6 FAQs about [Subaru hydraulic rock drill parameter table]

How to determine the input parameters of the rock drilling model?

The conventional rock mechanics tests (UCS test, BTS test and triaxial compression test) were conducted to obtain the input parameters of the rock drilling model, listed in Table 1. The establishment of the rock drilling model and the validation of the numerical simulations in terms of mechanical responses and failure modes

What parameters should be analysed for rock drilling tests?

For most investigations of rock drilling tests, two critical parameters of drilling responses should be analysed, including the thrust force and torque.

What are the characteristic parameters of rock drilling responses?

The average thrust force and torque were selected as characteristic parameters of rock drilling responses in this study for validation purposes. Then, the numerical simulation was performed for three types of rocks, and the results were compared with the experimental data.

Do different rock parameters affect the mechanical response curves of rock drilling tests?

The effects of different rock parameters on the mechanical response curves of rock drilling tests were investigated based on the verification of the drilling model above.

What are drilling parameters?

Drilling parameters play a large role in helping drillers achieve superior drilling performance and long equipment life. They are basic recommendations that help guide a driller avoid burning core bits or damaging other drilling equipment, and help achieve a good rate of penetration and core recovery.

What are the testing process and drilling parameter determination?

The testing process and drilling parameter determination are consistent with that of the third test set as described in Sections 5 Third test set and results for drilling rock with constant rotation speed, 6 Third test setup and result for drilling rock with constant thrust force. The test results are summarized in Table 5.
