Kubaphathi bemigodi abajongene nobunzima obungapheliyo be-basalt yentaba-mlilo, ukusilela kwezixhobo akuyondlela ifanelekileyo—yindleko yemihla ngemihla. Njengomzi-mveliso ozinikele kuphela kubunjineli kunye nokuveliswa koomatshini bokugrumba amatye, sakhe i-I-YT29A Leg Rock Drillngqo kweli dabi. Lo matshini ngumbhobho oqinileyo, osebenza ngomoya ojolise ekugqobhozeni ngokuthe nkqo okanye okuthambekileyo kwiindawo eziphakathi ukuya kweziqinileyo. Udibanisa umzimba okhaphukhaphu kodwa oqinileyo kunye nomzimba othembekileyoumlenze womoyaukuze kuxhaswe kwaye kondliwe, okuvumela umqhubi omnye ukuba aphathe ukuseta kunye nokubhola ngokufanelekileyo. Ukusebenza kulula: qhagamshela kwi-compressor yomoya yemizi-mveliso eqhelekileyo, qinisa umatshini kwicala elililitye usebenzisa umlenze onwebekayo, kwaye ubambe i-throttle ukuze uqalise isenzo esichanekileyo, esibethayo esiqhubela phambili i-drill bit.

Kwimigodi ye-basalt, apho indalo yokurhawuzelela yelitye ikhawulezisa ukuguguleka, umahlukoYT29AIzinto eziveliswayo ziyalinganiswa. Ngaphambi kokuba zisetyenziswe, imisebenzi yayisoloko ijongene nokuma rhoqo. Iintsimbi zokubhola zaziza kufiphala ngokukhawuleza, kwaye izinto zangaphakathi ezifana neepiston kunye neesilinda kwizixhobo ezincinci ziya kuphelelwa ngamandla, nto leyo ekhokelela ekusileleni kwangethuba, iifestile zokulungisa ezinde, kunye nemveliso yemihla ngemihla engalindelekanga. Ukusukela oko kwadityaniswa i-YT29A, umahluko ucacile. Iingcango zibika ulwandiso olukhulu kumaxesha eenkonzo. Izinto zangaphakathi ze-drill eziqiniswe ngokukodwa—ezenziwe zaza zaphathwa ukuze ziqine kakhulu—zimelana ne-basalt eyohlwayayo, nto leyo enciphisa kakhulu ukuqhekeka. Olu qina luthetha ngokuthe ngqo ubomi obude kunye nokutshintshwa okuncinci. Abaqhubi ngoku bafumana ukuphazamiseka okuncinci okungacwangciswanga, begcina isantya sokubhola esihambelanayo. Isiphumo kukuphucuka okubonakalayo kwimitha yemihla ngemihla ebholwa, ukwehla kweendleko zokusebenza ngeyure ngenxa yokusetyenziswa kwezixhobo eziphantsi, kwaye ekugqibeleni, ishedyuli yemveliso eqikelelwayo nenenzuzo. Oku akusiyo nje ukuphuculwa kwezixhobo; lutshintsho lokusebenza oluya ekuthembekeni kwenye yezona ndawo zinzima kakhulu kwezemigodi.

Eyona nto iphambili kulo msebenzi ikwifilosofi yoyilo olucwangcisiweyo egxile ekuqineni ngaphezu kweenkcukacha nje kuphela. Iyunithi nganye ye-YT29A ibandakanya inkqubo yevalvu eqinisiweyo eqinisekisa ukuhanjiswa kwamandla rhoqo kwaye ikhusela ekungcoleni okuqhutywa ngumoya, ingxaki eqhelekileyo kwiimeko ze-quarry enothuli. Isilinda kunye nepiston zenziwe ngee-alloys eziphezulu kwaye ziphantsi kwenkqubo yonyango lobushushu enamanqanaba amaninzi, zidala ubunzima bomphezulu obuncinci obumelana ngokusebenzayo nokuguguleka okubangelwa luthuli lwe-basalt. Ngaphezu koko, i-air motor kunye ne-rotation mechanism zigcinwe kwindawo evaliweyo, zinciphisa kakhulu ukungena kwezinto ezincinci ezihlala zigaya iindawo ezihambayo. Olu gxininiso lobunjineli lunciphisa ukungqubana kwangaphakathi, luqinisekisa ukuba amandla omatshini adluliselwa ngokufanelekileyo kwi-drill bit endaweni yokuba achithwe njengokuguga kwecandelo langaphakathi. Kumqhubi, oku kuthetha ukuba amandla okubethela ahlala enamandla kulo lonke utshintsho, okwenza amazinga okungena akhawuleze nangona iimeko zelitye zahlukile. Uyilo lwangaphandle olulula lukwadlala indima ebalulekileyo; kunye nokuvela okuncinci kwangaphandle kunye nesimo esicwangcisiweyo, i-drill ayithambekeli kakhulu ekubambekeni nasekungonakaleni ngexesha lokuhamba kwiibhentshi ze-quarry ezinzima. Olu dibaniso lokuqina kwangaphakathi kunye nokusebenza kwangaphandle kuqinisekisa ukuba i-YT29A ayigcini nje ngokusinda kwimeko-bume ye-basalt—iyayilawula rhoqo, itshintsha emva kwenye. Isiphumo sokugqibela ngumatshini oguqula iziko elibiza kakhulu libe yimodeli yemveliso eqikelelweyo, nto leyo ebonisa ukuba ekugubungeleni imigodi enzima, izixhobo ezikhethekileyo ezifanelekileyo zezona zinto ziphambili ezisebenzayo.
