Imiphi imishini okufanele isetshenziselwe ukumba ku-geology enesimo sezulu esinamandla

1. I-rig yokumba ifakwe i-friction noma i-kelly bar ehlangene, engahlangabezana nobubanzi benqwaba nobude benqwaba.

2. Ibha ye-Kelly: khetha uhlobo lwepayipi lokubhoboza ngokwamandla edwala eliqine kakhulu (ngokwesibonelo, imitha eyimitha eyinqwaba ububanzi), umthamo wokugcina ungaphansi kuka-500 kPa nge-friction kelly bar; ngaphezu kuka-500 kPa enebha ehlanganisiwe ye-kelly.

3. Amathuluzi okubhoboza: Iningi lamadwala aqine kakhulu angabhobozwa ngebhakede eliphansi eliphindwe kabili lamazinyo enhlamvu ; amathuluzi okumba amakhoni amabili angaphinde asetshenziselwe ukubhola okomile. Lapho umthamo wokugcina wokuthwala ukhuphukela ku-600 kPa–900 kPa, kuyadingeka ukusebenzisa i-cartridge drill yokusika indandatho, kodwa akunakwenzeka ukuthatha ama-cores, ngakho-ke kuyadingeka ukuphinda usebenzise ukuchotshozwa okuphindwe kabili phansi.

4. Amazinyo okugaya: 30/50.22 mm amazinyo enhlamvu namazinyo e-4S bullet amazinyo asetshenziselwa ukubhoboza esimweni sezulu esiqinile, esivumela ukuchotshozwa, ukwehlisa ukumelana nokubhola, nokunciphisa ngempumelelo ukulahlekelwa.
