Pasi pegomba (DTH) mabhiti ekuchera inzira yekucheka-chinja inoshandura mashandiro ekuchera mumigodhi neindasitiri yekuvaka.Aya mabhii anochinja-chinja, anoshanda-pamusoro, anozivikanwawo senyundo, anoshandisa sando inofambiswa nemhepo iri pamuromo webhiti.Iyi sando inoburitsa kurova kune simba kutambo yekuboorera, ichiibvumira kupinda kunyange nematombo akaomarara.
Mukana wekutanga weDTH yekuchera mabhiti ndeyekuwedzera kwavo kwekupinda mwero, kunyanya mumamiriro akaoma edombo.Kusiyana nemaitiro echinyakare, ayo anovimba nekudhirowa kwechitenderedzwa kana percussive, DTH drilling bits anoshandisa musanganiswa wezvose zviri zviviri, zvichibvumira kuchera kwakanyanya uye nekukurumidza.Pamusoro pezvo, DTH drilling bits dzakagadzirirwa kuti dzimire dzakaomarara nharaunda dzekuchera, kusanganisira yakakwirira-kudzvanywa uye yakakwirira-tembiricha mamiriro, zvichiita kuti ive yakakodzera kune yakafararira yekushandiswa.
Imwe yemabhenefiti akakosha eDTH yekuchera mabheti ndeyekuita kwavo kwakasiyana-siyana.Inogona kushandiswa kumabasa akasiyana-siyana, anosanganisira kuchera maburi ekuputika, kudhirowa kwekugadzira, kuchera kwekuongorora, uye kunyangwe kuchera pasi pevhu.Izvi zvakasiyana-siyana zvinovaita mhinduro inodhura kune akawanda akasiyana mapurojekiti ekuchera.
Kugadzira mabhiti ekuchera eDTH inzira yakaoma inosanganisira dhizaini nekunyatso gadzira.Iwo mabheti anogadzirwa kubva kumhando yepamusoro simbi uye carbide zvinhu, izvo zvinonyatso kusarudzwa uye kurapwa kuti ive nechokwadi chepamusoro simba uye kusimba.Iwo mabheti anobva anyatsogadzirwa kuti aite zvakatemwa, kuve nechokwadi chakaenderana mhando uye kuita.
Kushandiswa kweDTH kuchera mabheti zvakare kwakatwasuka.Iyo bhiti inongobatanidzwa kune tambo yekuboora uye inodzikiswa mugomba.Kana yave pachinzvimbo, sando yekurova mukati meiyo bit inotangwa, uye maitiro ekuchera anotanga.Mhedzisiro ndeyekuchera kwakanyatso shanda kunogona kubatsira kuchengetedza nguva nemari.
Muchidimbu, DTH yekuchera mabhiti isimba rinokatyamadza rinoshandura indasitiri yekuchera.Nezviyero zvavo zvisingaenzaniswi zvekupinda, kuita zvakasiyana-siyana, uye kusimba, vari kukurumidza kuita mhinduro kune akawanda mapurojekiti ekuchera.Sezvo kudiwa kwezvigadziriso zvekuchera zvine hunyanzvi uye zvisingadhuri zvichiramba zvichikura, DTH mabhiti ekuchera ane chokwadi chekuita basa rinowedzera kukosha mumaindasitiri emigodhi nekuvaka kwemakore anotevera.
