Subsurface mining is used extensively in the extraction of:

A. Coal, phosphate, diamonds, gold
B. Oil sands
C. Coltan
D. Limestone, natural gas, peat
E. Organic soils for landscaping

Answer :

Final answer:

Subsurface mining is proficiently used for extracting deep resources like coal, diamonds, and gold. This method includes shaft and in-situ mining, which access localized mineral deposits while minimizing surface disturbance. Notably, subsurface mining is crucial for deep ore deposits inaccessible by surface methods.


Explanation:

Subsurface Mining Overview

Subsurface mining is a method used extensively for extracting resources that are located deep underground. This mining technique includes methods such as shaft mining and in-situ mining, which are especially useful for accessing localized or concentrated minerals. Some of the key resources extracted using subsurface mining are:

  • Coal
  • Diamonds
  • Gold

These materials often require deep vertical shafts and horizontal tunnels to access the ore body efficiently. For instance, the Witwatersrand basin in South Africa is famous for its deep gold mines, where the extracted gold is obtained from depths exceeding 3,500 meters. This method is preferred in cases where the ore is too deep for surface mining, as it generates less surface disturbance and typically results in fewer waste materials than surface mining.
