Txawm hais tias qhov kev sib raug zoo ntawm lub tshuab saw thiab qhov chaw txiav yog qhov tseeb lossis tsis ncaj qha cuam tshuam rau qhov zoo ntawm sawing. Qhov kev sib raug zoo ntawm ob qho tib si yog qhov tseeb, thiab qhov kev ua yuam kev roughness ntawm sawing nto yog me me. Thaum qhov sib piv ntawm qhov siab mus rau qhov dav ntawm qhov chaw ntsug yog sib npaug rau 2: 1, thiab thaj tsam yog 100 square metres, qhov kev ua yuam kev flatness tuaj yeem ua tiav los ntawm cov hlau saw txiav nto tuaj yeem tswj tau ntawm Tsis pub dhau 10cm, qhov tsawg kawg nkaus. tuaj yeem ncav cuag 5 cm; Yog hais tias tus txheeb ze txoj hauj lwm ntawm ob yog tsis raug, lub sawed nto yuav nkhaus, kauv los yog twisted. Txawm hais tias thaj tsam ntawm qhov block shaping nto yog tsawg tshaj li 10 square meters, tej zaum yuav muaj ib tug nkhaus nto nrog ib tug flatness yuam kev ntawm 30 cm, thiab ib tug loj-qhov chaw txiav nto Qhov flatness yuam kev qee zaum txawm mus txog 1 meter. Thaum qhov no tshwm sim, nws yuav tsis tsuas cuam tshuam qhov zoo ntawm cov blocks, txo tus nqi ntawm cov blocks, tab sis kuj cuam tshuam rau kev noj cov hlua hlau thiab kev ua haujlwm ntawm sawing. Txawm hais tias nws yog kev sib cais thiab txiav cov ore lub cev, decomposition thiab txiav ntawm ntev blocks, los yog shaping thiab txiav ntawm blocks, nws yog ib qhov tsim nyog los txiav txim siab txoj hauj lwm ntawm lub tshuab saw. Lub tshuab sawing yuav tsum txav mus rau hauv txoj haujlwm ntsug txiav ua haujlwm thiab yuav tsum tsis txhob cuam tshuam rau kev ua haujlwm ntawm lwm cov txheej txheem mining nyob ib puag ncig nws. Kev ua haujlwm ntev ntawm cov hlau pom kev tsheb ciav hlau feem ntau yog 9 meters. Thaum pib sawing, lub hauv ntej kawg ntawm lub tshuab saw yog nyob ntawm qhov tsawg kawg nkaus ntawm 1 meter ntawm lub cev ore los yog pob zeb yuav tsum tau txiav. Qhov ntev ntawm qhov chaw ua haujlwm rau lub tshuab saw yuav tsum yog tsawg kawg 11 meters. Thaum cov kauj ruam siab siab tshaj 6 meters, qhov kev ncua deb yuav tsum tau nce. Yog tias tsis muaj qhov tshwj xeeb uas yuav tsum tau ua, thaum sawing ntsug saum npoo ntawm lub cev ore, qhov txiav ntawm cov hlau saw tshuab yuav tsum ntsug rau pem hauv ntej ntawm lub cev ore. Qhov chaw ua haujlwm ntawm lub tshuab xaim sawb tuaj yeem nyob rau hauv qab lossis sab saum toj ntawm cov kauj ruam mining, tab sis hauv qab qhov chaw uas cov hlau pom tshuab tau nruab yuav tsum tiaj tus thiab ruaj khov.
