Geological conditions are the most critical factor in choosing the right air compressor for DTH drilling, as different rock types demand specific air pressure and airflow. Key Formation-Specific Compressor Requirements: Sandy Soil & Soft Sediment: Low pressure+ high airflow; insufficient airflow causes sand settling and stuck drill pipes. Limestone & Sandstone : 15-20 bar pressure; good airflow is critical to clear larger cuttings, with higher airflow recommended to avoid downtime. Granite & Basalt: 20-25 bar pressure; even small pressure drops significantly reduce drilling speed. Gravel & Boulders: Stable, consistent airflow; larger reserve capacity compressors are recommended to prevent borehole cave-ins from sudden pressure drops.
