Ezimayini ezingaphansi komhlaba, ukudala izindawo zokudlula insimbi kudinga ukucaciswa okunembileukubhobozakuzo zonke izendlalelo eziyinkimbinkimbi ze-geological.I-YT29A umshini wokubhoboza idwala osebenzisa umoya inikeza ukudluliselwa kwamandla okuqinile nokuzinzile, okuqinisekisa ukungena okujulile kanye nentuthuko esheshayo.

 

Ukwakheka kwayo okuqinile kumelana kahle nedwala elinzima, kuthuthukisa isivinini sokubhoboza futhi kunciphisa isikhathi sokungasebenzi. Ezimayini ezinemijikelezo yokuqhuma njalo, lokhu kusho ukuthiukusebenza kahle kokugeleza kwe-ore okuphezulu.

 

Yakhelwe ngqo imisebenzi yokumba ngobuningi edingeka kakhulu, i-YT29A pneumatic rock drill imelela intuthuko egxile kubuchwepheshe bokumba ngaphansi komhlaba. Ibhekana ngqo nobunzima bokuthuthukiswa kokudlula kwe-ore—isigaba esibucayi lapho imishini yokumba yendabuko ivame ukwehluleka ngaphansi kwengcindezi eqhubekayo ekwakhekeni kwamadwala okungajwayelekile, okucindezela kakhulu. Okuhlukanisa i-YT29A uhlelo lwayo lokulethwa kwamandla oluthuthukisiwe. I-valve yangaphakathi kanye nokucushwa kwe-piston kwe-drill kuguqula kahle umoya ocindezelwe ube amandla okushaya ahambisanayo, kunciphisa ukulahleka kwamandla ngisho nasekujuleni okude. Lokhu kuqinisekisa ukuthi ukushaya ngakunye kuletha umthelela omkhulu wokuqhekeka, okuvumela abaqhubi be-drill ukuthi balondoloze amazinga athuthukile ngaphandle kokushintsha njalo kwamathuluzi noma ukulinganisa kabusha.

 

Ukuqina kuyisisekelo somklamo we-YT29A. Le yunithi ifaka isilinda esiqinisiwe kanye nezingxenye ze-alloy eziqinile ezimelana nokuguguleka okuvela kuma-quartzite abrasive kanye nokwakheka kwe-granitic. Ezindaweni lapho imfucumfucu yamadwala kanye nokudlidliza okuqhubekayo konakala khona ngokushesha ukubhoboza okuvamile, i-YT29A igcina ubuqotho besakhiwo ngokusetshenziswa isikhathi eside. Lokhu kuqina kunciphisa ngokuqondile ukumiswa kokulungiswa okungahleliwe—ukuhlehla okuvamile emijikelezweni yokuqhuma ehleliwe ngokuqinile.Eyamiabahleli babika ukuphazamiseka okuncane kokunakekelwa kokubhoboza, okugcina amaqembu okuthuthukisa esendleleni efanele futhi kufinyeze isikhathi phakathi kwemijikelezo yokubhoboza nokuqhuma.

 

Umthelela osebenzayo ekwakhiweni kwemigodi yensimbi ungalinganiswa. Ngokuvumela imigodi eqondile nejulile enokuphambuka okuncane, i-YT29A isiza ekudaleni iziteshi zokugeleza kwensimbi ezizinzile nezisebenza kahle. Lapho kumbiwa ukuxhumana phakathi kwamazinga, ukunemba kubaluleke kakhulu ukuze kugwenywe ukusha noma ukuqhekeka okungalingani. Ukuqina nokulawula kwemishini kuvumela abasebenzi ukuthi balandele izinhlelo ze-geological ngokunembile, kunciphisa ingozi yokuqhekeka ngokweqile noma ukuqhekeka okungaphazamisa ukunyakaza kwezinto kamuva. Ezimayini ezithembele ekuqhumeni njalo ukuze zilondoloze imigomo yokukhiqiza, ukonga ngisho namahora ambalwa ngomjikelezo ngamunye kuqongelela inzuzo enkulu njalo ngenyanga—okwandisa ukufinyelela kwenethiwekhi kanye nokusetshenziswa kwayo ngaphandle kokunyuka okulinganayo kwamahora okusebenza noma omshini.

 

Ngaphezu kwalokho, i-YT29A isebenza kahle ngaphakathi kwengqalasizinda yomoya ocindezelwe emayini ekhona, igwema isidingo sokulungiswa okubizayo. Ukwakheka kwayo kugcizelela ukulula komqhubi, ngokunciphisa i-kickback kanye nesisindo esilawulekayo, okuvumela ukushintshashintsha isikhathi eside ngokukhathala okuncane. Njengoba imisebenzi engaphansi komhlaba iqhubekela edwaleni eliqinile kanye nezindawo ezijulile, amathuluzi anjalo athembekile, akhiwe ngenhloso aba yinto ebalulekile. I-YT29A akuyona nje ukuthuthukiswa okuqhubekayo—iyisisombululo esikhethekile esiguqula ukuthuthukiswa kokudlula kwe-ore kusuka ekuvinjelweni okuphindaphindiwe kube inqubo ebikezelwayo, elula, eqinisa umgogodla wenethiwekhi yokuthutha lapho ukumba okuzinzile, okusheshayo kubaluleke kakhulu.
