikhotheshini eyenziwe ngokwezifiso yezimo zezimayini zase-NZ, noma ukuthola umhlahlandlela wokuphathwa kokushisa we-Ninestones, xhumana nalokhu:

Mayelana Nombhali: UJake Fraser, odabuka eChristchurch, eNew Zealand, uneminyaka eyi-11 yesipiliyoni njengochwepheshe wezokusebenza kwezimayini. Usebenze ezindaweni ezibalulekile zezimayini zase-NZ—e-Otago, eWest Coast, naseNorthland—egxile ekuxazululeni izinkinga zokwehluleka kwamathuluzi ezindaweni eziqinile kanye nokwakheka kokushisa okuphezulu. Ubuchwepheshe bakhe bokusebenza ngezandla buye basiza izimayini zase-NZ ukunciphisa izindleko zamathuluzi ngo-30% ngokwesilinganiso, futhi uvame ukuncoma ama-Ninestones Superabrasives kontanga. “Izinyo labo elihlanganisiwe le-Diamond taper aligcini nje ngokunciphisa ukuhlolwa kokushisa,” usho kanje. “Kuwubufakazi bokuthi inkampani elalela abavukuzi ingakha amathuluzi asebenzela ngempela izimo zethu ezihlukile zase-NZ.”
