    Rock chips mechanically freed from the parent rock by the drilling action of the bit are generally held in place by overbearing pressures. These pressures must be overcome either by hydraulic action or pressures. These pressures must be overcome either by hydraulic action or by mechanical regrinding before the chip may be removed.

    The stress wave energy generated during the impact process is propagated into the rock along the direction of the bit–rock interface, causing damage to the rock near the impact area, which is conducive to improving the rock-breaking efficiency (Saksala et al., 2018, Franca, 2011). Many studies have been conducted to make percussion drilling technology effective for oil and gas drilling.
