5. Kuvaka ventilation effect
Musi waMbudzi 27, 2009, bvunzo yemhepo yekufema yakaitwa pakuvhurwa kwega kwega kwega, uye mhepo yekufema yechiso chega chega chekushanda chaive chakanaka. Kutora nhamba ye10 yakarerekera shaft semuenzaniso, nzvimbo yekuvaka yakashandisa 4 kushanda zviso pakuvaka panguva imwe chete, uye hutano hwemhepo hwakasangana nehutsanana uye kuchengetedzwa kweplateau alpine tunnel yekuvaka. Zviyero zvekudzora kwezvakatipoteredza, mibairo yakayerwa inoratidzwa muTafura 5.

6. Mhedziso
6.1 Mugero weGuanjiao pari zvino ndiwo mugero wegomo wakareba kwazvo uri kuvakwa muChina. Inotarisana nematambudziko makuru ehunyanzvi mukuvaka kufefetera munzvimbo dzakakwirira, madaro marefu, uye zviso zvekushanda zvakawanda. Miyero yekufemesa mhepo inoshandiswa munyika dzakasiyana siyana pasi rose kazhinji iri pakati pe3 ne8m3/(kW·min). Zvinoenderana nemamiriro ezvinhu chaiwo munyika yangu, kuitiswa kwehutsanana zviyero zvekuvakwa kwepamusoro-soro Guanjiao tunnels inokurudzirwa.
6.2 Zvinoenderana neakasiyana siyana ekuvaka sangano mafomu anoitwa muGuanjiao Tunnel, kuburikidza nehurongwa hwekutsvagisa dzidziso uye bvunzo dzemumunda, iyo yakarongwa yekuvaka mhepo yekufefetera uye yakasanganiswa mhepo yeyakarerekera shaft clapboard nzira inorongwa, iyo inobudirira kugadzirisa dambudziko rekuvaka mhepo. Kuvakwa kwetunnel refu kwaunganidza ruzivo rwakabudirira.
6.3 Zviso zvina zvekushanda zveMutsetse 1 uye Mutsara II zvinoshandiswa pakuvaka shaft yakarerekera mukuvakwa kwenzira yakanaka panguva imwe chete. Mhedzisiro yemuyedzo inoratidza kuti kufefetedza mhedzisiro yechiso chega chega chekushanda kwakanaka, uye mhando yemhepo inosangana nezviyero zvemhepo.
