Izimayini ze-deep shaft zifuna amathuluzi agcina amandla omthelela aqinile ngisho nangaphansi kwezinga lokushisa eliphezulu kanye nomswakama. II-YT29A i-pneumatic rock drilliphumelela kakhulu kulezi zindawo ngokwedlulele ngenxa yesakhiwo sayo sepiston esiqinile kanye nosizo oluzinzile lwemilenze yomoya.

 

Uma isetshenziselwa ukunwetshwa kwe-shaft eqondile, i-YT29A ifinyeza imijikelezo yokumba, iqinisekisa ukujula kwembobo okungaguquki, futhi isiza ukugcina ubuso obuhlanzekile bokusika. Lokhu kuhumusha imijikelezo yokuqhuma okusheshayo kanyeukusebenza kahle kokukhipha i-ore.

 

Ukwakhela phezu kwalesi sisekelo esiqinile, i-YT29A ihlanganisa ukuqanjwa kwedizayini okuningana okubhekana ngqo nezinselele eziphikelela kakhulu zokumbiwa kwezinga elijulile. Isici esiyinhloko umshini wayo othuthukisiwe wokulwa ne-jamming. Ekwakhekeni kwe-geological eyinkimbinkimbi lapho i-rock strata ingahluka kakhulu ngaphakathi kwe-shaft eyodwa, ukubhola okujwayelekile kujwayele ukubamba, okubangela ukubambezeleka okubizayo kanye nomonakalo ongaba khona. Isistimu ye-valve esebenza ngokushintshashintshayo ye-YT29A ilawula ngokuzenzakalelayo ukucindezela komoya lapho ihlangabezana nokumelana, ivumela ibhithi ukuthi libe namandla ngedwala eliphukile noma ukufakwa okuthambile ngaphandle kokuma. Lokhu akugcini nje ukulondoloza ubuqotho bensimbi yokubhoboza kodwa futhi kunciphisa ngokuphawulekayo ukukhathala komsebenzisi, njengoba kunesidingo esincane sokungenelela okunamandla okwenziwa ngesandla phakathi nezigaba ezikhohlisayo.

 

Ukuqina kungenye yesisekelo sefilosofi yokuklama ye-YT29A. Izingxenye zangaphakathi, ikakhulukazi i-piston ne-chuck, zenziwe ngomgunyathi kusuka ku-proprietary, i-case-hardened alloy steel. Lokhu kukhethwa kwezinto kwenziwa ngokukhethekile ukuze kuliwe nokuguga okubangelwa ama-granite ane-quartz ephezulu nama-basalts, angehlisa ngokushesha okokusebenza okuncane. Ngaphezu kwalokho, uhlelo lokuhlunga uthuli olunezigaba eziningi ludidiyelwe ngqo ekungeneni komoya. Lokhu kubalulekile emoyeni oswakeme, oyizinhlayiyana-osindayo wemayini ejulile, lapho udaka oluhle kanye nomswakama kungakha udaka olucekela phansi ngaphakathi kwendlela yokumba, okuholela ekugqwaleni okusheshayo kanye nokuvalwa njalo kokulungisa. Ngokuqinisekisa kuphela ukuthi umoya ohlanzekile, owomile ufinyelela egumbini eliwumgogodla, i-YT29A inweba ngokumangalisayo izikhawu zesevisi, ngemibiko yasensimini evela emisebenzini eminingana emikhulu yezimayini ebonisa ukwehla okungama-40% kwesikhathi sokuphumula esingahleliwe sokulungiswa uma kuqhathaniswa namamodeli esizukulwane sangaphambilini.

 

Umthelela we-ergonomic we-YT29A kubasebenzi basezimayini awunakugcizelelwa. Iphrofayili yayo engasindi, ehlangene, ehlanganiswe nesibambo sesibambo sokudlidliza, ihlinzeka ngokulawula okuphakeme nokuhamba kahle ezindaweni ezivalekile. Umlenze womoya ozinzile wenza okungaphezu nje kokuhlinzeka ngokusekela; idala i-counter-force edonsa okuningi kwe-kickback, okuvumela opharetha ukuthi agcine ukuma okunembile isikhathi eside. Lokhu kubangela izimbobo zokuqhuma eziqondile, ezibekwe ngokunembe kakhudlwana, okubaluleke kakhulu ekuhlukaniseni kahle nokuqina kodonga. Umphumela okhulayo uyindawo yokusebenza ephephile, elawulwa kakhulu kanye nokwenza ngcono okuphawulekayo kwikhwalithi yomgodi ombiwe.

 

Ekugcineni, i-YT29A ingaphezu nje kwethuluzi; inguzakwethu wokukhiqiza oklanyelwe amaqiniso ezimayini zesimanje, ezijulile. Ngokuxazulula izinkinga eziyinhloko zokuma, ukuguga, kanye nobunzima bokusebenza, iletha izinga lokuthembeka kokusebenza elisheshisa ngokuqondile izikhathi zephrojekthi. Onjiniyela bezimayini manje sebeyakwazi ukubikezela izigaba zokumba ngokunemba okukhulu nangokuzethemba, bazi ukuthi i-YT29A ingagcina ukusebenza kwayo okulinganiselwe usuku nosuku, idlule imingcele yalokho okungenzeka ngokomnotho ekuphishekeleni ukujula kwezimbiwa phansi komhlaba.
