Ukulungiswa kwe-stope yokumba ngaphansi komhlaba kuncike kakhulu ekubholeni amatshe okusheshayo, okunembile nokuqhubekayo. Ukumba imigodi okuhamba kancane noma okunganembile kubambezela ngqo ukuthuthukiswa kwemihubhe, ukwakheka kwe-stope kanye namashejuli okukhiqizwa kwe-ore. Kumaqembu esimanje okumba afuna ukwenza lula ukuhamba komsebenzi endaweni,I-YT29Aumoyaukubhola idwala ngemilenze yomoyaihlinzeka ngokusebenza okuthembekile kokubhoboza okusheshayo okufinyeza imijikelezo yokulungiselela i-stop futhi kuthuthukise ukusebenza kahle kokuhlela imayini iyonke.
Ngineminyaka engaphezu kwamashumi amabili yesipiliyoni sobungcweti esigxile kuphela kuukubhoboza amatsheukukhiqiza imishini, ifektri yethu ithuthukise i-YT29A air-leg rock drill ukuze ixazulule izindawo ezibuhlungu ezihlala isikhathi eside emisebenzini yokumba ngaphansi komhlaba. Leli thuluzi lokumba elithuthukisiwe lakhiwe ukuze likwazi ukumelana nezimo zokusebenza ezinzima ngaphansi komhlaba, linikeza ukuzinza okuqinile, isivinini sokumba esisheshayo kanye namazinga okwehluleka aphansi uma kuqhathaniswa nokuvamile.ukubhola izimayini.
I-YT29A inzima kakhuluumshini wokubhoboza idwala osebenzisa umoyaYakhelwe ngenhloso yokwakha amatshe aqinile aphakathi nendawo kuya kwaqinile, imboze ubulukhuni bamatshe kusukela ku-f=8 kuya ku-f=18. Isetshenziswa kabanzi emigodini yebholidi evundlile, ethambekele phezulu kanye nemigodi yokuqhuma emihubheni yezimayini engaphansi komhlaba. Isebenza ngaphansi komfutho womoya ojwayelekile ongu-0.63MPa, umshini ukhipha amandla okushaya aqinile angaphezu kuka-70J ngemvamisa yokushaya edlula u-37Hz, uletha amandla okuphuka kwamatshe anamandla futhi aqhubekayo endaweni.
Izisebenzi zidinga kuphela ukuxhuma amapayipi omoya ajwayelekile angu-25mm ububanzi bangaphakathi kanye namapayipi amanzi angu-13mm ukuze ziqale ukwakha. Ifakwe izibambo ezi-ergonomic kanye nama-valve okulawula abucayi, i-YT29A ivumela ukulungiswa okuguquguqukayo kwesivinini sokubhoboza kanye nokuqhutshwa ngokwezimo zangempela zamatshe. I-oiler yomugqa we-FY250 eyakhelwe ngaphakathi inikeza ukugcotshwa okuzenzakalelayo okuqhubekayo kwezingxenye zangaphakathi kulo lonke ishifti lomsebenzi, isusa ukuphazamiseka okuvamile kokugcinwa ngesandla. Ngenxa yesakhiwo sayo esisebenziseka kalula, abaqhubi abasha bangakwazi ngokushesha ukuqonda yonke inqubo yokubhoboza futhi bafinyelele ikhwalithi yokubhoboza ezinzile ngemuva kokuqeqeshwa okufushane endaweni.
Ukuthuthukiswa kokusebenza kahle kwe-YT29A ngaphezu kokubhola kwamatshe okwenziwa ngomoya kusobala kakhulu kudatha yokusebenza kwezimayini yangempela. Iningi lokubhola lokumba elivamile lifinyelela kuphela imvamisa yomthelela engu-30Hz kuya ku-32Hz ngamandla omthelela angaphansi kuka-55J, okuholela ekuphukeni kwedwala okuhamba kancane kanye nokusebenza kahle okuphansi kokwakha. Ngaphansi kokuhlelwa okufanayo kokubhola kanye nezimo zamatshe, imishini yendabuko ithatha isikhathi esingaphezulu kuka-30% kuya ku-40% ukuqedela imisebenzi yokubhola ye-stope.
Ezimweni zangaphambilini zasensimini, amaqembu ezimayini asebenzisa imishini yokubhola yamatshe ejwayelekile achitha amahora angu-18 kuya kwangu-24 ngokwesilinganiso ukuze aqedele umjikelezo wokulungiselela i-stop. Imishini ephelelwe yisikhathi nayo iletha ukudlidliza okunamandla, ukukhathala okukhulu kwabasebenzi kanye nokwehluleka kwezingxenye okuvamile, okubangela isikhathi sokungasebenzi esingalindelekile. Ngemva kokuthuthukela ku-I-YT29A rock drill, umsebenzi ofanayo wokubhoboza i-stope ungaqedwa zingakapheli amahora ayi-10 kuya kwangu-12, kuncishiswe isikhathi sokulungiselela i-stope cishe ngo-50%.
Isakhiwo se-piston esithuthukisiwe se-YT29A kanye nokusatshalaliswa komoya kunciphisa kakhulu ukudluliselwa kokudlidliza, kunciphisa ukukhathala kokudlidliza komqhubi ngo-40%. Izinga lomsindo lomshini lilawulwa ngaphansi kwama-95dB, okudala indawo yokusebenza ephephile nekhululekile ngaphansi komhlaba. Ngokuphathelene nemijikelezo yokuzinza nokulungisa, ukubhola okujwayelekile kudinga ukuhlolwa nokulungiswa njalo emahoreni okusebenza angu-15 kuya kwangu-20, kuyilapho i-YT29A ingasebenza ngokuzinzile amahora angaphezu kwangu-60 ngokulungiswa okuvamile, okunciphisa kakhulu izindleko zesikhathi sokungasebenzi kanye nokugcinwa kwamabhizinisi ezimayini.
Ikhwalithi yomkhiqizo ozinzile ivela ekukhiqizweni okujwayelekile kwefektri. Isisekelo sethu sokukhiqiza sihlanganisa amamitha-skwele angu-24,000, sihlonyiswe ngemishini yokucubungula enembile engaphezu kuka-60 futhi sisekelwa yithimba lochwepheshe labasebenzi abangu-105 okuhlanganisa ochwepheshe bobunjiniyela abaphezulu abangu-16. Yonke ingxenye eyinhloko ye-YT29A ihlolwa ngokuqinile izinto, imishini enembile kanye nokwelashwa kokushisa kochwepheshe, okuthuthukisa ukuqina kwemishini ngokumelene nothuli, umswakama kanye nokudlidliza okuphezulu ezindaweni ezingaphansi komhlaba.
Sisebenzisa ukulawulwa kwekhwalithi okuqinile kwenqubo ephelele, okuhlanganisa ukuhlolwa kwesimo esibi okuqhubekayo kwamahora angu-72 kanye nokuhlolwa komkhiqizo okuqediwe okungu-100% ngaphambi kokulethwa. Zonke izingxenye ezibalulekile zikhiqizwa futhi zicutshungulwe ngokuzimela ngaphakathi, okusenza sikwazi ukulawula ngokuqinile ikhwalithi yomkhiqizo, ukuzinza kokulethwa kanye nokungaguquguquki ngemuva kokuthengisa. Amakhasimende angathola izingxenye ezisele ezifanayo kanye nokusekelwa kobuchwepheshe bochwepheshe ngesikhathi esifanele ukuze kusebenze isikhathi eside.
Ngaphezu kokuthuthukiswa kokusebenza, i-YT29A iletha izinzuzo ezinkulu zomnotho kumaphrojekthi okumba. Ukulungiswa okusheshayo kwe-stope kufinyeza ngqo umjikelezo wephrojekthi iyonke, okuvumela izimayini ukuthi zingene ekukhiqizweni kwe-ore okusemthethweni amasonto amabili kuya kwamathathu ngaphambi kwezikhathi zendabuko. Uhlelo lwe-pneumatic oluthuthukisiwe lunciphisa ukusetshenziswa komoya kube yi-≤65L/s, okuphansi kakhulu kunokusetshenziswa komoya okungu-85L/s kuya ku-95L/s kokumba amatshe okuvamile, okunciphisa izindleko zamandla eziphelele cishe ngo-25%.
Ngokuqina kwesakhiwo okuthuthukisiwe kanye nezesekeli ezithuthukisiwe ze-core, i-YT29A yandisa impilo yesevisi yezingxenye futhi inciphisa izindleko zonyaka zokushintsha izingxenye ngaphezu kuka-40%. Ukuqinisekiswa okuningi kwensimu yezimayini kubonisa ukuthi abasebenzisi be-YT29A bathola ukusebenza kahle okuphezulu ngo-15% kuya ku-20% emijikelezweni yokulungiselela i-stope. Ngesikhathi esifanayo, uhlelo lokuhlanza amanzi olusebenzayo lucindezela ngempumelelo uthuli olungaphansi komhlaba, luthuthukise ukuphepha endaweni futhi lunciphise ukuqina komsebenzi womqhubi.
Njengamanje, i-YT29A air-leg rock drill esetshenziswa kakhulu ekumbeni ngaphansi komhlaba, ekumbeni imigudu kanye nasemisebenzini yokumba amatshe emazweni angaphezu kuka-20. Sihlala sithuthukisa imininingwane yomkhiqizo ngokwempendulo yomhlaba wonke, okwenza i-YT29A ivumelane nezimo zejiyoloji eziyinkimbinkimbi kanye nezidingo zokwakha ezahlukahlukene. Njengesixazululo sokumba amatshe esivuthiwe nesingabizi kakhulu, i-YT29A iyaqhubeka nokusiza amabhizinisi okumba omhlaba wonke ukuthuthukisa ukusebenza kahle kokumba, ukunciphisa izindleko zokusebenza kanye nokuqinisa ikhwalithi yokwakha endaweni.
