Tlhaloso ea Motheo:
Majoe a mahareng a thata le a hlabang joalo ka majoe a lehlabathe a nang le mela ea quartz, lejoe la mokoetla le thata kapa chert, li-hematite ores, lejoe le thata, le kopantsoeng hantle la abrasive joalo ka: majoe a lehlabathe a nang le quartz binder, dolomites, quartzite shales, magma le metamorphic coarse grained rocks.
Ho Drilling ea Bochabela bo Hōle ho ka fana ka likotoana tsa ho cheka tsa tricone ka boholo bo fapaneng (ho tloha ho 3 7/8" ho isa ho 26") le boholo ba Melao ea IADC.
Ho latela thepa e sehang,tirocne bit e ka aroloa ka TCI bit le Steel Tooth Bit .API TCI trione bit. IADC517 17 1/2 "(444.5mm) e na le mofuta oa Rubber / Elastomer e tiisitsoeng ea bearing le Metal e tiisitsoeng ka tšepe. khothalletsa Metal-face sealed bearing tricone bits in drilling bits over 1000 metres, Bakeng sa ho cheka lesoba le thata le sebaka se selelele sa trenchless pilot ho feta limithara tse 300 hape re khothaletsa tšepe-face e tiisitsoeng e nang le likotoana tsa tricone. Bakeng sa ho cheka seliba sa metsi, ho cheka seliba se sa tebang kapa merero ea ho cheka mekoti e khuts'oane e se nang trenchless, elastomer(rabara) e tiisitsoeng e nang le likotoana tsa trione e na le ts'ebetso e ntle ea litšenyehelo.
