Imigodi ye-shaft enzulu ifuna izixhobo ezigcina amandla empembelelo enamandla naphantsi kobushushu obuphezulu kunye nokufuma. II-YT29A i-pneumatic rock drilligqwesa kwezi meko zigqithisileyo ngenxa yesakhiwo sayo sepiston eyomeleleyo kunye noncedo lomlenze womoya ozinzileyo.

 

Xa isetyenziselwa ukwandiswa kweshaft ethe nkqo, i-YT29A yenza mfutshane imijikelo yokomba, iqinisekisa ubunzulu bomngxuma obungaguqukiyo, kwaye inceda ukugcina ubuso obucocekileyo bokusika. Oku kuguqulela imijikelo yokuqhushumba ngokukhawuleza kunyeukusebenza kakuhle kokutsalwa kwe-ore.

 

Ukwakha kwesi siseko sisomeleleyo, i-YT29A ibandakanya iinguqulelo ezininzi zokuyila ezijongana ngqo neyona mingeni iqhubekayo ekugrunjweni okunzulu. Olona phawu luphambili yinkqubo yayo ephucukileyo yokuchasana ne-jamming. Kwimizobo yejoloji entsonkothileyo apho istrata yamatye inokwahluka kakhulu kwishaft enye, uqheliso lwemveli luthanda ukuhlutha, lubangele ulibaziseko olunendleko kunye nomonakalo onokwenzeka. Inkqubo yevalvu ye-YT29A ilawula ngokuzenzekelayo uxinzelelo lomoya xa idibana nenkcaso, ivumela isuntswana ukuba libe namandla ngelitye elaphukileyo okanye ukufakwa okuthambileyo ngaphandle kokuma. Oku akugcini nje ukugcina ingqibelelo yensimbi ye-drill kodwa kunciphisa kakhulu ukukhathala kwabaqhubi, njengoko kungekho mfuneko encinci yokungenelela okunamandla ngesandla ngexesha lamacandelo amaqhinga.

 

Ukuqina lelinye ilitye lembombo yefilosofi yoyilo ye-YT29A. Amalungu angaphakathi, ngakumbi ipiston kunye ne-chuck, zenziwe zivela kwi-proprietary, i-case-hardened alloy steel. Olu khetho lwezinto eziphathekayo lwenziwe ngokuthe ngqo ukulwa nokuxhatshazwa okubangelwa yi-quartz content granites kunye ne-basalts, enokukhawuleza ukuthobisa izixhobo ezincinci. Ngaphezu koko, inkqubo yokucoca uthuli yamanqanaba amaninzi idityaniswe ngokuthe ngqo kwi-air intake. Oku kubaluleke kakhulu kumoya ofumileyo, wesuntswana-nobunzima bomgodi onzulu, apho intlenga yentlenga kunye nokufuma kunokwenza udaka olutshabalalisayo ngaphakathi kwendlela yokomba, ekhokelela kukonakala okukhawulezileyo kunye nokuvalwa rhoqo kogcino. Ngokuqinisekisa kuphela ucoceko, umoya owomileyo ufikelela kwigumbi eliphambili, i-YT29A yandisa ngokumangalisayo ixesha lenkonzo, kunye neengxelo zentsimi ezivela kwimisebenzi emininzi yemigodi ebonisa ukucutha kwe-40% kwixesha lokuphumla elingacwangciswanga lokulungiswa xa kuthelekiswa neemodeli zesizukulwana sangaphambili.

 

Impembelelo ye-ergonomic ye-YT29A kubasebenzi basezimayini ayinakubaxwa. Ubunzima bayo, iphrofayili edibeneyo, idibaniswe nendibano yokubamba i-vibration-dampening, inika ulawulo oluphezulu kunye nokuhamba kwiindawo ezivaliweyo. Umlenze womoya ozinzile wenza okungaphezulu nje kokubonelela ngenkxaso; yenza i-counter-force efunxa okuninzi kokukhaba, ivumela umsebenzisi ukuba agcine indawo echanekileyo ixesha elide. Oku kubangela imingxunya eqondileyo, echanekileyo ebekwe ngakumbi, eyona nto ibalulekileyo ekuqhekekeni okusebenzayo kunye nokuzinza kodonga. Isiphumo esongezelekayo yindawo yokusebenza ekhuselekileyo, elawulwa ngakumbi kunye nophuculo oluphawulekayo kumgangatho we-shaft egrunjiweyo.

 

Ekugqibeleni, i-YT29A ingaphezulu nje kwesixhobo; liqabane lemveliso elenzelwe ubunyani bale mihla, imigodi ye-shaft enzulu. Ngokusombulula imiba ephambili yokuxinana, ukunxiba, kunye noxinzelelo lwabaqhubi, inikezela ngenqanaba lokuthembeka komsebenzi elikhawulezisa ngokuthe ngqo amaxesha eprojekthi. Iinjineli zezemigodi ngoku ziyakwazi ukuqikelela izigaba zokomba ngokuchaneka okukhulu nangokuzithemba, zisazi ukuba i-YT29A inokugcina ukusebenza kwayo okulinganiselweyo imini nemini, ityhala imida yento enokwenzeka ngokwezoqoqosho kusukelo lwezona ndawo zinzulu zezimbiwa emhlabeni.
