General Sumo:
ODEX (pfupi ye "Overburden Drilling Excentric") inonziwo Stratex, Tubex kana ODS. Iyo inogadziriswa yemhepo-inotenderera DTH sando. Iyo ine swing-out eccentric bit kuti idzore pazasi pecasing. Uye bhiti rekurova rine zvikamu zviviri zvakagadziriswa matipi: a concentric pilot bit, uye kuseri kwaro kune eccentric reamer bit inosuduruka kukudza chibhorani dhayamita panguva yekuchera. Mushure meiyo eccentric bit igwara rekushandisa rinobata yakakosha yemukati mafudzi casing shangu pazasi peODEX casing. Iyo ODEX saka inodhonzwa pasi netambo yekuboora sezvo gomba riri mberi. Zvichekwa zvinoputika nemukana we annulus pakati pechishandiso chegwara uye shangu yekusungirira kune inotenderera ichivaendesa pasi kana kumuunganidzi wemuenzaniso.
ODEX masisitimu ndiwo akanyanya kugadzirisa ehupfumi ekuchera mabheji muavhareji yepasi mamiriro. Ivo vanofarirwa zvakanyanya nevanochera makondirakiti ekuchera mumatsime emvura, geothermal matsime, yepakati mini-mhando grouting gomba rekuvaka, dhamu uye chiteshi chengarava, uye isina kudzika micro-piling basa. Nekuda kwebapiro reungwaru rekudzorerazve, chidimbu chinodzoserwa uye chinogona kushandiswa zvakare. ODEX yakanakira maburi mapfupi mune homogenous overburden, nekuda kwezvakatanhamara sechimiro chakareruka, mashandiro ari nyore, maturusi ekuchera anodzoreredzwa, hupenyu hurefu hwebasa uye mhando yakanaka. Kuchera maitiro eODEX masisitimu akanyanya kufanana neyeDTH sando yekuchera nzira, senge:
Kukurumidza kubviswa kwekucheka;
Kupinda kwepamusoro kwepamusoro, kunyanya mukugadzirisa dombo rinopesana (e.g. basalt);
Ivhu riri nyore uye sampling yemvura yepasi panguva yekuchera;
Zvinogoneka kuyera fungidziro yegoho pakudzika kwakasarudzwa mukuumbwa;
Yakanakira mune isina kubatanidzwa maumbirwo ane njodzi yakakura yecaving (ichi chingangodaro chinonyanya kukosha).
PLATO ine mhando dzeODEX dzinotangira paODEX90 kusvika ODEX280, dzakagadzirwa nemashangi ezvakawanda zvesando dzeDTH dziripo kubva pa3” kusvika pagumi”. Iwo ese anosanganisira Chishandiso cheKutungamira, Casing Shoe, Eccentric Reamer, Pilot Bit, Runotungamira, uye Kukiya Kits.
