Keywords: Downhole drill rig parameters, drilling efficiency, air compressor selection, impactor matching, hard rock drilling
The efficiency of a downhole drill rig is not solely determined by its power; the matching of impactor frequency, airflow, and drilling pressure is crucial. Insufficient airflow from the air compressor prevents timely removal of rock cuttings, leading to repeated crushing and drill bit wear. For example, in mining blast hole drilling, matching a “high-airflow air compressor + high-frequency impactor” can increase drilling speed by 40%.
But is a higher impactor frequency always better?
Follow us, and in our next issue, we will analyze the risk of drill rod fatigue fracture under high-frequency impact and share preventative solutions…
