Core drilling rig yog ib hom ntawm cov tub ntxhais drilling khoom. Nws yog tsuas yog siv rau kev soj ntsuam dav dav thiab tshawb nrhiav cov hlau thiab cov khoom tsis yog xim hlau. Tsis tas li ntawd, nws tseem tuaj yeem siv rau engineering geological kev tshawb fawb, kev tshawb fawb hydrogeological, kev tshawb fawb dav dav thiab tshawb nrhiav cov roj thiab roj av, thiab dej zoo drilling. Txij li cov tub ntxhais drilling rigs xav tau kev tshem tawm ntawm qhov ua tiav, tsis sib xyaw thiab tsis muaj qhov sib txawv ntawm cov qauv pob zeb, cov tub ntxhais drilling rigs yog tag nrho cov rotary drilling rigs. Raws li cov qauv txheej txheem ntawm drilling rig rotor, core drilling rigs yuav muab faib ua peb pawg: ntsug ncej hom, turntable hom thiab mobile rotor hom.
