Pogwiritsa ntchito zomangamanga ndi migodi ya migodi pansi pa nthaka, m'pofunika kukumba zitsime zambiri ndi misewu kuti apange dongosolo lachitukuko ndikuchita migodi, kudula, ndi kubwezeretsa.Pofukula mitsinje, kuti achepetse ndi kutulutsa fumbi la ore lomwe limapangidwa panthawi yofukula ndi mpweya woipitsidwa monga utsi wamfuti wopangidwa pambuyo pa kuphulika, kumapanga nyengo yabwino ya mgodi, ndikuonetsetsa chitetezo ndi thanzi la ogwira ntchito, mpweya wabwino wopitilira wamba. nkhope yoyendetsa ndiyofunika.Kugwiritsira ntchito mpweya wabwino wa m'deralo kuti mukhale ndi mpweya wabwino wa nkhope yogwira ntchito ndizofala kwambiri.Nthawi zambiri mpweya wabwino wa msewu wokhala ndi mutu umodzi umakhala wovuta kwambiri, ndipo vuto la mpweya wabwino silinathetsedwa bwino.Malinga ndi zomwe zidachitika pamgodi wakunja, chinsinsi ndichakuti ngati njira yolowera mpweya yoyenera imagwiritsidwa ntchito polowera komweko, ndipo chinsinsi chotsimikizira ngati njira yoyenera yolowera mpweya ingagwiritsidwe ntchito zimadalira kukula kwa gawo limodzi la msewu wokhala ndi mutu umodzi. .Papepalali, njira yowerengera kukula kwa njira yolowera mpweya wabwino imapezeka kudzera mu kafukufuku.Mwachitsanzo, nkhope zambiri zogwira ntchito za mgodi wa lead-zinki wa Fankou zimagwiritsa ntchito makina ndi zida zazikulu za dizilo, ndipo mbali yodutsa msewu ndi yayikulu.
Malinga ndi mabuku okhudzana ndi mpweya wabwino wa migodi, mfundo zodziwika bwino pakusankha makulidwe a ma ducts am'deralo ndi: Pamene mtunda wa mpweya uli mkati mwa 200m ndipo voliyumu ya mpweya siposa 2-3m.3/ s, m'mimba mwake wa mgodi mpweya mpweya ngalande ayenera kukhala 300-400mm; Pamene mpweya mtunda mtunda ndi 200-500m, m'mimba mwake wa mgodi ntchito ngalande mpweya wabwino ndi 400-500mm; Pamene mpweya mtunda ndi 500-1000m, ndi m'mimba mwake wa njira yolowera mpweya wa mgodi ndi 500-600mm; Pamene mtunda wokwanira wa mpweya uli wokulirapo kuposa 1000m, m'mimba mwake mwa njira yolowera mpweya mumgodi uyenera kukhala 600-800mm.Kuphatikiza apo, ambiri opanga ma ducts a mpweya wabwino wa mgodi amafotokozera zomwe amagulitsa mosiyanasiyana.Choncho, m'mimba mwake wa migodi mpweya mpweya ducting ntchito zitsulo ndi sanali zitsulo pansi migodi ku China wakhala mu osiyanasiyana 300-600mm kwa nthawi yaitali.Komabe, m'migodi yakunja, chifukwa chogwiritsa ntchito zida zazikulu, njira yodutsa msewu ndi yayikulu, ndipo m'mimba mwake ma ducts otulutsa mpweya wa migodi nthawi zambiri amakhala wamkulu, ena amafika 1500 mm, ndi m'mimba mwake ma ducts mpweya mpweya mu nthambi nthawi zambiri kuposa 600 mm.
Mu pepalali, mawerengedwe a kuchuluka kwa njira yolowera mpweya mu mgodi wachuma amawerengedwa pansi pazifukwa zochepa zachuma za mtengo wogulira ma ducts opangira mpweya wa migodi, kugwiritsa ntchito magetsi kwa mpweya wakumaloko kudzera munjira ya migodi, komanso kukhazikitsa tsiku lililonse. ndi kukonza njira zodutsira migodi.M'deralo mpweya wabwino ndi chuma mpweya wolowera m'mimba mwake angakwaniritse bwino mpweya wabwino kwenikweni.
