Isixhobo sokugrumba i-Down-the-hole sisixhobo esisetyenziselwa ukugrumba (ukufaka kumngxuma ogrunjiweyo) kwilitye okanye umaleko womhlaba phambi kokugrumba iprojekthi.
Isetyenziswa kakhulu kwimigodi emikhulu, ephakathi kunye nencinci, umbane wamanzi, uthutho kunye nezinye iiprojekthi zokumba umhlaba kunye namatye kunye nokuqhushumba, iiprojekthi zenkxaso yendlela yendlela yamalahle, imibhobho enzulu yezithuthi zemigodi, njl.
I-drill ephantsi-kwi-hole yenzelwe ngokweempawu zeendlela, umzila kaloliwe, ukugcinwa kwamanzi, umbane wamanzi, ukwakhiwa kwemigodi kunye nezinye iiprojekthi.Iindlela ziphazamisekile ekuqaleni kokwakhiwa, kwaye izixhobo zokunyusa kunye nezokuthutha azikwazi ukuthutha ngokuthe ngqo izixhobo kwindawo yokwakha.Uninzi lwabantu lungena kwisiza kuphela ngokutsala amagxa.Enye yezona zinto zikhaphukhaphu ezantsi emngxunyeni drills, ezinokunciphisa ubunzima bomkhosi ukuya kumlinganiselo omkhulu, kodwa usenakho ukuhlangabezana neemfuno zabasebenzisi bokwemba imingxuma emikhulu.Ikwafanelekile kwi-anchoring ye-slope, i-patios yokumba kunye nemingxuma yokukhupha umoya, njl., kwaye ingasetyenziselwa imisebenzi yemigodi ephantsi komhlaba.Ngenxa yokuba lo matshini awunawo umsebenzi wokuthintela uqhushumbo, akufuneki usetyenziswe kwimigodi engaphantsi komhlaba enerhasi.
