Imfuno yemarike yenze ukuba ukumbiwa kwentsimbi ekrwada kuhlale kunengeniso, nangona kunjalo, iiprojekthi zokwembiwa kwemigodi emincinci enzulu kakhulu kufuneka zamkele iqhinga elizinzileyo ukuba zinokugcina ingeniso yexesha elide.Kule nkalo, iirobhothi ziya kudlala indima ebalulekileyo.
Kwimigodi yemithambo emincinci, iirobhothi zokudiliza ezixineneyo nezilawulwa kude zinamandla amakhulu okusebenza.Amashumi asibhozo eepesenti abantu abonzakeleyo kwimigodi engaphantsi komhlaba bavela ebusweni, ngoko ke ukuba nabasebenzi balawule ukugrunjwa kwamatye, ukuqhushumba, ukubholithwa kunye nokuqhekezwa okukhulu kuya kugcina abo basebenzi bekhuselekile.
Kodwa iirobhothi zokudiliza zinokwenza okungakumbi kunoko kwimisebenzi yemigodi yanamhlanje.Njengoko ishishini lezimayini lisebenzela ukuphucula ukhuseleko kunye nokunciphisa impembelelo yokusingqongileyo, iirobhothi zokudiliza ezilawulwa kude zibonelela ngezisombululo ezisebenzayo kwizicelo ezahlukeneyo.Ukusuka emigodini enzulu ukuya kwimisebenzi encedisayo efana nokuvuselelwa kwemigodi, iirobhothi zokudiliza zinokunceda iinkampani zemigodi ziphucule ukusebenza kakuhle kumgodi wonke.
Ukumbiwa komthambo obhityileyo kakhulu
Njengoko imigodi engaphantsi komhlaba isiya inzulu, imingcipheko yokhuseleko kunye neemfuno zomoya, amandla kunye nenye inkxaso yolungiselelo ikhula ngokukhula.Emva kwe-bonanza yezimayini, iinkampani zemigodi zinciphisa iindleko zemigodi kwaye zinciphise ukuhluthwa ngokunciphisa ukuchithwa kwamatye enkunkuma.Nangona kunjalo, oku kubangela ukuxinana kweendawo zokusebenza kunye neemeko ezinzima zokusebenza kubasebenzi ebusweni.Ukongezelela kuphahla oluphantsi, imigangatho engalinganiyo, kunye neemeko zokusebenza ezishushu, ezomileyo nezinoxinzelelo oluphezulu, abasebenzi kufuneka balwe nezixhobo ezinzima eziphathwa ngesandla, ezinokubangela ukwenzakala kakhulu emizimbeni yabo.
Kwiimeko ezinzima kakhulu, kusetyenziswa iindlela zemveli zemigodi ezinzulu kakhulu, abasebenzi basebenza iiyure ezinde besebenza nzima besebenzisa izixhobo zezandla ezifana ne-air-leg sub-drills, abasebenzi basezimayini, kunye neepali neengalo eziyimfuneko.Ubunzima bezi zixhobo ubuncinane be-32.4 kg.Abasebenzi kufuneka banxibelelane ngokusondeleyo kunye ne-rig ngexesha lokusebenza, nokuba nenkxaso efanelekileyo, kwaye le ndlela idinga ulawulo lwe-manual ye-rig.Oku kwandisa ukuchanabeka kwabasebenzi kumngcipheko oquka ukuwa kwamatye, ukungcangcazela, ukukruneka ngasemva, iminwe ecinezelweyo kunye nengxolo.
Ngenxa yokwanda kwemingcipheko yokhuseleko yexesha elifutshane kunye nexesha elide kubasebenzi, kutheni imigodi iqhubeka isebenzisa izixhobo ezinempembelelo embi kangaka emzimbeni?Impendulo ilula: ayikho enye indlela enokusetyenziswa ngoku.Ukumbiwa kwemithambo enzulu kufuna izixhobo ezinomgangatho ophezulu wokulawuleka kunye nokuqina.Ngelixa iirobhothi ngoku zilukhetho lwemigodi exubeneyo enkulu, ezi zixhobo azifanelekanga kwimithambo emincinci enzulu kakhulu.Irobhothi yokomba yesiqhelo inokwenza umsebenzi omnye kuphela, oko kukuthi ukugrumba amatye.Oko kwathiwa, izixhobo ezongezelelweyo kufuneka zongezwe kumphezulu womsebenzi kuwo nawuphi na omnye umsebenzi.Ukongeza, ezi zixhobo zokomba zifuna icandelo elikhulu lendlela kunye nomgangatho othe tyaba xa uqhuba, nto leyo ethetha ukuba kufuneka ixesha elininzi kunye nomgudu wokugrumba imigodi kunye neendlela.Nangona kunjalo, ii-sub-rigs zomlenze womoya ziphathwa kwaye zivumela umqhubi ukuba afikelele ebusweni bomsebenzi kwi-angle efanelekileyo kakhulu ukusuka ngaphambili okanye uphahla.
Ngoku, kuthekani ukuba kukho inkqubo edibanisa iingenelo zeendlela zombini, kubandakanywa ukhuseleko oluphezulu kunye nemveliso yemisebenzi ekude kunye nokuguquguquka kunye nokuchaneka kwe-drill-leg sub-drill, phakathi kwezinye izibonelelo?Eminye imigodi yegolide yenza oku ngokongeza iirobhothi zokudiliza kwimigodi yazo enzulu.Ezi robhothi ezixineneyo zibonelela ngomlinganiselo obalaseleyo wamandla kubunzima, ipharamitha edla ngokuthelekiswa noomatshini ngokuphindwe kabini ubukhulu babo, kwaye iirobhothi zokudiliza zisebenza kakuhle kakhulu kunemibhobho engaphantsi kwemilenze yomoya.Ezi robhothi zenzelwe ezona zicelo zinzima zokudiliza kwaye ziyakwazi ukumelana nobushushu obuphezulu kunye noxinzelelo lwemigodi ye-ultra-deep.Aba matshini basebenzisa iingoma ezinobunzima beCaterpillar kunye nezinto eziphumayo ukuze basebenze kwezona ndawo zirhabaxa.I-boom enamacandelo amathathu ibonelela ngoluhlu olungazange lubonwe ngaphambili, oluvumela ukugrumba, ukugqobhoza, ukuqhekeza ilitye kunye nokubolitha kulo naliphi na icala.Ezi yunithi zisebenzisa i-hydraulic system engadingi moya ucinezelekileyo, ukunciphisa imfuno yezixhobo zobuso.Ukuqhuba kombane kuqinisekisa ukuba ezi robhothi zisebenza ngokukhutshwa kwekhabhoni eyiqanda.
Ukongeza, ezi robhothi zokudiliza zinokwenza imisebenzi eyahlukeneyo, ukwenza lula inkqubo yokusebenza kunye nokunciphisa ukukhutshwa kwekhabhoni kwindawo enzulu.Ngokutshintsha uncamathiselo olufanelekileyo, abaqhubi banokutshintsha ukusuka kwi-rock drilling ukuya kwi-bulk breaking okanye ukugqobhoza kwi-13.1 feet (4 metres) okanye ngaphezulu ukusuka ebusweni.Njengoko iteknoloji ihambela phambili, ezi robhothi zinokusebenzisa izincamatheliso ezinkulu kunezixhobo zobungakanani obuthelekisekayo, ezivumela imigodi ukuba isebenzise izixhobo ezinamandla ngakumbi kusetyenziso olutsha ngaphandle kokwandisa ubungakanani betonela yasemgodini.Ezi robhothi zinokugrumba imingxuma yebholithi ukude kunye nofakelo lwebholithi 100% yexesha.Iirobhothi ezininzi ezixineneyo kunye nezisebenzayo zokudiliza zinokusebenzisa izinamathiselo ezininzi ezijikayo.Umsebenzisi ume kumgama okhuselekileyo, kwaye irobhothi ibhobhoza emngxunyeni webholiti, ilayishe ibholithi yokuxhasa ilitye, emva koko isebenzise itorque.Yonke le nkqubo ikhawuleza kwaye iyasebenza.Ukugqitywa ngokufanelekileyo nangokukhuselekileyo kofakelo lwebholithi yophahla.
Umgodi osebenzisa iirobhothi zokudiliza kwimigodi enzulu ufumanise ukuba ukusebenzisa ezi robhothi kwehlise iindleko zabasebenzi ngama-60% ukuqhubela phambili imitha enye yobunzulu xa usebenza nezi robhothi.
