Whakaahuatanga Hua

Te pane hurihuri API rarawe mō te taputapu keri hinu kei roto i te taonga me te utu whakaheke mai i te wheketere Haina
IADC: Ko te 215 mō ngā hanganga pakeke waenga ki waenga me te kaha pēhi teitei. He mata porotaka hiri niho rino me te tiaki ine.
Ko ngā taipitopito o te whenua e pā ana ki ngā toka ngohengohe, kāore i te paparanga, kāore i te pai te kiato, tae atu ki ngā kōhatu onepu, ngā kohatu uku mārō, ngā uku kāore i te pai te kiato, te gypsum, ngā tote me ngā waro mārō.
He taputapu keri nui te mata tricone. Ko te mahi a te mata roera tricone he pā, he kuru, he kutikuti, he amo hoki i te papa toka ina huri ngā koeko roera. Nō reira, ka taea e te mata roera tricone te urutau ki ngā papa ngohengohe, waenga me te mārō.

Ko te 12 1/4" he 311.1mm, e kiia ana e mātou ko te 311mm. He rahi noa tēnei mō te kaupapa keri toka puna hinu. Ka whakamahia tēnei mata keri rahi mō ngā taputapu keri iti te kaha, ā, he whānui te whakamahinga puta noa i te ao.
He mea nui kia whiriwhiria te rahi me te momo tika o te mata tricone i te wā e keri ana. He rerekē te pakeke o ngā toka, he ngohengohe, he waenga, he pakeke, he tino pakeke rānei. Kāore te pakeke e rerekē ahakoa he momo toka kotahi, pērā i te kōhatu papatahi, te kirikiri me te onepū, he kōhatu papatahi ngohengohe, he kōhatu papatahi waenga me te kōhatu papatahi pakeke, he kōhatu papatahi waenga me te onepū pakeke.
Nō reira, tēnā whakamōhio mai ki a mātou i ngā āhuatanga katoa, pērā i te pakeke o te toka, te momo taputapu keri, te ROP (tere hurihuri), te WOB (Taumaha o te mata) me te toque. He āwhina nui ki te mōhio ki ngā mata e tika ana mēnā ka taea e koe te whakamōhio mai ki a mātou mō te keri poka poutū, te keri whakapae rānei, te keri poka hinu, te keri kore-keri rānei, te whakatō pou turanga rānei.
