Answer :

Final answer:

Subsurface mining presents both benefits and drawbacks. It allows for the extraction of valuable resources with less surface disruption but poses risks such as environmental degradation and health hazards. Understanding these aspects can inform better practices and policies in resource extraction.


Explanation:

Positive and Negative Aspects of Subsurface Mining


Subsurface mining is a method used to extract minerals and resources located beneath the earth's surface. While it has its benefits, it also comes with significant drawbacks.


Positive Aspects



  • Resource Extraction: Subsurface mining allows for the extraction of valuable minerals like coal, gold, and diamonds that are not accessible through surface mining.

  • Less Surface Impact: This method often leads to less disruption of the surface environment compared to surface mining, preserving ecosystems and landscapes.

  • Safety for Workers: In some cases, subsurface mining can provide safer working conditions compared to surface mining, as less exposure to elements like weather and wildlife occurs.


Negative Aspects



  • Environmental Degradation: Subsurface mining can lead to soil and water contamination from the chemicals used in the process, affecting local ecosystems and drinking water supplies.

  • Health Risks: Miners face health risks such as exposure to harmful dust and minerals that can lead to long-term respiratory problems.

  • Subsidence: The collapse of mining tunnels can cause subsidence on the surface, damaging infrastructure and homes.
