How to evaluate the drilling efficiency of a percussive drill rig?

Evaluation of drilling efficiency by coupling v and e The drilling rate and the specific energy are two indexes to evaluate the drilling efficiency. The optimal drilling efficiency of the percussive drill rig corresponds to the maximum drilling rate and the minimum specific energy.

How can drilling efficiency be reduced?

Drilling efficiency largely depends on the rate of penetration, which affects power consumption and bit life. The operating cost can be reduced significantly by selecting both the most suitable bit type and the most efficient operating conditions.

What is specific energy in rock drilling?

This definition considers specific energy to be an intrinsic property of the rock and the parameters of breakage mechanism are negligible. This implies that, in the case of rock drilling, specific energy is independent of shape of the drill bit, drill type, and methods of cutting removal, and depends only on rock properties.

Why do drilling operators need a new index based on rock properties?

However, drilling operators always change drilling parameters to achieve higher drilling efficiency. Hence, a new index that is only related to rock properties and can be successfully applied under different drilling conditions should be developed to define rock properties.

What is a defined drilling rate?
