Dual Mud And Air Drilling Technology

The biggest advantage of the DL-280 Mud/Air Drilling Rig is its multifunctional drilling capability.

The machine supports two drilling methods:

Air DTH Drilling Mode

Air drilling uses compressed air to power a down-the-hole hammer for efficient rock breaking.

Advantages:

High drilling speed
Strong impact force
Excellent hard rock penetration
Efficient removal of drilling debris
Improved drilling productivity

This mode is suitable for:

Granite
Limestone
Hard rock formations
Mining exploration holes
Mud Circulation Drilling Mode

Mud drilling uses drilling fluid circulation to stabilize boreholes and remove cuttings.

Advantages:

Better borehole stability
Suitable for soft formations
Effective debris transportation
Reduced hole collapse risk

This mode is ideal for:

Clay layers
Sand formations
Gravel formations
Unstable geological conditions
