What are the advantages of surface mining of coal compared to underground mining?

Compared with underground mining, surface mining is much more efficient. Unfortunately, this economy comes with a strict environmental cost because the surface environment is destroyed and polluted during the mining process.

Which is one advantage surface coal mining has over other mining techniques?

Surface coal mines must undergo reclamation once they are closed; this reduces the environmental damage of mining but does not eliminate it. Human society runs on energy, and coal continues to be a major reliable energy resource.

What is subsurface mining process?

Subsurface mining is a mining method in which soil and rocks are removed to reach underlying coal or minerals. It is used to mine ore deposits that are 50 m or more beneath Earth’s surface. Room-and-pillar mining is a common method of subsurface mining.

Which type of mining surface or subsurface has a greater impact on the environment?

Surface mines are the most damaging to the environment, because they cause the greatest amount of change to the land. Surface mines involve the removal of earth to extract minerals, often leaving a gaping hole behind.

What is the difference between subsurface and strip mining?

In STRIP MINING, a type of surface mining, a trench is dug to extract the minerals. SUBSURFACE MINING is the extraction of mineral and energy resources from deep underground deposits.

What is a surface hazard resulting from subsurface mining quizlet?

Mining of the surface can result in severe erosion by wind and water. It can pollute streams with sediment. It results in toxic wastes percolating down to groundwater. … It requires enormous amounts of energy, causes land disturbance and erosion, causes air and water pollution, and produces solid and hazardous wastes.
