Tes tuav pob zeb xyaum yog feem ntau siv nyob rau hauv txawv teb chaws granite thiab marble mines raws li phau ntawv trimming ntawm blocks, drilling anchor qhov rau cov pob zeb loj drilling cov cuab yeej xws li gantry pob zeb xyaum, thiab tes tuav pob zeb drilling tshuab rau auxiliary ua hauj lwm hauv mines; Nyob rau hauv Suav teb, nws kuj siv tau rau drilling qhov kev sib tshuam qhov tob ntawm tsawg tshaj li 6m thiab threading beaded ropes. Txawm li cas los xij, nyob rau hauv cov qub granite mines hauv Brazil, tam sim no Is Nrias teb thiab Russia thiab lwm lub teb chaws, ib tug loj tus naj npawb ntawm tes tuav pob zeb xyaum siv los laum ntsug kab ntawm qhov sib cais ntev blocks ntawm pob zeb. Lub tes tuav pob zeb laum feem ntau xyaum ua kab ntawm qhov mus rau qhov tob li ntawm 6-9m, thiab qee zaum tuaj yeem xyaum qhov tob ntawm 12-18m. Qhov sib nrug ntawm qhov drilling yog cuam tshuam nrog granite splitting, drilling kev taw qhia thiab lub hom phiaj drilling, feem ntau ntawm 10-60cm. Lub tes tuav pob zeb xyaum siv cov txheej txheem txoj kab uas hla (32-42} hli) laum cov khoom thiab laum rods (txog 6.4m) rau laum kab ntawm qhov, thiab qhov drilling ceev ntawm drilling nruab nrab hardness granite yog hais txog 5-10 cm / min; laum rods kuj tseem siv tau los txuas lub tes tsho yog siv los laum qhov tob nrog qhov tob ntawm ntau tshaj 6m lossis 9m tom qab txuas cov laum rods ntawm qhov sib txawv. Vim qhov ntev ntev, cov laum rods feem ntau daig hauv qhov drilled. Tsuas yog tom qab lub pob zeb ntawm qhov sib npaug ntawm qhov ntev yog overturned lawv thiaj li raug tshem tawm. Nyob rau hauv ib tug liab-point dawb hemp granite mine ntawm Guidoni tuam txhab nyob rau hauv Brazil, tau siv los ua ib tug ntsug kab ntawm qhov tob ntawm 46m, thiab ib tug ntsug kab ntawm ntsug qhov nrog ib tug tob ntawm 53m tau ua tiav drilled. Vim hais tias ntawm qhov loj drilling qhov tob, lub mine siv tshwj xeeb 35kg tes tuav Lub pob zeb laum yog siv rau phau ntawv drilling. Qhov siab tshaj plaws ntsug drilling qhov tob ntawm lub pob zeb laum yog 60m thiab qhov drilling ceev yog 0.8m / min.
