Mefuta e fapaneng ea Meepo le Likotoana tsa ho Cheka Seliba

Merafo le likotoana tsa ho cheka liliba ke likotoana tse borehileng tse phunyang le ho phunyelletsa le mafika a bonolo le a thata. Li sebelisoa merafong, ho cheka liliba, ho chekoa, ho etsa likotopo, ho haha, ho hlahloba jeoloji le lits'ebetso tsa ho qhomisa.

Meepo le likotoana tsa ho cheka liliba hangata li na le khokahanyo e khoeleng bakeng sa khoele ea boro le 'mele o se nang letho oo maro a boro a tsamaisoang ka ona. Mekelikeli ea ho cheka e ea hlokahala ho tlosa likheo tsa ho phunya, ho pholisa karoloana, le ho tsitsisa lebota la sekoti. Mefuta ea likotoana tsa ho cheka liliba e kenyelletsa tse latelang:

Li-tri-cone kapa li-roller bitse na le li-cones tse tharo tse nang le meno, e 'ngoe le e 'ngoe e na le angle ea jenale e lebisitsoeng ho axis ea mantlha. The angle angle e fetotsoe ho ea ka boima ba sebopeho. Meno a khoune e 'ngoe le e 'ngoe a tobane le e 'ngoe hore a phunye mobu o thata. Bit e tsamaisoa ke boima-on-bit (WOB) ha e ntse e huloa ke ketso ea rotary ea hlooho ea drill bit.

Likotoana tsa hamore tse tlase-tlase (DTH).li sebelisoa ka lihamore tsa Down-the-hole bakeng sa ho cheka mekoti ka mefuta e mengata ea majoe. Ka kopanelo le lihamore tsa DTH, likotoana tsa hamore tsa ho cheka li entsoe ka mochini o hahelletsoeng bakeng sa ho potoloha hanyane fatše. Li-bits tsa DTH ke likotoana tsa hlooho tse sa fetoheng tse kenngoeng ka har'a matrix e mabapi le hlooho ea boro. Tlhophiso ea hlooho ea karoloana e ka ba convex, concave, kapa flat.

Likotoana tsa PDCka polycrystalline diamond compact compact (PDC) kenyang e ka bitsoa PDC bits. Ho fapana le li-tricone bits, li-drill tsa PDC ke 'mele e le' ngoe e se nang likarolo tse tsamaeang 'me e entsoe hore e tšoarelle; karolo e 'ngoe le e 'ngoe e etselitsoe ka tlung bakeng sa ts'ebetso, botsitso le ho tšepahala. Khetha Matrix kapa tšepe e matla haholo ho lumellana le lits'ebetso tse fapaneng tsa ho cheka.

Likotoana tsa likonopoli ts'oana le li-bits tsa DTH tse tsitsitseng tse nang le li-conical kapa chisel bit tse kenngoeng ka har'a matrix mabapi le hlooho ea boro. Tlhophiso ea hlooho ea karoloana e ka ba convex, concave, kapa flat. Button bit ke ntho e chitja e loketseng lisebelisoa tse ngata tsa ho cheka hamore e thata.

Likotoana tsa sefapano le likotoana tsa licheseleke likotoana tsa hlooho tse tsitsitseng tse nang le litšepe tse thata kapa li-carbide. Li-chisel bits li hlalosoa ka lehare le le leng ha li-cross bits li na le li-blade tse peli kapa ho feta tse tšelang bohare ba  biti. Hangata li-blades li theoleloa fatše ho ea holimo.
