Nov 06, 2019 · This paper presents a simulation model to predict the percussive drilling performance of a downthehole (DTH) hammer. First, the pneumatic dynamic model of the DTH hammer is developed considering mass flow rate relations representing orifice opening areas of the air tube, the piston, and the bit flushing channels. Next, the performance of the DTH .
