Theko ea fektheri khatello e phahameng ea moea dth rock e cheka hamore
Ho lihamore tsa 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 lihamore tsa DTH sekhahla se batlang se sa fetohe ho sa tsotelehe bolelele ba lesoba.
• Li-diameter tse nyenyane ho isa ho tse mahareng tsa ho cheka
• E sebetsa tlas'a khatello e tlaase, e khonang ho phunya bolelele bo sa tebang ho isa bohareng
