22.12.1. Key Performance Indicators (KPIs)

Try these first

1. 1.

   What does ROP stand for?

   Hint

   Think about a drilling speed measurement.

2. 2.

   Define Volume per Cycle.

   Hint

   Focus on productivity in excavation.

3. 3.

   What does the Rate of Penetration (ROP) measure?

   • Speed of drilling
   • Volume of material
   • Fuel consumption

   Hint

   Consider what speed could relate to in drilling.

4. 4.

   True or False: A lower Error Rate indicates better precision in drilling.

   • True
   • False

   Hint

   Think about what it means to stay on target.

5. 5.

   An autonomous drilling machine operates with an ROP of 15 meters/hour. Calculate how much distance it will cover in a 4-hour operation.

   Hint

   Use the formula for distance calculation based on speed and time.

6. 6.

   If an excavation machine worked for 8 hours and moved 120 cubic meters of material, determine its VPC.

   Hint

   Think about cycles in determining efficiency.
