6 FAQs about [How to calculate the efficiency of a mining rock drill]

How do you view drilling efficiency?

The traditional ways of viewing drilling efficiency are changing. Drilling is a 3-step process. Operation of the physical drilling rig represents the middle step. Of equal or greater importance in the process are activities and decisions immediately preceding and following rotary rig operation.

How do drilling operators select and evaluate drilling efficiency?

A fundamental task for drilling operators is to select or evaluate drilling efficiency to optimize ROP (Wyering et al., 2017). Relationships between SE and ROP at different rotation speeds were established to evaluate the optimal ROP, as shown in Fig. 8. As shown, the results confirm that more energy input is required to achieve higher ROP.

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.

How to determine the optimal drilling conditions?

The optimal drilling conditions can be obtained by the modified SE model. A index that only related to rock properties was proposed to define the rock strength. Fundamental rock-drilling studies are aimed at optimizing the drilling efficiency by identifying the optimal drilling conditions and rock drillability.

How can drilling companies improve efficiencies and lower costs?

The mining sector continues to look for ways to improve efficiencies and lower costs and drilling companies are following suit. At the end of the day, the best drilling contractors know that it’s all about providing maximum value to the customer. Drilling the meters is only one part of the equation and other metrics provide guidance to total value.

Why is monitoring the drilling process important?

In addition, the monitoring of the drilling processes is a necessary means to evaluate drilling efficiency and stratification conditions. In reality, the drilling process is a relatively good field shear test of soil/rock, in which a large number of parameters related to drilling rigs, such as thrust, rotating speed, and torque, can be measured.
