RC Drill

Rov qab ncig drilling, feem ntau hu ua RC Drill, yog ib hom percussion drilling uas siv cov cua compressed kom zoo thiab nyab xeeb tshem cov khoom shavings tawm ntawm lub qhov laum.

Nws yuav tsum tau pib nyob rau hauv Kalgoorlie nyob rau hauv nruab nrab ntawm lub xyoo pua 20th thaum cov pa qhib-qhov drilling tau ua pov thawj nyuaj nyob rau hauv mos hlau ore thiab ntxhia xuab zeb. Western Australians txaus siab hais tias RC Drill yog peb qhov kev tsim kho tshiab.

Technology tau dhau los ua lub sijhawm, thiab xyoo 1972 thawj qhov tshwj xeeb RC laum kav tau tsim.

Xyoo 1990, thawj RC rauj tau tsim los txhawm rau muab cov qauv txiav kom pom tseeb. High-pressure boosters tau qhia rau cov txheej txheem drilling hauv xyoo 1990 los txhim kho kev ua tau zoo thiab nce qhov nkag mus.

Vim qhov txo qis ntawm cov nqi mining, RC Drill tau tshwm sim los ua ib qho ntawm cov txheej txheem pheej yig tshaj plaws thiab meej drilling.

Cov ntaub ntawv me ntsis txog lub ntiaj teb tuaj yeem khaws tau los ntawm cov plua plav lossis txiav ntawm cov pob zeb crushed uas tau ntim khoom. Nws muaj peev xwm nrhiav tau qee yam minerals nrog qhov tseeb ntawm 0.5 mus rau 1 meters thiab txheeb xyuas lawv qhov muaj nyob. Cov hlab ntsha tiag tiag ntawm cov pob zeb hauv av thiab lawv qhov chaw nyob hauv lub ntiaj teb tuaj yeem pom hauv cov qauv tseem ceeb, uas yog qhov tseem ceeb tshaj rau tus kws tshawb fawb geologist.

Cov qauv tseem ceeb tsis yog tsim los ntawm RC drilling.

Nrog RC laum, lub qhov bore yog qhov sib txawv kiag li. Hloov chaw ntawm kev coj tus qauv los ntawm hauv av, RC drilling suav nrog ua lub qhov hauv lub ntiaj teb. Nrog RC drilling, txhua yam yog crushed ntawm lub ntsej muag me ntsis. Los ntawm kev siv huab cua siab, lub pob zeb crushed no tau txav mus rau hauv lub raj sab hauv, sab hauv mus rau saum npoo ntawm cua daj cua dub, thiab tom qab ntawd ntim los ntawm tus neeg pab. Pob zeb cuttings tsis yog ib txwm ntim. Txhua qhov chaw ntawm 6 feem pua ​​​​thiab 25 feem pua ​​​​ntawm cov txiav yuav raug siv rau kev txheeb xyuas cov pob zeb hauv av, nyob ntawm qhov xav tau ntawm geologist.

RC laum nqi tsawg dua.

Ob qho tib si overburden thiab mos, fragmented pob zeb formations yuav nkag tau los ntawm RC laum, tab sis nyuaj pob zeb yog qhov uas nws yeej ci. Vim qhov yooj yim ntawm percussive drilling thiab qhov yooj yim ntawm cov cuab yeej xav tau, nws yog tus nqi zoo. Yog tias pob zeb cov silica concentration tsis dhau, RC laum feem ntau yog 25 feem pua ​​​​rau 40 feem pua ​​​​tsawg dua li pob zeb diamond drilling.
