Enqubweni yokwakhiwa kwengqalasizinda kanye nokumbiwa kwezimayini ezingaphansi komhlaba, kuyadingeka ukumbiwa kwemithombo eminingi kanye nemigwaqo ukuze kwakhiwe uhlelo lokuthuthukisa kanye nokwenza izimayini, ukusika, nokuvuselela.Lapho kumbiwa ama-shafts, ukuze kuncishiswe futhi kukhishwe uthuli lwe-ore olwakhiwe ngesikhathi sokumba kanye nomoya ongcolile njengentuthu yesibhamu ekhiqizwe ngemva kokuqhuma, kwakha izimo zezulu ezinhle zezimayini, nokuqinisekisa ukuphepha nempilo yabasebenzi, umoya oqhubekayo wendawo ubuso bokushayela buyadingeka.Ukusetshenziswa kokungenisa umoya wendawo ukuze kuthuthukiswe izinga lomoya lobuso obusebenzayo kuvame kakhulu.Ngokuvamile isimo sokungenisa umoya somgwaqo onekhanda elilodwa sibi kakhulu, futhi inkinga yokukhipha umoya ayizange ixazululwe kahle.Ngokolwazi lwasezimayini oluthuthukisiwe lwangaphandle, okubalulekile ukuthi ipayipi elifanele lokungenisa umoya liyasetshenziswa yini endaweni yokukhipha umoya yasendaweni, futhi isihluthulelo sokuthi ingabe ipayipi lokungenisa umoya elifanele lingasetshenziswa kuncike kusayizi wesigaba esiphambanayo somgwaqo onekhanda elilodwa. .Kuleli phepha, ifomula yokubala yobubanzi bomgudu wokungenisa umoya wezomnotho itholakala ngocwaningo.Isibonelo, ubuso obuningi obusebenzayo bemayini ye-lead-zinc ye-Fankou zisebenzisa imishini emikhulu yedizili nemishini, futhi indawo ephambanayo yomgwaqo inkulu.
Ngokwezincwadi ezifanele zokungena komoya ezimayini, izimiso ezijwayelekile zokukhetha ububanzi bamapayipi okungenisa umoya ezimayini endawo yilena: Lapho ibanga lokuphakelwa komoya lingaphakathi kwama-200m futhi umthamo wokuhambisa komoya ungeqi ku-2-3m.3/s, ububanzi bomgudu wokungenisa umoya wemayini kufanele bube ngu-300-400mm; Lapho ibanga lokuphakelwa komoya lingu-200-500m, ububanzi bomzila wokungenisa umoya osetshenziswa emayini bungama-400-500mm; Ububanzi bomgudu wokungenisa umoya osetshenziswa emayini bungama-500-600mm; Lapho ibanga lokuphakelwa komoya likhulu kuno-1000m, ububanzi bomgudu wokungenisa umoya wasemayini kufanele bube ngu-600-800mm.Ngaphezu kwalokho, abakhiqizi abaningi bamapayipi okungenisa umoya ezimayini bacacisa imikhiqizo yabo kulolu hlu.Ngakho-ke, ububanzi bokudonsa umoya wezimayini osetshenziswa ezimayini zensimbi nezingezona ezensimbi ezingaphansi komhlaba eShayina ngokuyisisekelo sebuphakathi kuka-300-600mm isikhathi eside.Kodwa-ke, ezimayini zakwamanye amazwe, ngenxa yokusetshenziswa kwemishini emikhulu, indawo ephambanayo yomgwaqo inkulu, futhi ububanzi bemigudu yokungenisa umoya yezimayini yasendaweni ngokuvamile iba nkulu, eminye ifinyelela ku-1500 mm, nobubanzi bomgwaqo. Imigudu yokungenisa komoya emayini yegatsha ngokuvamile ingaphezu kuka-600 mm.
Kuleli phepha, ifomula yokubala yobubanzi bomgudu wokungenisa umoya wezimayini wezomnotho kufundwa ngaphansi kwezimo zezomnotho ezincane zezindleko zokuthengwa kwemigudu yokukhipha umoya yezimayini, ukusetshenziswa kukagesi kokungena komoya wasendaweni ngepayipi lezimayini, kanye nokufakwa kwansuku zonke. kanye nokugcinwa kwemigudu yezimayini.Ukungenisa komoya kwasendaweni okunobubanzi bepayipi lokungenisa umoya ukonga kungafinyelela umphumela ongcono wokungenisa umoya.
