6 FAQs about [Korean rock drill rotating sleeve parameters]

Does rotary non-percussive drilling cause rock failure?

According to the analysis on the SE values at different drilling conditions in rotary non-percussive drilling, the rock failure before the bit is more related to rotary shear than the axial force. Table 2. Calculation of SE based on different drilling parameters in the field test.

What are the components of a drilling system?

The essential components of a drilling system are the rock drill, feed equipment, drilling rods, bit, supports against the drilling reaction, power source, and cuttings disposal equipment. Different drilling rigs are constructed with various combinations of these elements and other accessories for particular drilling purposes.

How rotary non-percussive drilling machine can be monitored?

To facilitate the monitoring of the drilling process, a new drilling-monitoring system was developed for the conventional rotary non-percussive drilling machine by improving Yue's (2004) innovative drilling process monitoring (DPM) adopted in field drilling.

How rotary drilling rigs are used in open pit mining?

For large-scale open pit mining, it is common to use rotary drilling rigs equipped with three-cone bits or DTHs to drill blastholes. These tools are mechanically compatible with each other, and make it possible to choose the most efficient method according to the particular rock hardness. 2. Construction of Drilling Equipment

What are the optimal rotary drilling conditions?

The optimal rotary drilling conditions in the field can be successfully obtained by the modified SE model first proposed by Teale (1965) that only includes a few control parameters (such as thrust, rotation speed, and bit diameter).

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.
