Top hammer drill: for drilling diameter 32 mm – 115 mm
Small diameter holes with a depth of less than 17 meters, non broken rock formations
DTH drill: for drilling diameter 90 mm – 178 mm
Medium / deep holes, in medium to hard rock, major diameter holes for geological conditions with broken rock formations
Rotary drill: for drilling diameter of 178 mm – 405 mm
Medium soft rock formation, generally used in large open-pit mines
| Rock condition | Rock structure usually developed fractures, cavity, interlayer, mud layer, etc; Need to rig multi-angle hole, foot hole and other functions to deal with slope, foundation or triangle ore body; |
| Drill tools consumption | Top hammer drill is easy to jam when drilling, break drill rods, drilling tool consumption is large; DTH drill has much less jam when drilling, drilling tool consumption is small; |
| Comprehensive drilling rate Hole forming efficiency | Top hammer drill is easy to jam when drilling, start drilling fast but the deeper the hole is, the slower the drilling speed is, causes low comprehensive drilling speed and low hole forming efficiency; DTH drill with stable drilling speed, and higher hole forming efficiency; |
| Noise & TCO | Top hammer drill causes higher noise, and total cost of ownership is higher; DTH drill with lower noise, environment friendly, and 30% lower total cost of ownership than top hammer. |
