Intangiriro
DTH Inyundo Inyundo BH140 BH170 BH190 BH240 yo gucukura neza, ubucukuzi bw'amabuye y'agacirogucukura, bifasha kubuntu DTH Nyundo nubusa imiyoboro yacometse mu mwobo.Ikoreshwa cyane mugucukura ikirere DTH.
Inyundo yinyuma nigikoresho gishobora kuzigama no gupfundikira umugozi wimyitozo wometse mu mwobo, urashobora gushyirwaho byoroshye muguhuza umuyoboro ubereye hagati yingoboka ya drillage n'umutwe uzunguruka kugirango utange uburyo bwiza bwo guhuza inyundo ninyuma hamwe kurekura imigozi y'imyitozo.
Inyundo yinyuma ya DTH ikoreshwa mugukemura imyitozo yafashwe, gukubitwa kugirango ikemure ikibazo cyimyitozo.
