Mukuita kwekuvaka zvivakwa uye kucherwa kwemigodhi yepasi pevhu, zvinodikanwa kuchera matsime mazhinji nemigwagwa kuti aumbe hurongwa hwekusimudzira uye kuita migodhi, kucheka, uye kudzoreredza. Paunenge uchichera mashafts, kuitira kuti uwedzere uye ubvise guruva re ore rakagadzirwa panguva yekuchera uye mhepo yakasvibiswa sehutsi hwepfuti hunogadzirwa mushure mekuputika, kugadzira mamiriro ekunze akanaka emugodhi, uye kuve nechokwadi chekuchengetedzwa uye hutano hwevashandi, kuenderera mberi kwemhepo yemunharaunda yekufambisa chiso kunodiwa. Kushandiswa kwemhepo yemunharaunda yekuvandudza hutano hwemhepo yechiso chekushanda kwakajairika. Kazhinji mamiriro ekufemesa emugwagwa ane musoro mumwe wakashata zvakanyanya, uye dambudziko remhepo harina kugadziriswa zvakanaka. Zvinoenderana neruzivo rwekune dzimwe nyika rwemugodhi, kiyi ndeyekuti iyo dhayamita yemhepo inofefetera duct inoshandiswa mumhepo yemuno, uye kiyi yekuti iyo yakakodzera dhayamita yemhepo inofefetera duct inogona kushandiswa zvinoenderana nekukura kwechikamu chemugwagwa une musoro mumwe. Mupepa iri, iyo yekuverenga formula yedhayamita yehupfumi hwemhepo duct inowanikwa kuburikidza nekutsvaga. Semuenzaniso, zviso zvakawanda zvinoshanda zvemugodhi weFankou lead-zinc anoshandisa michina yedhiziri yakakura uye midziyo, uye nzvimbo yakachinjika yemugwagwa yakakura.
Zvinoenderana nemabhuku akakodzera pamusoro pekufefetedza kwemugodhi, misimboti yekusarudza dhayamita yemataipi emugodhi wemhepo ndeaya: Kana nzvimbo yekufambisa yemhepo iri mukati me200m uye vhoriyamu yekupa mhepo isiri kupfuura 2-3m.3/s, dhayamita remugodhi wekufefetera mugodhi unofanirwa kuita 300-400mm; Kana mhepo yekufambisa iri 200-500m, dhayamita remugodhi wekufefetera wemugodhi wakaiswa 400-500mm; Kana mhepo yekufambisa iri 500-1000m, dhayamita remugodhi wakaiswa mhepo yekufema; 1000m, dhayamita remugodhi wekufemesa mhepo kunofanira kuva 600-800mm. Uyezve, vagadziri vazhinji vemigodhi yekufefetera ducts vanotsanangura zvigadzirwa zvavo mumhando iyi. Naizvozvo, iyo dhayamita yemigodhi yekufefetera ducting inoshandiswa mumigodhi yesimbi uye isiri-simbi yepasi pevhu muChina yave iri mumhando ye300-600mm kwenguva yakareba. Zvisinei, mumigodhi yekune dzimwe nyika, nekuda kwekushandiswa kwemidziyo mikuru, nzvimbo yakachinjika yemugwagwa yakakura, uye dhayamita remigodhi yemhepo yekufefetera migodhi inowanzova yakakura, imwe inosvika 1500 mm, uye dhayamita yebazi remugodhi ventilation ducts inowanzopfuura 600 mm.
Mubepa rino, nhamba yekuverenga yedhayamita yemugodhi wekufemesa mugodhi wehupfumi inodzidzwa pasi pemamiriro ehupfumi mashoma emutengo wekutenga wemigodhi yekufemesa mhepo, mashandisirwo emagetsi emhepo yemuno kuburikidza nemugodhi wepombi, uye kuisirwa zuva nezuva uye kuchengetedzwa kwemigodhi ducts. Kufefetedza kwenzvimbo ine economical ventilation duct dhayamita kunogona kuita zvirinani kufefetera.
