The crawler-mounted Down-the-Hole (DTH) drill rig for surface blast hole operations is a highly mobile and versatile drilling platform engineered for efficient 360° rotational drilling. Its integrated crawler tracks provide excellent stability and mobility, allowing it to traverse rough and uneven terrain in open-pit mines and quarries with ease.
The defining feature of this rig is its ability to perform 360° continuous rotation. This allows the operator to drill a full circle of blast holes from a single stationary position, eliminating the need for repetitive and time-consuming repositioning of the entire machine. This significantly boosts operational efficiency and allows for the precise execution of complex drilling patterns.

The drilling process utilizes the powerful Down-the-Hole hammer method. A high-energy percussion hammer, located directly behind the drill bit, delivers rapid blows to crush hard rock, while the drill pipe rotates slowly. Compressed air simultaneously powers the hammer and flushes the drill cuttings to the surface, ensuring a clean and efficient boring process. This system is exceptionally effective for drilling consistent-diameter blast holes in abrasive formations like granite and basalt.
In summary, this crawler-mounted, 360° DTH drill rig combines superior mobility with unmatched flexibility. It is an indispensable asset for modern surface mining, ensuring precise, efficient, and rapid drilling for controlled blasting operations.
