Folasaga Lautele:
O lo'o i ai le PLATO i le tulaga e ofoina atu le tele o pusi fa'au'u DTH fa'atasi ai ma ta'ita'i uma o fa'ata'ita'iga samala a le au gaosi o lo'o i ai nei e fa'afetaui i le tele o talosaga vili. O matou DTH drill bits uma foi o le CAD ua mamanuina, CNC na gaosia mo le tino atoatoa, ma le tele o le vevela e faʻaleleia ai le maaa, faʻapipiʻiina i luga mo le vaivai, o mea uma e faʻalautele ai le ola o oloa mo le maualuga o laei ma faʻatinoga i le faigata o le viliina. tulaga. E le gata i lea, o nei pa'u uma e faia mai i u'amea u'amea maualuga ma fa'apipi'iina i fa'utuaga tungsten carbide sili ona lelei mo le maualuga o le sao.
O le PLATO e masani ona i ai ni mamanu autu e tolu: Mata Fa'afolafola, Convex ma Concave. O nei mea ua mamanuina mo faʻaoga faʻapitoa mo ituaiga papa uma, maʻaʻa ma tulaga:
| Ituaiga Mata | Omiga talafeagai | Talosaga | Faiga masani | Pu sa'o | Tulaga Fa'asa |
| Mafolafola Luma | Maualuga | Malosi tele ma abrasive | Granite, limestone malo, basalt | Talafeagai | Lelei |
| Fa'apa'u | Maulalo i le feololo | E feololo i le malo, itiiti le abrasive, gau | Granite, limestone malo, basalt | Lelei tele | Talafeagai |
| Fa'amau | Maulalo i le feololo | Malu i le feololo malō, e le fa'asa | Limestone, limestone malo, shale | averesi | Lelei |
Filifilia o Pisi Sa'o
O le ola tautua bit ma le fua o le penetration o tulaga sili ona taua i le filifilia o le bit sa'o mo se talosaga faapitoa. I le tele o tulaga, o le taulaiga o loʻo i luga o le gaosiga, o lea e sili atu le lelei o vaega o le tipiina vave, ina ia mautinoa o loʻo tipi mama, ma le itiiti ifo o le toe tuʻimomomoina.
O le DTH bit o le meafaigaluega e tipiina ai maa, ma e a'afia i le mamafa tele mai le piston e taia fa'apea fo'i ma le tipi abrasive o lo'o pasia le biti i le saoasaoa maualuga. A filifilia le mea sa'o mo le fa'atinoga sili ona lelei e tatau ona e fa'apaleni le fa'asaga i le ola. I nisi taimi e mafai ona e ositaulagaina ma le manuia le ola mo le ulu, manatua le tulafono o le lima matua o loʻo taʻu mai ai o le 10% o le faʻateleina o le ulu e aofia ai le itiiti ifo i le 20% le leiloa i le ola.
