6′ ubungakanani phantsi umngxuma dth isando kunye nentwana ixabiso umzi-mveliso ezithengiswayo Umfanekiso Featured

Inkcazelo emfutshane:

Isando se-DTH luhlobo lwezixhobo zokomba zamatye, umahluko phakathi kwabanye kukwixesha lenkqubo yokomba isando sihlala sisezantsi kumngxuma, sichaphazele ilitye ngesuntswana kwihamile ngqo.Umoya woxinzelelo oluphezulu ungena kwihamile ngombhobho wokubhoboza, emva koko uphume kwimingxuma yokubhoboza, umoya wokukhupha usetyenziselwa ukuvuthela iziqwenga ukusuka ezantsi komngxuma.Amandla ajikelezayo asebenza kwisando se-DTH avela kwi-motor ejikelezayo kwi-drill rig, amandla okutsala avela kwisixhobo sokutyisa kunye nokudlulisa amandla kwihamile ngombhobho wokubhoboza.

Iithegi zeMveliso

Impembelelo ye-DTH yinxalenye ye-drilling rig ephantsi, sisixhobo esisebenzayo sombhobho wokubhoboza.Impembelelo yahlulahlulwe ibe nguxinzelelo lomoya ophantsi, uxinzelelo oluphakathi kunye nefuthe loxinzelelo lomoya oluphezulu.Isetyenziswa ngokubanzi kwisinyithi, amalahle, imichiza, imigodi kunye nokugcinwa kwamanzi, umbane wamanzi, uhola wendlela, uloliwe, ukhuselo lwesizwe, ulwakhiwo kunye neminye imingxuma yobunjineli. Ilungele ukusebenza okomileyo kunye nokumanzi kwamanzi e-blasthole, ukusebenza kwayo kuthembekile, ngoko sesona sixhobo sigqwesileyo sokugrumba.
