### Explanation:

#### Tragedy Degree: 6
- The story contains a significant tragic element—an explosion in the mine—that results in panic and injury and jeopardizes the town's primary source of livelihood. 
- While the town suffers a considerable setback, the event is not overwhelmingly tragic as no fatalities are mentioned, and there is a hopeful resolution implying recovery and growth.
- The emotional impact is moderate to strong due to the depiction of the miners' peril and the entire town's economic plight.

#### Comedy Degree: 3
- The story has very few if any comedic elements, and it does not focus on humor or light-hearted situations.
- The ending is not entirely happy or comedic but is more positive and hopeful, focusing on the town's unity and recovery efforts.
- The tone remains primarily serious throughout with moments of inspiration rather than comedy.
