Mission 40 50 60 theosa le lesoba lefika phunya konopo hanyane theko
Ho cheka ha DTH, lejoe la ho phunya lejoe ke tsoelo-pele ea shank, eo piston ea rock drill e otlang ka ho toba.Kaha piston e amana ka ho toba le karolo ea ho phunya, matla a fokolang a lahleha.Sena se fa DTH ho cheka sekhahla se batlang se sa fetohe ho sa tsotelehe bolelele ba lesoba.
Mmala: Botala, Boputsoa kapa Ho ipapisitsoe le litlhoko tsa bareki
Li-bits tsa DTH li kopantsoe le lihamore tsa tsona tse lumellanang (ka ho phunya bophara ba lesoba le tlhophiso ea spline).Bareki ba ka etsa li-bits tsa bona tsa DTH ka mekhoa e fapaneng, joalo ka ho fetola profil ea tungsten carbide e kentsoeng (li-spherical, ballistic, joalo-joalo), sefahleho sa sefahleho (sefahleho se bataletseng, concave, convex, joalo-joalo), le masoba a phunyang.
