6.1. Composition of Production Cycle

Try these first

1. 1.

   What is the main disadvantage of back-track loading?

   Hint

   Think about how the pusher moves after loading.

2. 2.

   Which loading method is most suitable for long narrow cuts?

   Hint

   Consider the method that minimizes return time.

3. 3.

   What is the primary disadvantage of the back-track loading method?

   • It requires more manpower
   • It is the fastest method
   • It adds additional return time
   • It is too complicated

   Hint

   Consider why it is noted as the slowest method.

4. 4.

   True or False: Chain loading is the preferred method for loading when there are fill areas in both directions.

   • True
   • False

   Hint

   Think about which method is ideal for opposite fill areas.

5. 5.

   Calculate the total cycle time for a project where the pusher cycle time is 4 minutes and the scraper load time is 10 minutes. How can optimizing this cycle time affect project costs?

   Hint

   Use the given formula and consider the effect of reducing the cycle time on productivity.

6. 6.

   Discuss how switching from back-track loading method to chain loading impacts the productivity of an ongoing project. What factors should be considered?

   Hint

   Think about the layout and operational adjustments required when changing methods.
