Ukufunwa kwemakethe kwenze ukumbiwa kwensimbi ethile kwaba nenzuzo ngokungaguquki, nokho-ke, amaphrojekthi okumba imithambo emincane emincane ejule kakhulu kufanele asebenzise isu elizinzile uma ezogcina inzuzo yesikhathi eside.Kulokhu, amarobhothi azodlala indima ebalulekile.
Ezimayini zemithambo emincane, amarobhothi okubhidliza ahlangene futhi alawulwa ukude anamandla amakhulu okusebenza.Amaphesenti angu-80 abantu abalimala ezimayini ezingaphansi komhlaba kwenzeka ebusweni, ngakho-ke ukuba nabasebenzi balawule ukubhola kwamatshe bekude, ukuqhunyiswa, ukubhowula nokuphuka kwenqwaba kuzogcina labo basebenzi bephephile.
Kodwa amarobhothi abhidlizayo angenza okungaphezu kwalokho emisebenzini yesimanje yezimayini.Njengoba imboni yezimayini isebenza ukuthuthukisa ukuphepha nokunciphisa umthelela wendawo, amarobhothi alawulwa kude ahlinzeka ngezixazululo ezisebenzayo zezinhlelo zokusebenza ezihlukahlukene.Kusukela ekumbizeni imithambo ejulile kuye emisebenzini eyisizayo njengokuvuselelwa kwezimayini, amarobhothi abhidlizayo angasiza izinkampani zezimayini ukuthuthukisa ukusebenza kahle kuyo yonke imayini.
Ukumbiwa kwemithambo emincane emincane kakhulu
Njengoba izimayini ezingaphansi komhlaba ziya ngokujula, ubungozi bokuphepha kanye nezidingo zomoya, amandla nokunye ukusekelwa kwezinhlelo kukhula ngamandla.Ngemuva kwe-bonanza yezimayini, izinkampani zezimayini zehlisa izindleko zezimayini futhi zinciphise ukuhlubula ngokunciphisa ukuchithwa kwamatshe angcolile.Kodwa-ke, lokhu kubangela ukuthi kube nezindawo zokusebenza eziminyene kanye nezimo ezinzima zokusebenza kubasebenzi ebusweni.Ngaphezu kophahla oluphansi, iphansi elingalingani, nezimo zokusebenza ezishisayo, ezomile nezinomfutho omkhulu, izisebenzi kufanele zithwale kanzima izinto eziphathwa ngesandla, ezingabangela ukulimala okubi emizimbeni yazo.
Ezimweni ezinzima kakhulu, kusetshenziswa izindlela ezijwayelekile zokumba izimayini ezijule kakhulu, abasebenzi basebenza amahora amade besebenza kanzima besebenzisa amathuluzi ezandla afana nokubhobolwa kwemilenze yomoya, abavukuzi, nezigxobo nezingalo ezidingekayo.Isisindo lala mathuluzi okungenani singama-32.4 kg.Abasebenzi kufanele baxhumane eduze ne-rig ngesikhathi sokusebenza, ngisho nokusekelwa okufanele, futhi le ndlela idinga ukulawulwa ngesandla kwe-rig.Lokhu kwandisa ukuchayeka kwezisebenzi ezingozini ezihlanganisa amatshe awayo, ukudlidliza, ukuklolodela iqolo, iminwe ephiniwe nomsindo.
Uma kubhekwa ukwanda kwezingozi zokuphepha zesikhathi esifushane nezesikhathi eside kubasebenzi, kungani izimayini ziqhubeka nokusebenzisa amathuluzi anomthelela omubi kangaka emzimbeni?Impendulo ilula: ayikho enye indlela esebenzayo njengamanje.Ukumbiwa kwemithambo ejulile kudinga okokusebenza okunezinga eliphezulu lokulawuleka nokuqina.Nakuba amarobhothi manje eseyinketho yezimayini ezixubile ezinkulu, lezi zixhobo azifanele imithambo emincane ejulile kakhulu.I-robotic drilling rig yendabuko ingenza umsebenzi owodwa kuphela, okuwukubhola ngamatshe.Sesikushilo lokho, izinto zokusebenza ezengeziwe zidinga ukungezwa endaweni yokusebenza kunoma yimuphi omunye umsebenzi.Ukwengeza, lezi zinsimbi zokumba zidinga ingxenye enkulu yomgwaqo kanye nendawo yomgwaqo eyisicaba lapho ushayela, okusho ukuthi kudingeka isikhathi nomzamo owengeziwe ukuze kumbiwe imigodi nemigwaqo.Kodwa-ke, ama-sub-rigs emilenze yomoya ayaphatheka futhi avumela opharetha ukuthi afinyelele ubuso bomsebenzi nge-engeli efanelekile kakhulu ukusuka ngaphambili noma ophahleni.
Manje, kuthiwani uma bekunesistimu ehlanganisa izinzuzo zazo zombili izindlela, okuhlanganisa ukuphepha okuphezulu nokukhiqiza kokusebenza okukude ngokuguquguquka nokunemba kwe-sub-drill yomlenze womoya, phakathi kwezinye izinzuzo?Ezinye izimayini zegolide zenza lokhu ngokwengeza amarobhothi abhidlizayo emigodini yazo ejulile.Lawa marobhothi ahlangene anikeza isilinganiso esihle kakhulu samandla nesisindo, ipharamitha evame ukuqhathaniseka nemishini kabili ngobukhulu bayo, futhi amarobhothi abhidlizayo asebenza kahle kakhulu kunokubhola okungaphansi kwemilenze yomoya yesimanjemanje.Lawa marobhothi akhelwe izinhlelo zokusebenza ezinzima zokubhidliza futhi angakwazi ukumelana namazinga okushisa aphezulu nezingcindezi zokumba izimayini ezijule kakhulu.Le mishini isebenzisa amathrekhi omsebenzi osindayo we-Caterpillar kanye nama-outriggers ukuze isebenze endaweni embi kakhulu.I-boom enezingxenye ezintathu inikeza uhla lokunyakaza okungakaze kubonwe ngaphambili, okuvumela ukubhoboza, ukubhoboza, ukugqekeza amatshe nokubhowula kunoma iyiphi indlela.Lawa mayunithi asebenzisa isistimu ye-hydraulic engadingi umoya ocindezelwe, enciphisa isidingo sezinsiza zobuso.Amadrayivu kagesi aqinisekisa ukuthi la marobhothi asebenza ngaphandle kokukhipha ikhabhoni eyiziro.
Ngaphezu kwalokho, la marobhothi abhidlizayo angenza imisebenzi eyahlukene, enze inqubo yokusebenza ibe lula futhi anciphise ukukhishwa kwekhabhoni endaweni ejulile.Ngokushintsha okunamathiselwe okufanelekile, ama-opharetha angashintsha ukusuka ku-rock drilling ukuya ekuqhekekeni kwenqwaba noma ukubhoboza ngamafidi angu-13.1 (amamitha angu-4) noma ngaphezulu ukusuka ebusweni.Njengoba ubuchwepheshe buthuthuka, lawa marobhothi angaphinda asebenzise okunamathiselwe kukhulu kakhulu kunosayizi oqhathanisekayo, okuvumela izimayini ukuthi zisebenzise amathuluzi anamandla ekusebenziseni okusha ngaphandle kokukhulisa usayizi womhubhe wezimayini.Lawa marobhothi angakwazi nokubhola izimbobo zamabhawodi ukude futhi afake amabhawodi u-100% wesikhathi.Amarobhothi amaningi ahlangene futhi asebenza ngempumelelo angasebenzisa okunamathiselwe kwe-turntable okuningi.Umsebenzisi ume ebangeni eliphephile, bese irobhothi libhoboza lingene embotsheni yebhawodi, lilayishe ibhawodi elisekela idwala, bese lifaka itorque.Yonke le nqubo iyashesha futhi iyasebenza.Ukuqedwa okuphumelelayo nokuphephile kokufakwa kwamabhawodi ophahleni.
Imayini esebenzisa amarobhothi okudiliza ezimayini ezijulile ithole ukuthi ukusebenzisa la marobhothi kwehlisa izindleko zabasebenzi ngo-60% ukuze kuthuthukiswe imitha yomugqa owodwa yokujula lapho kusebenza la marobhothi.
