Emaphrojekthini okwandisa izitimela zasemadolobheni, ukuqhumisa iziteshi kuwumsebenzi obalulekile futhi onobungozi obukhulu. Njengomkhiqizi ogxile ku-ukubhoboza amatsheimishini, sethula i-YT28i-drill yedwala yomlenze womoya—imishini yezinga lobuchwepheshe eyenzelwe izindawo ezivalekile nezidinga ukunemba.YT28Ihlanganisa umklamo olula kodwa oqinile womoya kanye nohlelo lokusekela imilenze oluzinzile, okuvumela abaqhubi ukuthi benze ukubhoboza imigodi yokuqhuma okunembile ezindaweni eziqinile. Imodi yayo yokubhoboza emanzi icindezela ngempumelelo uthuli, inciphisa ukukhiqizwa kokushisa, futhi yandisa impilo yezingxenye zokubhoboza, kuyilapho indlela yokushaya ebushelelezi iqinisekisa amandla okushaya ahambisanayo, inciphisa ukuphambuka ngesikhathi sokubhoboza. Izimpawu zokubeka ezicacile kanye nama-engeli emilenze alungisekayo kusiza kakhulu ekufinyeleleni ukulungiswa kwemigodi okunembile, okubalulekile ekugwemeni ukulimala kwezakhiwo zemihubhe ezikhona kanye nokuqinisekisa imiphumela yokuqhuma elawulwayo.

Ngaphambi kokusebenzisa i-YT28, izindawo eziningi zokumba kanye nezindawo zokufaka imihubhe zazithembele ekubholeni kwamatshe okuvamile noma ezindleleni zokubhoboza ngesandla, okwakuvame ukuholela ezinseleleni ezifana nokuphambuka kwemigodi, ukudlidliza ngokweqile, kanye nokungcola kothuli. Lezi zinkinga zaholela emiphumeleni yokuqhuma engalingani, izingozi zokuphepha ezingaba khona, kanye nesikhathi eside sephrojekthi. Ngemva kokushintshela ku-YT28, abaqhubi babike ukuthuthuka okukhulu: ukunemba kokubhoboza kukhuphuke cishe ngo-40%, ngamaphutha okuqondanisa imigodi ancishiswe abe ngaphakathi kuka-3 cm ezingqimbeni zamadwala eziyinkimbinkimbi. Uhlelo lokubhoboza olumanzi luphinde lwathuthukisa izimo zokusebenza ngokunciphisa amazinga othuli olusemoyeni ngaphezu kuka-80%, okuthuthukisa ukubonakala nokuphepha kokuphefumula kwabasebenzi. Kuphrojekthi yokwandiswa kwesiteshi sikamasipala yamuva endaweni yasemadolobheni eyakhiwe kakhulu, i-YT28 yenze osonkontileka bakwazi ukuqedela isigaba sokubhoboza sokukhulisa amasonto amabili ngaphambi kwesikhathi, ngaphandle kwezehlakalo zomonakalo odongeni lomhubhe oluseduze. Ukuqina kwemishini kwabonakala njengoba igcina ukusebenza okuzinzile ngokusebenza okuqhubekayo ezindaweni ezinomswakama, ezihlukumezayo ngaphandle kokuguga okukhulu.

Kwabathuthukisi bengqalasizinda kanye nochwepheshe bokufaka imihubhe, i-YT28 imele okungaphezu nje kokubhoboza—iyithuluzi elinembile elilinganisela amandla, ukulawula, kanye nokuphepha komqhubi. Umklamo wayo ubonisa ulwazi lweminyaka eminingi lwefektri yethu ekuthuthukiseni izixazululo zokumba amatshe zezinhlelo zokusebenza ezingaphansi komhlaba eziyinselele. Sinikeza ukwesekwa okugcwele kobuchwepheshe, okuhlanganisa isiqondiso endaweni yokuma kwemilenze, ukulungiswa kwemvamisa yomthelela, kanye nokugcinwa kohlelo lokushaya oluvalwe ngamanzi. Iyunithi ngayinye ihlolwa ngaphansi kwezimo zesikhala esilinganiselwe ngaphambi kokulethwa ukuqinisekisa ukuthembeka. Njengoba amadolobha emhlabeni wonke andisa amanethiwekhi awo okuhamba ngaphansi komhlaba, isidingo semishini yokubhoboza enembile, esebenza kahle, futhi ephephile siyaqhubeka nokukhula. Ukubhoboza idwala lemilenze ye-YT28 kuhlangabezana nalesi sidingo ngokuguqula imisebenzi eyinkimbinkimbi yokubhoboza ibe imisebenzi elawulekayo, ebikezelwayo—ekugcineni okunikela ekuthuthukisweni kwengqalasizinda yasemadolobheni ephephile, esheshayo, futhi engabizi kakhulu.
