Ulwazi oluphelele kakhulu lwezimayini zemigodi evulekile, sicela iqoqo labavukuzi
Okokuqala, ukwakheka kwezakhi ezintathu zemayini yomgodi ovulekileIzinyathelo: Itshe lensimbi lihlukaniswa libe ugqinsi oluthile lwengqimba evundlile, enqubweni yezimayini izinga lokusebenza ngalinye emkhathini lihlanganisa isinyathelo. Isinyathelo ngasinye sibizwa ngesinyathelo, futhi ukuphakama kwaso kuba ukuphakama kwesinyathelo.
I-step slope: indawo ethambekele yesinyathelo ukuya ohlangothini lwendawo yezimayini. I-engeli phakathi kwendawo ethambekele kanye nendiza evundlile ibizwa ngokuthi i-step inclination Platform (i-flat disk): indawo engaphezulu evundlile phakathi komugqa ongezansi nomugqa ongaphezulu we-slope yesinyathelo.
Ububanzi phakathi komugqa ophansi womthambeka kanye nomugqa ongaphezulu wothambeka bubizwa ngokuthi ububanzi beplathifomu, kanti ipulatifomu emisebenzini yokuqhuma, yokufosholo kanye nezokuthutha ibizwa ngokuthi iplatifomu yokusebenza; ububanzi phakathi komkhawulo wenqwaba yokuqhuma kanye nomugqa ophezulu we-slope ubizwa ngokuthi ukuphakama kwesikhulumi sokusebenza; futhi ipulatifomu esetshenziselwa ukunqamula idwala elishelelayo ibizwa ngokuthi ipulatifomu yokuphepha.
Okulandelayo, sikhuluma ngokuqondile ngenqubo yezimayini yabavukuzi bemigodi evulekile.
Okwesibili, umsebenzi wokubhoboza
Umsebenzi wokubhoboza inqubo yokuqala yokumbiwa kwemigodi evulekile, futhi kuyo yonke inqubo yezimayini yomgodi ovulekile, izindleko zokubhoboza zibalelwa ku-10% -15% wesamba sezindleko zayo zokukhiqiza.
1, Phansi imbobo rig yokumba
Ububanzi bokushintsha i-engeli yokumba imbobo ephansi, izinga eliphezulu lokusebenzisa imishini, kunciphisa isikhathi sokusebenza esisizayo, thuthukisa izinga lokusebenza kwerigi yokumba, kanye nerigi yokumba imbobo ephansi eselula futhi eguquguqukayo, isisindo semishini silula, izindleko eziphansi zokutshala imali, ikakhulukazi ukubhoboza izinhlobonhlobo zezimbobo ezitshekile ukulawula izinga le-ore, kungaqeda impande engaphansi, kunciphise amabhlogo amakhulu, futhi kuthuthukise izinga lokuqhunyiswa. Ngakho-ke, izinsimbi zokumba imigodi ephansi zisetshenziswa kakhulu ezimayini ezincane neziphakathi ekhaya naphesheya, futhi zilungele ukubhoboza amatshe ensimbi aphakathi nendawo naqinile.
2, umshini wokumba izigaxa
I-Toothed Wheel Drilling Rig iwuhlobo olusha lwesimanje lwemishini yokumba eyakhiwe ngesisekelo se-rotary drilling rig, enezici zokusebenza kahle kokubhoboza, izindleko eziphansi zokusebenza, izinga eliphezulu lemishini kanye ne-automation, futhi ilungele ukubhoboza ubulukhuni obuhlukahlukene be-automation. insimbi netshe, futhi isiphenduke insiza yokubhoboza evame ukusetshenziswa ezimayini zemigodi evulekile emhlabeni wonke.
3, unodoli omba idwala
I-Rock Drill Trolley iwuhlobo olusha lwemishini yokumba amatshe eyavela ngokuthuthukiswa kwemboni yezimayini. Kuwukubhoboza idwala okukodwa noma okuningana kanye nophephela ozishintshayo ofakwe engalweni ekhethekile yokumba noma ipulatifomu, futhi inomshini wokuhamba, ukuze umsebenzi wokubhoboza idwala uzuze umshini.
Umsebenzi wokuqhumisa
Inhloso yomsebenzi wokuqhumisa ukuhlakaza idwala eliqinile eliqinile kanye nokuhlinzeka ngokumbiwa kobukhulu obufanele bomsebenzi wokumba. Ezindlekweni eziphelele zokumbiwa kwemigodi evulekile, izindleko zokuqhumisa zibalelwa ku-15-20%. Izinga lokuqhumisa, alithinti nje kuphela ukusebenza kwezimayini, ezokuthutha, ukuchotshozwa okungekuhle nezinye izinto zokusebenza, kodwa futhi kuthinta izindleko eziphelele zemayini.
1, ukuqhuma kwembobo engajulile
Ukuqhuma kwembobo engajulile kusetshenziswa ububanzi obuncane bembobo yegobolondo, ngokuvamile eba ngu-30-75 mm, ukujula kwembobo yegobolondo. Ngokuvamile ngaphansi kwamamitha angu-5, ngezinye izikhathi kufika kumamitha angu-8 noma ngaphezulu, njengokubhoboza ngodoli we-rock drill, ukujula komgodi kungandiswa. Ukuqhuma kwemigodi engashoni kusetshenziswa ikakhulukazi ukukhiqizwa kwezimayini ezincane zemigodi evulekile noma izinkwali, ukugezwa kwamatshe, ukumba umhubhe, ukuqhuma kwesibili kokuphuka, ukucubungula iphakheji lemayini evulekile entsha, ukwakheka komthambeka we-single- ukufinyelela kokuhamba komsele odongeni nokunye ukuqhuma okukhethekile.
2, ukuqhuma kwembobo ejulile
Ukujula hi-ole blasting ukusetshenziswa kwemishini yokumba ukumba imigodi ejulile, njengendlela yokuqhuma kwendawo yezimayini. Ukuqhuma kwemigodi ejulile ezimayini zemigodi evulekile kusekelwe ikakhulukazi ekukhiqizeni ukuqhuma kwezinyathelo. Imishini yokumba imigodi ejulile isetshenziswa kakhulu ekubhobozeni okungaphansi kwamanzi kanye nokubhoboza amazinyo. Ukubhoboza kwayo kungabhoboza izimbobo ezijulile eziqondile, kodwa futhi kungabhoboza imigodi egobile. Ukulayishwa kwezimbobo ezithambekele kufana kakhulu, futhi izinga lokuqhuma kwetshe le-ore lingcono, okwenza izimo ezinhle zokumba kanye nomsebenzi wokulayisha. Ukuze kuncishiswe umphumela wokuzamazama komhlaba futhi kuthuthukiswe izinga lokuqhuma, ngaphansi kwezimo ezithile kungenziwa ezindaweni ezinkulu zokuqhuma okuhlukene, ukulayishwa noma phansi kokulayishwa kwesikhawu somoya kanye nezinye izinyathelo ukuze kuncishiswe izindleko zokuqhumisa, ukuze kuzuzwe kangcono. izinzuzo zezomnotho.
3, ukuqhuma kwegumbi
Ukuqhunyiswa kwesiphephelo kuyinani elikhulu uma kuqhathaniswa noma inani elikhulu leziqhumane, ezifakwe endleleni yokuqhuma yegumbi lokuqhuma. Izimayini zemigodi evulekile zisetshenziswa kuphela ngesikhathi sokwakhiwa kwezimali ezinkulu futhi ngaphansi kwezimo ezithile, izinkwali ngaphansi kwezimo kanye nesidingo sezimayini sikhulu kakhulu uma zisetshenziswa.
4, indlela yokuqhumisa ehlukanisa imigodi enemigqa eminingi
Eminyakeni yamuva, ngomthamo wamabhakede e-excavator kanye nokwanda okumangazayo kokukhiqizwa kwezimayini zemigodi evulekile, izidingo ezijwayelekile zezimayini zemigodi evulekile ziqhuma isikhathi ngasinye lapho inani lokuqhuma liyanda, ngenxa yalesi sizathu, ezifuywayo. kanye nezimayini zemigodi evulekile yangaphandle ekusetshenzisweni okubanzi kokuqhuma okuhlukene kwemigodi yemigqa eminingi, imigodi enemigqa eminingi ehlukanisayo yokuqhumisa i-extrusion blasting nezinye izindlela zokuqhumisa ngezinga elikhulu. Izinzuzo zokuqhunyiswa kwezinhlobonhlobo zezimbobo ezinemigqa eminingi: inani elikhulu lokuqhuma, ukunciphisa inani lokuqhuma nokugwema isikhathi sezibhamu, ukuthuthukisa izinga lokusebenzisa imishini yezimayini. ngaphansi kokuqhunyiswa kwembobo yomugqa owodwa Ukwenza ngcono ukusebenza kahle kwemishini yokubhoboza cishe ngo-10% -15%, okungenxa yokwanda kwesici sokusetshenziswa kwesikhathi sokusebenza kanye nemishini yokubhoboza kanye nokuqhuma ngemva kokunciphisa inani lemisebenzi endaweni yokugcwalisa. ukwenza ngcono ukusebenza kahle kwezimayini nezokuthutha cishe ngo-10% -15%.
5. Indlela yokuqhumisa yembobo enemigqa eminingi ehlukene
Isho inqwaba yeziqhumane ezisalele ebusweni bomsebenzi esimweni sokuqhuma okuhlukene kwemigodi yemigqa eminingi. Ukuba khona kwenqwaba ye-ballast, ukudala izimo zokukhishwa, ngakolunye uhlangothi, kunganweba isikhathi esisebenzayo sokuqhumisa, kuthuthukise ukusetshenziswa kweziqhumane nomthelela wokuchoboza; ngakolunye uhlangothi, ingakwazi ukulawula ububanzi benqwaba yokuqhuma, ukugwema ukuhlakazeka kwetshe le-ore. Isikhathi esihlukanisayo sokuminyanisa kwezimbobo zemigqa eminingi kunokuqhuma okuhlukile okujwayelekile 30% -50% ofanele, izimayini zemigodi evulekile zivame ukusebenzisa u-50-100ms.
