Pneumatic down-the-hole (DTH) hammer drilling, on the one hand, relies on the hammer to deliver impact energy into the formation to break it up (Kondratenko et al., 2016; Chervov, 2020).This is achieved by utilizing the high-pressure gas output from the air compressor to drive the reciprocating movement of the piston inside the hammer, seen in Fig. 1.

The average hammer operator's undamped natural frequency was 3.49 Hz with a damping ratio of 13.7%. Knowledge of the hammer operator dynamics is then utilised to identify the dynamic properties of the supporting structure in an unoccupied state. The results are verified on two fibre-reinforced polymer composite footbridges.
