Tam sim no, muaj ob hom tshuab txhaj tshuaj nrov nyob rau hauv kev ua lag luam, tshuaj tsuag qhuav thiab ntub dej, cov khoom siv no tau pib lig nyob rau hauv Suav teb, thiab qee qhov ntawm daim ntawv thov uas koj yuav paub txog nws yog tunnels, vaj tse, txoj kab nqes. kev tiv thaiv, thiab lwm yam. Qhov tseeb, muaj ntau tshaj li qhov ntawd, thiab cov khoom siv zoo li no xav tau nyob hauv ntau qhov chaw. Cia peb tham txog qee qhov chaw nws tuaj yeem siv tau thiab xaiv cov khoom siv li cas hauv kev tsim kho.
1. Kev tsim cov thee mines, hlau thiab tsis yog hlau mines thiab tunnels nrog roj. Nyob rau hauv hom phiaj no, peb feem ntau xaiv mining spraying tshuab. Ntawm lawv, cov mines thee, hlau thiab tsis yog hlau mine tunnels muaj ib qho me me ntawm cov tshuaj tsuag, qhov siab tsis tshua muaj qhov siab thiab qhov ntev ntawm cov tshuaj tsuag.
Qhov thib ob, daim ntawv thov hauv tunnel engineering. Cov yam ntxwv ntawm qhov tunnel spraying yog cov khoom siv loj thiab cov tshuaj txau ntau. Feem ntau, qhov kev ncua deb ntawm cov tshuaj tsuag yog luv luv thiab qhov siab yog qhov tsawg, thiab ntau lub tshuab txau yuav tsum tau siv rau kev siv tshuaj tsuag. Txawm li cas los xij, nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, tunnel anchor spraying tsheb yog siv rau cov phiaj xwm loj.
Thib peb, kev tsim kho ntawm lub hauv paus lub qhov nrog lub tshuab txau Qhov ntau ntawm cov tshuaj tsuag hauv lub hauv paus lub qhov yog me me, qhov kev ncua deb ntawm cov tshuaj yog qhov ntev, thiab qhov siab yog qhov tsawg, thiab cov tshuaj tsuag tsuag yuav tsum tau xaiv rau kev siv tshuaj tsuag me me. square spraying tshuab nrog ib qho kev ncua deb.
Plaub, kev tiv thaiv txoj kab nqes nrog cov tshuaj tsuag tshuab txoj kab nqes kev tiv thaiv kev tiv thaiv kev txau qhov deb yog qhov ntev, txoj kab nqes siab yog qhov siab, ib feem ntawm qhov chaw tsis muaj qhov chaw sib xyaw, kev siv tshuaj tsuag tuaj yeem xaiv nrog me me, qhov ntev ntawm cov tshuaj tsuag tsuag, qhov siab siab shotcrete. Tshwj xeeb, lub tshuab txau nrog kev sib xyaw tsis siv neeg thiab kev pub mis tuaj yeem xaiv tau.
