Qhov ntawd yog ib qho kev piav qhia muaj zog thiab meej ntawm lub sijhawm tseem ceeb hauv cov pob zeb nyuaj tunneling.
Kev Npaj: "Mobilizing rau lub ntsej muag"
Ua ntej nws nkag mus, thaj chaw yog ib qho kev ua ub ua no:
Kev Npaj Lub ntsej muag: Cov khoom tawg dhau los ntawm cov khib nyiab ("muck") tau raug tshem tawm los ntawm cov tsheb thauj khoom thiab thauj cov tsheb thauj khoom. Lub ntsej muag pob zeb uas tau tshwm sim tshiab yog scaled (cov pob zeb xoob tshem tawm) thiab tshuaj xyuas.
Kev teeb tsa kev siv hluav taws xob: Cov qhov cua nkag tau txuas ntxiv, cov kab hluav taws xob tau tso tawm, thiab cov kab dej rau kev tiv thaiv plua plav txuas nrog.
Cov Lus Qhia Kawg: Tus neeg tsav tsheb laum thiab tus thawj coj ua haujlwm saib xyuas tus qauv xyaum- daim ntawv qhia meej ntawm qhov twg txhua qhov yuav tsum tau drilled, raws li lub qhov geology thiab qhov profile xav tau.
Nws Lub Hom Phiaj Tseem Ceeb: Thawj kauj ruam hauv kev xyaum & tawg voj voog
Lub jumbo txoj haujlwm yog los ua kom tiav "drill" theem ntawm Drill-Blast-Muck- Lub voj voog txhawb nqa:
Precision Drilling: Siv nws lub computerized system, tus neeg teb xov tooj tso txhua qhov boom los xyaum qhov (feem ntau 3-}5 meters sib sib zog nqus) hauv cov qauv tawg tshwj xeeb (hluav taws kub, V-txiav, thiab lwm yam). Cov qauv no ua kom cov pob zeb tawg tau zoo thiab qhov zoo ntawm lub qhov.
Qhov Kev Npaj: Txhua qhov drilled tom qab yuav raug them nrog cov khoom tawg (xws li ANFO), stemmed (plugged), thiab xaim rau detonation.
Vim Li Cas Lub Sij Hawm no tseem ceeb
Tus Pace-Setter: Qhov kev ua tau zoo ntawm jumbo teem lub sijhawm rau tag nrho lub voj voog tunneling. Kev nrawm dua, qhov tseeb dua qhov drilling txhais tau tias ntau lub voj voog ib zaug.
Precision Engineering: Niaj hnub nimno jumbos siv laser kev taw qhia thiab computerized tswj los xyuas kom meej qhov drilled nyob rau hauv millimeters ntawm txoj kev npaj. Qhov no tsis txhob overbreak (nkim sij hawm / khoom siv) los yog underbreak (tawm hauv pob zeb uas xav tau rov ua dua-drilling).
Kev Nyab Xeeb Frontline: Nws yog thawj cov khoom siv loj los koom nrog lub ntsej muag tshiab, uas tsis muaj kev ruaj ntseg tom qab tawg. Kev tiv thaiv pob zeb ntog thiab kev ruaj ntseg neeg ua haujlwm cabins yog qhov tseem ceeb.
