0 Chiyambi

Pomanga 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 muchepetse ndi kutulutsa fumbi la ore lomwe limapangidwa panthawi yofukula ndi mpweya woipitsidwa monga utsi wamfuti wopangidwa pambuyo pa kuphulika, kupanga nyengo yabwino ya mgodi, ndikuwonetsetsa chitetezo ndi thanzi la ogwira ntchito, mpweya wabwino wamtundu uliwonse wa nkhope yoyendetsa umafunika. 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 pamigodi yakunja, chinsinsi chake ndi chakuti njira yolowera mpweya yoyenera imagwiritsidwa ntchito polowera komweko, ndipo chinsinsi chotsimikizira ngati njira yolowera mpweya yoyenera 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 akuluakulu a dizilo ndi zida, 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 ngalande ayenera kukhala 300-400mm; Pamene mpweya mtunda mtunda ndi 200-500m, m'mimba mwake wa ntchito mgodi mpweya ngalande ngalande ndi 400-500mm; Pamene mpweya mtunda ndi 500-1000m, m'mimba mwake wa mgodi ntchito mpweya mpweya mtunda; 1000m, m'mimba mwake wa mgodi mpweya mpweya ngalande ayenera kukhala 600-800mm. Kuphatikiza apo, ambiri opanga ma ducts a mpweya wabwino wa mgodi amatchula zinthu zawo 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 olowera mpweya m'derali nthawi zambiri amakhala okulirapo, ena amafika 1500 mm, ndipo m'mimba mwake ma ducts mpweya wabwino wa migodi nthawi zambiri amakhala oposa 600 mm.

Mu pepalali, mawerengedwe a kuchuluka kwa njira yolowera mpweya m'migodi yachuma amawerengedwa pansi pazovuta zachuma za mtengo wogulira ma ducts opangira migodi, kugwiritsa ntchito magetsi kwa mpweya wa m'deralo kudzera munjira ya migodi, komanso kukhazikitsa ndi kukonza ma ducts a migodi tsiku lililonse. M'dera mpweya wabwino ndi chuma mpweya ngalande m'mimba mwake akhoza kukwaniritsa bwino mpweya wabwino kwenikweni.
