4. Qhov cua tsim thiab qhov system layout
4.1 Main design parameters
4.1.1 Drilling qhov tob. Qhov nruab nrab yog 4.5m, thiab qhov zoo blasting qhov tob yog 4.0m.
4.1.2 Tus nqi ntawm cov khoom tawg. Siv 1.8 kg / m3rau tag nrho-section excavation, thiab tus nqi ntawm tawg rau ib blasting yog 767kg. Lub excavation ntawm tus tsav qhov yuav siv sij hawm 1.8 kg / m3, thiab tus nqi ntawm ib lub foob pob tawg yog 364kg.
4.1.3 Lub sij hawm tso pa tawm. Ob qho tag nrho-section excavation thiab parallel pilot pits tau noj 20 min.
4.1.4 Cov pa tawm ntawm cov pa tawm hauv av hauv 100 meters. Coj P100= 1.0% ~ 2.0%.
4.1.5 Thaum txoj kev tso pa tawm, cov pa tawm ntawm lub qhov rooj cua yog 1.5%.
4.1.6 Cov huab cua noj Performance index ntawm lub cav diesel nyob rau hauv lub qhov tom qab kev txhim kho cov pa purification ntaus ntawv yog 4.0m3/(min·kW).
4.1.7 Qhov siab. Siv qhov nruab nrab qhov siab ntawm qhov av li 3600m.
4.1.8 Air gravity elevation kho coefficient
, noj qhov nruab nrab qhov siab ntawm thaj chaw Guanjiao qhov z = 3600m, tom qab ntawd
.
4.1.9 Siv cov kev sib txhuam coefficient ntawm qhov cua duct, uas yog, Darcy coefficient λ = 0.012 ~ 0.015.
4.1.10 Tus qauv tsim ceev ntawm lub tsheb thauj khoom yog 10km / h, nrog txoj kab nqes ntawm 5 ° lossis thaum txoj kev tsis sib xws, qhov ceev yog 5km / h
4.1.11Cov cua tsis kam ntawm huab cua inlet thiab qhov hluav taws xob ntawm inclined ncej. Siv 6 inclined ncej (2808m) ua piv txwv, tom qab lub inclined ncej nkag mus rau hauv lub ntsiab lub qhov, kev tsim kho yuav tsum tau ua nyob rau hauv cov kev taw qhia ntawm nkag thiab tawm ntawm kab I thiab II raws li, nrog rau tag nrho ntawm 4 lub ntsej muag ua hauj lwm.
Qhov chaw hla ntu ntawm cov cua nkag hauv cov kav dej nyob rau sab saud ntawm cov ncej inclined yog 17.1m2, lub semicircular perimeter yog 16.96m, thiab qhov sib npaug txoj kab uas hla yog 4.03m. Qhov chaw hla ntu ntawm qhov tso pa tawm hauv qhov qis ntawm qhov inclined ncej yog 22.0m2, lub voj voog ib puag ncig yog 19.88m, thiab qhov sib npaug ntawm txoj kab uas hla yog 4.43m.
4.2 Tsim thiab Txheej Txheem Parameters ntawm Hybrid Ventilation Scheme hauv Clapboard Roadway ntawm Inclined Ncej
Table 4 qhia txog tus qauv tsim thiab qhov tsis sib xws ntawm cov cua sib xyaw ua ke hauv txoj kev clapboard ntawm txhua qhov inclined ncej. Piv txwv li, hauv No. 6 inclined ncej, 125B-2110 hom counter-rotating axial flow kiv cua tuaj yeem xaiv. Tus tsim huab cua ntim yog 1800m3/ min thiab tag nrho cov siab yog 5000Pa. , Lub cev muaj zog lub cev muaj zog yog 2 × 110kW, thiab ob-theem ceev tswj.
