Mukuita kwekuchera mugero, kuitira kunyungudutsa uye kuburitsa utsi hwepfuti, guruva, muchetura uye anokuvadza magasi anogadzirwa nekuputika, uye kuchengetedza mamiriro akanaka ekushanda, zvinodikanwa kufefetera kumeso kwekuchera mugero kana dzimwe nzvimbo dzekushanda (kureva, tumira mweya mutsva).Asi pari zvino, mukuvakwa kwekuchera mugero, kusarudzwa uye kuenzanirana kwemichina yekufemesa nemidziyo, uye kutonga kwehuwandu hwemhepo uye kumhanya kwemhepo kunonyanya kuenderana neruzivo.Ichi chinyorwa chinosuma muchidimbu maitiro ekuona iyo ventilation mhepo uye sarudza michina mukugadzira tunnel yekuchera.
1. Ventilation uye kushandiswa kwayo
Iyo yekufemesa modhi inotarwa zvichienderana nehurefu hwemugero, nzira yekuvaka uye mamiriro emidziyo, uye yakakamurwa kuva marudzi maviri: kufefetedza kwepanyama uye mechanical ventilation.Kufefetedza kwemusikirwo ndiko kushandisa mutsauko wemumhepo wemuchadenga pakati pemukati nekunze kwemugero wekufemesa pasina mishini;)Maitiro maviri ekutanga emagetsi ekufambisa mhepo (press-in ventilation uye extraction ventilation) inoratidzwa muiyo basic ventilation mode diagraph yekuvaka tunnel (Mufananidzo 1);kusanganisa kufefetedza ndiko kusanganiswa kwemaitiro maviri ekutanga ekufemesa, ayo akakamurwa kuva refu-pressure uye pfupi-kuburitsa, refu-kudzvanywa uye refu-kumanikidza ventilation.Short-pressing type (kumberi-kudzvanya uye kumashure-kudzvanya mhando, kumberi-kudzvanya uye kumashure-kudzvanya mhando).Iko kushandiswa uye zvakanakira uye zvisingabatsiri zveumwe neumwe ndezvizvi zvinotevera (ona Tafura 1).
Tafura 1 Kushandiswa uye kuenzanisa kwezvakanaka uye zvisingabatsiri zvezvinowanzo shandiswa nzira dzemhepo mukugadzira tunnel.
| Ventilation | Inoshanda tunnel mhando | Kuenzanisa zvakanakira nekuipira | ||
| Natural ventilation | Tunnel dzine hurefu husingasviki 300 metres uye isina gasi rinokuvadza rinogadzirwa nematombo ematombo aanopfuura kana kana tunnel holing-kuburikidza nemhepo. | Zvakanakira: hapana michina michina, hapana simba rekushandisa, hapana mari. Kuipa: yakakodzera chete tunnels mapfupi kana tunnel holing-kuburikidza nemhepo. | ||
| Mechanical Ventilation | Press-in ventilation | Inokodzera matani epakati uye mapfupi | Zvakanakira: Kumhanya kwemhepo uye kunoshanda kunoshanda pakubuda kweponji yemhepo yakakura, kugona kweutsi hwemhepo kwakasimba, nguva yekufema yechiso chekushanda ipfupi, flexible ventilation duct inonyanya kushandiswa, mutengo wakaderera, uye iwo. inowanzoshandiswa mukugadzira tunnel. Zvakaipa: Mhepo inodzoka inosvibisa mugero wose, uye kubuda kunononoka, izvo zvinokanganisa nzvimbo yekushanda. | |
| Extraction ventilation | Inokodzera matani epakati uye mapfupi | Zvakanakira: Guruva, muchetura uye magasi anokuvadza anopinzwa zvakananga mufeni, uye anoburitswa mugero kuburikidza nefeni, pasina kusvibisa dzimwe nzvimbo, uye mamiriro emhepo uye nharaunda yekushanda mugero inoramba yakanaka. Zvakaipa: Iyo spiral ventilation ducts inotora flexible layflat ventilation duct ine simbi waya skeleton kana yakaoma mhepo duct, uye mutengo wakakwira. | ||
| Hybrid ventilation | Marefu uye akawedzera-kureba tunnel anogona kushandiswa, ane musanganiswa wekubvisa uye kudzvanya-mumhepo | Zvakanakira: Kufefetedza kuri nani. Zvakaipa: Maseti maviri emafeni uye mhepo ducts zvinodiwa. Zvimwe zvakanakira nekuipira zvakafanana nekudzvanya-mukati uye kuburitsa kufefetera. | ||
