Underground mining create cavities in the subsurface, with time these cavities get enlarge and the support which are left for the roof are deteriorate and result into a large void, which make instability in underground mining. The mining subsidence reduces the capacity of the soil and increase the soil infiltration depth and evaporation.

Pros of Subsurface Mining. Resource Accessibility: Subsurface mining is essential for extracting minerals and ores that are deep below the Earth's surface. Without this method, certain resources like gold, diamonds, and zinc would remain inaccessible and unexploited, depriving economies of vital raw materials.

As a general rule surface mining is more cost effective than subsurface mining. The most common surface mining technique is open-pit mining (Figure 1), where a commodity is extracted via an open pit in the ground. This is an extremely cost effect way of removing a resource because large quantities can be removed with minimal effort.

Subsurface Mining. When mineral ores are too deep to get at with the surface mining techniques, subsurface mining methods are used instead. An advantage of subsurface mining is that it disturbs much less land than surface mining. In fact, it disturbs less than one-tenth the amount of land as surface mining.
