Subsurface mining involves digging tunnels or shafts underground to access mineral deposits. Once the ore is reached, it is extracted by drilling, blasting, and removing the material through the tunnels or shafts. This method is used to extract resources such as coal, diamonds, and metals that are located deep underground.

What is subsurface mining?
Subsurface mining is a method used to extract minerals and ores that are located deep underground. It involves creating tunnels and shafts to access the deposits and extract the resources. This method is often used when the mineral deposits are too deep to be reached with surface mining techniques.
Disadvantage of subsurface mining?
A disadvantage of subsurface mining is the risk of cave-ins and collapses, which can result in serious injuries or fatalities to miners. Additionally, subsurface mining can lead to environmental damage through the disruption of ecosystems and contamination of groundwater. The process can also be costly and require extensive monitoring and regulation to ensure safety and minimize negative impacts.
What is the infiltration of water from the surface to the subsurface?
The infiltration of water from the surface to the subsurface refers to the process by which water seeps through the soil and enters underground aquifers or water tables. This process is influenced by factors such as soil composition, vegetation cover, and rainfall intensity. Infiltration plays a crucial role in replenishing groundwater supplies and sustaining hydrosystems.
What is natural subsurface irrigation and artificial subsurface irrigation?
Natural subsurface irrigation refers to the process where water seeps or flows underground to irrigate plants, occurring naturally without human intervention. Artificial subsurface irrigation involves human-controlled methods such as buried pipes or tubes to deliver water below the soil surface to provide moisture to plant roots.
What mining technique is less harmful to the environment surface or subsurface mining?
Subsurface mining is generally considered less harmful to the environment compared to surface mining. Subsurface mining causes less land disturbance and produces less waste material on the surface. However, both mining techniques can have environmental impacts if not properly managed.
