Lub pob zeb drilling tshuab siv qhov kev sib hloov ntawm lub ratchet los ua kom lub laum pas nrig tig rau ntawm lub pob zeb kom cuam tshuam rau lub pob zeb, qhov cuam tshuam piston txav mus los, cov pa tawm tawm nkag mus rau hauv nruab nrab qhov ntawm lub laum pas nrig, thiab tshuab cov hmoov uas cuam tshuam rau lub piston. pob zeb tawm ntawm lub qhov. Raws li qhov xav tau ntawm 28-40mm carbide laum cov khoom, raws li qhov sib txawv hardness ntawm lub pob zeb, cov hlau laum cov khoom uas muaj qhov sib txawv hardness yog nruab. Raws li qhov yuav tsum tau muaj qhov loj me ntawm lub qhov, hloov cov hlau laum cov khoom ntawm qhov sib txawv, uas yog tsim rau drilling thiab blasting nyob rau hauv ntau yam mines.
Internal combustion gasoline rock drills tseem hu ua internal combustion rock drills. Vim tias nws lub cav roj av me me thiab yooj yim nqa, lub tshuab drilling tag nrho hnyav tsuas yog ntau tshaj 20 kilograms, thiab tsis tas yuav tsum tau nruab nrog cov cuab yeej pabcuam, tsuas yog nruab lub laum pas nrig, thiab lub laum me ntsis tuaj yeem ua haujlwm. Yog li ntawd, nws yog qhov tsim nyog rau cov mines uas tsis muaj cua tshuab, tsis muaj hluav taws xob, thiab kev tsim tsheb tsawg dua. Laum qhov hauv pob zeb, thiab qhov tob tshaj plaws tuaj yeem ncav cuag li rau meters vertically downwards thiab horizontally upwards tsawg dua 45 degree. Lub tshuab ua haujlwm yooj yim, txuag lub sijhawm thiab kev siv zog, thiab muaj cov yam ntxwv ntawm cov chisel ceev ceev thiab ua haujlwm siab. Tsis muaj teeb meem hauv roob siab, thaj av tiaj tus, tsis muaj teeb meem hauv 40 degree kub lossis rho tawm 40 degree txias cheeb tsam, nws tuaj yeem ua haujlwm, lub tshuab no muaj ntau yam kev hloov pauv.
Cov pob zeb drilling tshuab tau dav siv hauv kev tsuas, kev tsim kho, kev tsim khoom, kev tiv thaiv hluav taws, kev tshawb nrhiav geological, kev tiv thaiv hauv tebchaws, thiab lwm yam.
