Mawu Oyamba
Pobowola mpweya, ngati mapangidwe ali ovuta kwambiri kuti alowe ndi kukoka pang'ono, nyundo ya DTH imagwiritsidwa ntchito.Chida ichi chinapangidwira makampani amigodi ndi miyala.Mapeto a 'bizinesi' - batani la batani - ali ndi 'mabatani' a hemispherical tungsten carbide, komanso ma tchanelo omangidwira kuti mpweya woponderezedwa udutse.Pamene nyundo ikanikizidwa pansi, pang'onopang'ono amakakamizika kuchitapo kanthu (monga pobowola msewu) ndi mpweya woponderezedwa womwe umalowetsedwa pansi pa mapaipi obowola.Kenako, chidacho chikazunguliridwa mu dzenje, mabataniwo amagwira ntchito patsinde lonse la borehole.Nyundo zambiri zimazungulira mothamanga 20 mpaka 30 pa mphindi imodzi, ndipo nkhonya zimatha kumenyedwa mpaka 4000 pa mphindi imodzi.Zinyalala nthawi zambiri zimatulutsidwa (kuwombedwa) kuchokera mdzenje kumapeto kwa chitoliro chilichonse.Nyundo za DTH zimakhala zogwira mtima kwambiri pakupanga miyala yolimba monga miyala yamchere kapena basalts;zofewa, zokongoletsedwa bwino zimakonda kutseka ma ducts a mpweya kapena kupanikizana ma slide a pistoni.
Komabe, nyundo za DTH ndizotsika mtengo kwambiri chifukwa chake zimatchuka kwambiri ndi obowola malonda.
