Study on the abrasion property of the anvil inside a hydraulic DTH hammer fitted with horizontal oriented sliders

Jiang-fu He, Qi-lei Yin, Kun Yin

Hydraulic hammers have been extensively applied to horizontal directional well drilling in hard rock formations. However, the service life of a hydraulic hammer is still unsatisfactory due to the heavy wear or abrasion of the horizontal…
