Study the stone cutting process of the drilling installed on rotary drilling machine

Abstract

The rotary hammer rock drill is used for blast hole drilling in underground construction and mining. This equipment operates based on the principle of top percussion drilling, generating impact force and rotational torque to drive the drilling process. During drilling, the hammer drill creates impact force and rotational torque for the drill bit, enabling effective penetration through soil and rock. This complex cutting process, primarily utilized in the rock drilling and mineral exploration industries, involves a drill bit mounted on a rotary drill. This article examines the mechanics of soil and rock cutting with a rotary drill-mounte bit.

Keywords: Drill bit; torque; axial force; cutting tool
