The mechanical drilling rock breaking technology mainly relies on the impact and scraping of the drill bit on the rock to break the rock. The method has a long history, mature technology and wide application, but the rock breaking efficiency is low, making it difficult to achieve efficient rock breaking in deep, ultra-deep and complex difficult to drill formations.
