Uyilo lwevalvu yehamile ye-DTH lubonelela ngokusebenza okuthembekileyo, ukusetyenziswa komoya okuphantsi, ukugcinwa lula kunye nokwakhiwa kwakhona okunexabiso eliphantsi.Ifoto ngoncedo lweCaterpillar.
Isando se-DTH si-6 intshi ububanzi kwaye yayingowokuqala ukufakwa kumgca wemveliso ye-DTH.Ngokutsho kwenkampani, idizayini yevalve yayo ibonelela ngokusebenza okuthembekileyo, ukusetyenziswa komoya okuphantsi, ukugcinwa lula kunye nokwakhiwa kwakhona kweendleko.Ukongezelela, idizayini yepiston ibonelela ubomi obude kunye nokudluliselwa kwamandla okusebenzayo.
Isando sinokusebenza kunye nenkqubo yomoya ocinezelweyo ukuya kwi-500 psi. Olu xinzelelo olongezelelweyo lwangasemva, oludityaniswe ne-airflow ehambelanayo efunekayo, luvelisa ukubetha okungaphezulu ngomzuzu, okubangelwa kumazinga okungena ngokukhawuleza.
Kwakhona inikezela ngoqheliso lokugrumba ezantsi-umngxuma.Iintwana ngoku zifumaneka kuqwalaselo oluninzi olwahlukeneyo (i-intshi ezi-6.75) kwiinguqulelo ezisemgangathweni nezinzima ukutshatisa amasuntswana kwiipropati zamatye kunye neemfuno zomsebenzi.
Izinketho ze-Bit ziquka iintlobo ezahlukeneyo zeemilo ze-carbide (i-spherical, i-ballistic) kunye neemilo zobuso (i-concave, i-flat, i-convex), kwaye ilungiselelwe ukuxhathisa ukunxiba okuphezulu kunye nokuphucula i-rock chipping.Isakhiwo esinobudlova, esihlala ixesha elide esidityaniswe kunye neengqungquthela eziphezulu ze-DTH. bonelela ngokungena okukhethekileyo.
