4. Ventilation dhizaini uye system marongero
4.1 Main dhizaini paramita
4.1.1 Kudzika kwekuchera. Avhareji i4.5m, uye kudzika kwekuputika kunoshanda i4.0m.
4.1.2 Huwandu hwezvinoputika. Tora 1.8kg/m3yekuchera yakazara-chikamu, uye huwandu hwekuputika kwekuputika kumwe chete i767kg. Kucherwa kwegomba rekutyaira kunotora 1.8kg/m3, uye huwandu hwechimwe chinoputika chinoputika i364kg.
4.1.3 Kupedza utsi hwemhepo nguva. Zvose zvizere-chikamu chekuchera uye parallel pilot pits zvakatorwa 20 min.
4.1.4 Mwero wekudonha kwemhepo wepasi pevhu madhakisi emhepo pa 100 metres. Tora P100=1.0%~2.0%.
4.1.5 Kana nzira yemugwagwa ichifefeterwa, mhepo yekubuda kwemhepo yemusuwo wemhepo i1.5%.
4.1.6 Indekisi yekushandiswa kwemhepo yeinjini yedhiziri mumugero mushure mekuisa iyo yekubuditsa gasi yekuchenesa mudziyo ndeye 4.0m.3/(min·kW).
4.1.7 Altitude. Tora avhareji yekukwirira kwemugero se3600m.
4.1.8 Mhepo inokweva yemhepo inogadzirisa coefficient
, kutora avhareji urefu hwenzvimbo yeGuanjiao mugero se z=3600m, ipapo
.
4.1.9 Tora friction resistance coefficient pamwe chete neventilation duct, kureva, Darcy coefficient λ= 0.012~0.015.
4.1.10 Magadzirirwo akajairwa kumhanya kwerori yekurasira i10km/h, ine mutsetse unosvika 5° kana mugwagwa usina kuenzana, sipidhi i5km/h.
4.1.11Mhepo inopikisa yemhepo inopinza uye kubuda kweiyo yakatenuka shaft. Tora No. 6 inclined shaft (2808m) semuenzaniso, mushure mokunge shaft yakarerekera ichipinda mugomba guru, kuvakwa kuchaitwa nenzira yekupinda uye kubuda kweMitsara I uye II maererano, nehuwandu hwe4 huso hwekushanda.
Iyo mhiri-chikamu nzvimbo yemhepo inopinza duct muchikamu chepamusoro cheyakarerekera shaft ndeye 17.1m.2, semicircular perimeter i 16.96m, uye dhayamita yakaenzana i4.03m. Iyo mhiri-chikamu nzvimbo ye exhaust duct muchikamu chezasi cheyakarerekera shaft ndeye 22.0m.2, rectangular perimeter i 19.88m, uye dhayamita yakaenzana i4.43m.
4.2 Dhizaini uye Sisitimu Paramita yeHybrid Ventilation Scheme muClapboard Roadway yeInclined Shaft.
Tafura 4 inoratidza dhizaini uye masisitimu maparamendi eiyo yakavhenganiswa kufefetera mumugwagwa weclapboard weimwe neimwe yakarerekera shaft. Semuenzaniso, muNo. Iyo yakagadzirirwa mhepo vhoriyamu ndeye 1800m3/ min uye kumanikidzwa kwese kuri 5000Pa. , Iyo mota simba ndeye 2 × 110kW, uye maviri-nhanho yekumhanyisa mutemo.
Tafura 4 Hybrid ventilation dhizaini uye masisitimu ma paramita ega ega akatemerwa shaft clapboard nzira.
