Tricone Bit Folasaga
Tricone bit o se tasi o meafaigaluega autu mo le pu faʻafefe ma vai vaieli viliina.O lona soifuaga ma faatinoga pe talafeagai mo le viliina pe leai, e i ai se aafiaga tele i le tulaga lelei, saoasaoa ma le tau o le viliina galuega.
O le ma'a ta'e e le tricone bit lea sa fa'aogaina i la'u o lo'o galue ma le a'afiaga o nifo ma le sele e mafua mai i le pa'u o nifo, lea e maua ai le maualuga o le gau o le papa ma le tau maualalo.
O tricone bits na atiina ae ma gaosia e le JCDRILL e masani ona faʻaaogaina mo le lapopoʻa o le lua eli, e pei o le koale matala, mines uʻamea, mines apamemea ma mines molybdenum, faʻapea foʻi ma mines e le o uʻamea, vai vaieli.Faatasi ai ma le faateleina o ituaiga eseese, e masani foi ona faaaoga i le eliina, faamamaina faavae, vili hydrogeological, coring, tunneling i le matagaluega o felauaiga nofoaafi ma vili vili i lalo o le eleele.
