1. Ukunqunywa kobubanzi bomgudu wokungenisa umoya wezimayini wezomnotho
1.1 Izindleko zokuthenga ipayipi lokungenisa umoya emayini
Njengoba ububanzi bomgudu wokungenisa umoya wezimayini bukhula, izinto ezidingekayo nazo ziyakhuphuka, ngakho-ke izindleko zokuthengwa kwepayipi lezimayini nazo ziyakhuphuka.Ngokohlaziyo lwezibalo lwenani elinikezwe umkhiqizi wepayipi lokungenisa umoya ezimayini, intengo yepayipi lemayini yokukhipha umoya kanye nobubanzi bomgudu wokungenisa umoya wezimayini ngokuyisisekelo kumugqa ngokulandelayo:
C1 = (a + bd) L( 1)
Lapho,C1- izindleko zokuthenga ipayipi lemayini lokungenisa umoya, CNY; a– izindleko ezikhuphukile zepayipi lemayini lokungenisa umoya ngobude beyunithi ngayinye, CNY/m;b– Isilinganiso sezindleko eziyisisekelo zobude beyunithi kanye nobubanzi obuthile bomgudu wokungenisa umoya wasemayini;d- ububanzi bombhobho we-ventilation yezimayini, m;L– Ubude bomgudu wokungenisa umoya wezimayini othengiwe, m.
1.2 Izindleko zembobo yokufaka umoya yezimayini
1.2.1 Ukuhlaziywa kwemingcele yendawo yokukhipha umoya
Ukumelana komoya komgudu wokungenisa umoya omayini kuhlanganisa ukumelana komoya nokungqubuzanaRfvwepayipi lokungena komoya lemayini kanye nokumelana nomoya wendawoRev, lapho ukumelana komoya wendawoRevkuhlanganisa ukumelana komoya okuhlangeneRjo, ukumelana nomoya wendololwaneRbekanye nokuphikiswa komoya kwepayipi lezimayini lokuphuma komoyaRou(uhlobo lokucindezela) noma ukumelana komoya ongenisayoRin(uhlobo lokukhipha).
Ukumelana komoya okuphelele komgudu wokungenisa umoya ocindezelayo emayini yilokhu:

Ukumelana komoya okuphelele kwe-exhaust mine ventilation duct yilezi:

Kuphi:
Kuphi:
L– ubude bomgudu wokungenisa umoya wezimayini, m.
d– ububanzi bomgudu wokungenisa umoya wezimayini, m.
s- indawo ephambanayo yomzila wokungenisa umoya wezimayini, m2.
α– I-coefficient of frictional resistance of mine ventilation duct, N·s2/m4.Ubulukhuni bodonga lwangaphakathi lomgudu wokungenisa umoya wensimbi bucishe bufane, ngakho-keαinani lihlobene kuphela nobubanzi.Ama-coefficients okumelana nokungqubuzana kwawo womabili imigudu yokungenisa umoya eguquguqukayo kanye nemigudu yokungenisa umoya eguquguqukayo enamasongo aqinile ahlobene nomfutho womoya.
ξjo- i-coefficient yendawo yokumelana yejoyinti lemayini yokungenisa umoya, engenasici.Lapho zikhonanamajoyinti kubo bonke ubude bomgudu wokungenisa umoya wezimayini, inani eliphelele lokumelana nendawo lamalunga libalwa ngokuvumelananξjo.
n– inani lamalunga epayipi lokungena komoya lemayini.
ξbs- i-coefficient yendawo yokumelana lapho kuphenduka ipayipi lemayini lokungenisa umoya.
ξou- i-coefficient yokumelana nendawo ekuphumeni komgudu wokungenisa umoya wezimayini, thathaξou= 1.
ξin- i-coefficient yokumelana nendawo endaweni yokungenisa umoya emayini,ξin= 0.1 lapho i-inlet isiyindilinga ngokuphelele, futhiξin= 0.5 – 0.6 lapho i-inlet ingeyindilinga nge-engeli elungile.
ρ- ukuminyana komoya.
Ekungeneni komoya kwasendaweni, ukumelana komoya okuphelele kwepayipi lokungena komoya lemayini kungalinganiselwa ngokususelwe phezu kokumelana komoya okuphelele nokungqubuzana.Ngokuvamile kukholakala ukuthi isamba sokumelana komoya wasendaweni kwelunga lepayipi lokungenisa umoya emayini, ukumelana komoya wasendaweni kokuphenduka, kanye nokumelana komoya kwendawo yokuphuma (uhlobo lokucindezela) noma ukumelana komoya ongenisayo (uhlobo lokukhipha) wethunjana lokungenisa umoya ezimayini cishe amaphesenti angama-20 engqikithi yokumelana komoya okungqubuzana komgudu wokungenisa umoya wasemayini.Ukumelana komoya okuphelele kokungena komoya emayini yilokhu:

Ngokusho kwezincwadi, inani le-coefficient yokumelana ne-frictional α ye-fan duct ingabhekwa njengokuhlala njalo.Iαinani le-metal ventilation duct lingakhethwa ngokusho kweThebula 1;Iαinani le-JZK series FRP ventilation duct lingakhethwa ngokusho kweThebula 2;I-coefficient yokumelana ne-frictional ye-flexible ventilation duct kanye ne-flexible ventilation duct enohlaka lwamathambo oluqinile ihlobene nokucindezela komoya odongeni, i-coefficient yokumelana ne-frictionalαinani le-flexible ventilation duct lingakhethwa ngokweThebula lesi-3.
