6 FAQs about [Rock drill usage experiment report]

Do drill operating parameters affect rock strength during drilling?

From the above-discussed literature, it was observed that the variation of drilling parameters such as thrust and torque is significant during drilling of different rocks. Therefore, the drill operating parameters can be possible variables to characterize the rock strength during the drilling.

Is a drilling experiment platform capable of real-time collection of drilling parameters?

To further substantiate the reasoning presented previously, this study developed a drilling experiment platform that is capable of real-time collection of drilling parameters. This platform is designed to accommodate various parameter sensors, enabling the execution of drilling experiments on different rock specimens.

How is rock breaking achieved in a drilling process?

1. During the drilling process, rock-breaking is primarily achieved through the vertical thrust of the drill rod advancing the drill bit and the torque applied in the horizontal direction rotating the bit.
