6′ usayizi phansi kwesando se-dth kanye nenani lefekthri elincane elithengiswayo Isithombe esifakiwe

Incazelo emfushane:

Isando se-DTH siwuhlobo lwamathuluzi okumba amatshe womoya, umehluko kwabanye ungaphakathi kwenqubo yokumba isando sihlale phansi embobeni, sithinte idwala kancane kusuka esando ngokuqondile.Umoya onengcindezi ephezulu ungena esando ngepayipi lokubhoboza, bese uphuma ezingxenyeni zokubhoboza, kusetshenziswa umoya okhipha umoya ukuze uqhumise ama-cuttings asuka phansi embobeni.Amandla ajikelezayo asebenza kwisando se-DTH avela kumotho ezungezayo emshinini wokubhoboza, amandla okudonsa avela kudivayisi ephakelayo futhi adlulise amandla awashaye ngepayipi lokubhoboza.

Umlayezo I-imeyili

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-DTH impactor iyingxenye yerigi yokumba imbobo ephansi, iyisisetshenziswa esisebenzayo se-down-the-hole rig yokumba.I- impactor ihlukaniswe yaba yi-low wind pressure , i-medium pressure kanye ne-high wind pressure impactor.Isetshenziswa kabanzi kwezensimbi, amalahle, amakhemikhali, izimayini nokongiwa kwamanzi, ugesi wamanzi, umgwaqo onguthelawayeka, ujantshi, ukuvikela izwe, ukwakhiwa kanye neminye imigodi yobunjiniyela. ukwenza ukusebenza.Kufanele ukusebenza okomile nokumanzi kwamanzi e-blasthole,Ukusebenza kwawo kunokwethenjelwa,Ngakho iyidivayisi engcono kakhulu yokumba imbobo.
