Utangulizi
DTH Nyundo ya Nyuma BH140 BH170 BH190 BH240 ya kuchimba visima vya maji, uchimbaji madinikuchimba visima, ambayo husaidia bure DTH Nyundo na kutoboa mabomba ambayo yamejifunga kwenye shimo la kuchimba.Inatumika sana katika uchimbaji hewa wa DTH.
Nyundo ya Nyuma ni chombo kinachoweza kuhifadhi na kufunika tena kamba ya kuchimba visima iliyokwama kwenye shimo, inaweza kuwekwa kwa urahisi katika kiungio cha bomba kinachofaa kati ya kisu cha kuchimba visima na kichwa cha kuzungusha ili kutoa mchanganyiko mzuri wa upigaji nyundo wa nyuma na mtetemo. fungua kamba za kuchimba visima zilizokwama.
Nyundo za nyuma za DTH hutumiwa kushughulika na kuchimba visima vilivyokwama, kugonga hadi kutatua shida ya kuchimba visima.
