20.8.3. Mining and Quarrying

Try these first

1. 1.

   What is induced seismicity?

   Hint

   Consider the definition involving human influence on seismic events.

2. 2.

   Describe the process of blasting in mining.

   Hint

   Think about how energy is transferred in blasting.

3. 3.

   What is the main cause of induced seismicity in mining?

   • Natural tectonic movements
   • Blasting operations
   • Earthquake swarms

   Hint

   Think about how miners break rocks.

4. 4.

   True or False: Mine collapses can cause small earthquakes.

   • True
   • False

   Hint

   Consider the effects of sudden structural failure.

5. 5.

   Examine a scenario where a new quarry is being established near a fault line. What precautions should be taken to mitigate the risk of induced seismicity?

   Hint

   Consider both engineering practices and geological assessments.

6. 6.

   A recent study finds that a nearby community experiences increased seismic activity correlating with the start of a mining operation. How would you assess if this activity is induced?

   Hint

   Link your findings with patterns observed in induced seismicity research.
