Ukulungiswa kwestope yokwemba phantsi komhlaba kuxhomekeke kakhulu ekubholeni amatye ngokukhawuleza, ngokuchanekileyo nangokungaguquguqukiyo. Ukubhomba imingxunya okucothayo okanye okungachanekanga kulibazisa ngokuthe ngqo ukuqhubela phambili kwemisele, ukwakheka kwestope kunye neeshedyuli zemveliso yesinyithi. Kumaqela emigodi yanamhlanje ajonge ukwenza lula ukuhamba komsebenzi kwindawo,YT29Aumoyaukubhola ilitye ngemilenze yomoyaIbonelela ngokusebenza okuthembekileyo kokugrumba ngesantya esiphezulu okunciphisa imijikelo yokulungiselela i-stop kwaye kuphucula ukusebenza kakuhle kokuhlela imigodi.
Ngamava obuchwephesha angaphezu kwamashumi amabini eminyaka agxile kuphela kuukubhola amatyeukwenziwa koomatshini, umzi-mveliso wethu uphucule i-YT29A air-leg rock drill ukusombulula iindawo ezibuhlungu ezihlala ixesha elide kwimisebenzi yokwemba phantsi komhlaba. Esi sixhobo sokugrumba esiphuculweyo sakhiwe ukuze simelane neemeko ezinzima zokusebenza phantsi komhlaba, sinikezela ngozinzo oluqinileyo, isantya sokugrumba esikhawulezayo kunye namazinga aphantsi okusilela xa kuthelekiswa nesiqhelo.ukuqhelisa imigodi.
I-YT29A inzima kakhuluukubhola ilitye elinomoyaYenzelwe ukwakhiwa kwamatye aphakathi ukuya kwaqinileyo, agubungela ubunzima bamatye ukusuka ku-f=8 ukuya ku-f=18. Isetyenziswa kakhulu kwimingxunya yebholithi ethe tye, ethambekileyo nephezulu kunye nemingxuma yokuqhushumba kwimijelo yemigodi engaphantsi komhlaba. Isebenza phantsi koxinzelelo lomoya oluqhelekileyo lwe-0.63MPa, umatshini ukhupha amandla okubetha azinzileyo angaphezu kwe-70J kunye nesantya sokubetha esidlula i-37Hz, enika amandla okuqhekeza amatye anamandla naqhubekayo kwindawo.
Abasebenzi kufuneka badibanise kuphela iipayipi zomoya eziqhelekileyo ezingama-25mm ububanzi bangaphakathi kunye neepayipi zamanzi ezili-13mm ukuze baqalise ukwakha. Ixhotyiswe ngeziphatho ze-ergonomic kunye neevalvu zokulawula ezibuthathaka, i-YT29A ivumela ukulungiswa okuguquguqukayo kwesantya sokubhola kunye nokuqhutywa ngokweemeko zamatye okwenyani. I-oiler yomgca we-FY250 eyakhelwe ngaphakathi ibonelela ngokuthambisa okuzenzekelayo okuqhubekayo kwiindawo zangaphakathi kuyo yonke ishifti yomsebenzi, isusa ukuphazamiseka rhoqo kokugcinwa ngesandla. Ngenxa yesakhiwo sayo esisebenziseka lula, abaqhubi abatsha banokuyiqonda ngokukhawuleza yonke inkqubo yokubhola kwaye bafikelele kumgangatho wokubhola ozinzileyo emva koqeqesho olufutshane kwindawo.
Ukuphuculwa kokusebenza kakuhle kwe-YT29A ngaphezu kweedrili zemveli zomoya-leg rock kubonakala kakhulu kwidatha yokusebenza kwemigodi yokwenyani. Uninzi lweedrili zemigodi zesiqhelo zifikelela kuphela kwi-30Hz ukuya kwi-32Hz frequency yempembelelo kunye namandla empembelelo angaphantsi kwe-55J, nto leyo ekhokelela kwisantya esicothayo sokuqhekeka kwamatye kunye nokusebenza okuphantsi kokwakha. Phantsi koyilo olufanayo lokugrumba kunye neemeko zamatye, izixhobo zemveli zithatha ixesha elingaphezulu kwe-30% ukuya kwi-40% ukugqiba imisebenzi yokugrumba ye-stope.
Kwiimeko zangaphambili zasentsimini, amaqela ezemigodi asebenzisa ukubhola amatye aqhelekileyo achitha iiyure ezili-18 ukuya kwezingama-24 ngokomyinge ukugqiba umjikelo opheleleyo wokulungiselela i-stop. Izixhobo eziphelelwe lixesha nazo zizisa ukungcangcazela okunamandla, ukudinwa kakhulu kwabasebenzi kunye nokusilela rhoqo kwezixhobo, okubangela ixesha lokungasebenzi elingalindelekanga. Emva kokuphucula ukuya kwi-athomu, abasebenzi bachitha iiyure ezili-18 ukuya kwezingama-24 besebenza.I-YT29A rock drill, umsebenzi ofanayo wokugrumba istope ungagqitywa kwiiyure ezili-10 ukuya kwezili-12, nto leyo enciphisa ixesha lokulungiselela istope phantse ngama-50%.
Isakhiwo se-YT29A esilungiselelwe kakuhle se-piston stroke kunye nokusasazwa komoya kunciphisa kakhulu ukudluliselwa kokungcangcazela, kunciphisa ukudinwa kokungcangcazela komqhubi ngama-40%. Inqanaba lengxolo yomatshini lilawulwa ngaphantsi kwama-95dB, nto leyo edala indawo yokusebenza ekhuselekileyo nekhululekileyo phantsi komhlaba. Ngokuphathelele imijikelo yozinzo kunye nokugcinwa, ukubhola kwemveli kufuna ukuhlolwa kunye nokugcinwa rhoqo emva kweeyure ezili-15 ukuya kwezingama-20 zokusebenza, ngelixa i-YT29A inokusebenza ngokuzinzileyo ngaphezulu kweeyure ezingama-60 ngokugcinwa rhoqo, nto leyo enciphisa kakhulu iindleko zokungasebenzi kunye nokugcinwa kwamashishini emigodi.
Umgangatho wemveliso ozinzileyo uvela kwimveliso esemgangathweni yefektri. Isiseko sethu semveliso siquka iimitha zesikwere ezingama-24,000, sixhotyiswe ngezixhobo zokucubungula ngokuchanekileyo ezingaphezu kwama-60 kwaye sixhaswa liqela leengcali labasebenzi abali-105 kuquka neengcali zobunjineli eziphezulu ezili-16. Yonke inxalenye ephambili ye-YT29A ihlolwa ngokungqongqo kwezinto, i-machining ngokuchanekileyo kunye nonyango lobushushu lobungcali, nto leyo ephucula ukuqina kwesixhobo nxamnye nothuli, ukufuma kunye nokungcangcazela okuphezulu kwiindawo ezingaphantsi komhlaba.
Sisebenzisa ulawulo oluqinileyo lomgangatho olusebenza ngokupheleleyo, kubandakanya uvavanyo oluqhubekayo lweeyure ezingama-72 kunye nokuhlolwa kwemveliso egqityiweyo eyi-100% ngaphambi kokuba ifike. Zonke iindawo eziphambili ziveliswa kwaye zicutshungulwa ngokuzimeleyo ngaphakathi, nto leyo esenza sikwazi ukulawula ngokungqongqo umgangatho wemveliso, uzinzo lokuhanjiswa kunye nokuhambelana emva kokuthengisa. Abathengi banokufumana iindawo ezisele ezifanayo kunye nenkxaso yobuchwephesha yobuchwephesha ngexesha elifanelekileyo ukuze kusebenze ixesha elide.
Ukongeza ekuphuculweni kokusebenza, i-YT29A izisa iingenelo ezinkulu kwezoqoqosho kwiiprojekthi zemigodi. Ukulungiswa ngokukhawuleza kwe-stope kunciphisa ngokuthe ngqo umjikelo weprojekthi iyonke, okuvumela imigodi ukuba ingene kwimveliso ye-ore esemthethweni kwiiveki ezi-2 ukuya kwezi-3 ngaphambi kwexesha eliqhelekileyo. Inkqubo ye-pneumatic ephuculiweyo inciphisa ukusetyenziswa komoya ukuya kwi-≤65L/s, ephantsi kakhulu kunokusetyenziswa komoya kwe-85L/s ukuya kwi-95L/s kwi-rock drills eqhelekileyo, inciphisa iindleko zamandla ezipheleleyo malunga ne-25%.
Ngokuqiniswa kwesakhiwo okuphuculweyo kunye nezixhobo eziphambili eziphuculweyo, i-YT29A yandisa ubomi benkonzo yecandelo kwaye inciphisa iindleko zonyaka zokutshintshwa kwezixhobo ngaphezulu kwama-40%. Ukuqinisekiswa okuninzi kweendawo zemigodi kubonisa ukuba abasebenzisi be-YT29A bafumana ukusebenza okuphezulu nge-15% ukuya kuma-20% kwimijikelo yokulungiselela i-stope. Kwangaxeshanye, inkqubo yokucoca amanzi esebenzayo ithintela ngokufanelekileyo uthuli olungaphantsi komhlaba, iphucula ukhuseleko kwindawo kwaye inciphise amandla omsebenzi wabaqhubi.
Okwangoku, i-YT29A air-leg rock drill isetyenziswa kakhulu kwimigodi engaphantsi komhlaba, ukumba imijelo kunye neeprojekthi zokumba imigodi kumazwe angaphezu kwama-20. Sihlala siphucula iinkcukacha zemveliso ngokwengxelo yehlabathi, senza i-YT29A ikwazi ukuzivumelanisa neemeko ezinzima zejoloji kunye neemfuno ezahlukeneyo zokwakha. Njengesisombululo sokumba imigodi esivuthiweyo nesingabizi kakhulu, i-YT29A iyaqhubeka nokunceda amashishini emigodi yehlabathi ukuphucula ukusebenza kakuhle kokumba, ukunciphisa iindleko zokusebenza kunye nokuzinzisa umgangatho wokwakha kwindawo.
