A down-the-hole drill rig, inozivikanwawo seDTH drill rig, muchina une simba unoshandiswa mumaindasitiri akasiyana ekuchera makomba pasi.Inowanzoshandiswa mumigodhi, kuvaka, uye kuongorora mafuta uye gasi.Ichi chinyorwa chichatsanangura kuti chidhiraivho chepasi-gomba chinoshanda sei uye nemisimboti yayo.
Nheyo yekushanda ye-down-the-hole drill rig inosanganisira kusanganiswa kwemaitiro ekuchera uye midziyo.Iyo drill rig yakashongedzerwa nesando, iyo yakabatana kusvika kumagumo etambo yekuchera.Sando inofambiswa nemhepo yakamanikidzwa kana hydraulic power uye ine piston inorova dhiri.Chibooreso chine basa rekupwanya dombo kana pasi uye kugadzira gomba.
Kana chibooreso chiri kushanda, tambo yekubooresa inotenderedzwa nesimba regiyo, senge injini kana mota.Sezvo tambo yekubooresa ichitenderera, sando nechibooreso zvinofamba zvichikwira nekudzika, zvichigadzira kurova.Sando inorova chibooreso chine frequency nechisimba chakakwirira, ichichibvumira kupinda pasi kana padombo.
Chibooreso chinoshandiswa mudhiri repasi-the-gomba rakagadzirirwa kuchera zvine hunyanzvi.Yakagadzirwa nemidziyo yakaoma, senge tungsten carbide, kuti imirire iyo yakakwira mhedzisiro uye abrasion panguva yekuchera.Iyo drill bit inogona kunge iine maumbirwo akasiyana uye saizi zvichienderana nezvinodiwa zvekuchera.
Kuve nechokwadi chekuchera zvakanaka, mvura kana mvura yekuchera inowanzoshandiswa panguva yekuchera.Mvura yekuchera inobatsira kutonhora pasi pechibhorani, kubvisa zvakachekwa, uye kupa mafuta.Inobatsirawo kudzikamisa gomba uye kudzivirira kudonha.
Chibooreso chepasi-the-hole chinowanzoiswa pane chinokambaira kana rori kuti zvifambe zviri nyore.Inoshandiswa nevashandisi vane hunyanzvi vanodzora maparamendi ekuchera, senge kutenderera kumhanya, kusando frequency, uye kudzika kwekuchera.Advanced drill rigs inogonawo kunge iine otomatiki maficha uye zvidzoreso zvekombuta zvekunatsiridza humbowo uye kugona.
Mukupedzisa, pasi-the-hole drill rig inoshanda nekubatanidza nzira dzekuchera nemidziyo.Sando, inosundwa nemhepo yakamanikidzwa kana simba remvura, inorova chibooreso chine frequency yakakura uye nesimba rekupwanya pasi kana dombo.Chibooreso, chakagadzirwa nezvinhu zvakaomarara, chinopinda pasi apo tambo yokubooresa ichitenderera.Mvura kana mvura yekuchera inoshandiswa kuwedzera basa rekuchera.Nekugona kwayo kwakasimba uye kunyatso kudzora, iyo pasi-the-gomba drill rig chinhu chakakosha mumaindasitiri akasiyana.
