Q:

What are the disadvantages of mining?

A:

Quick Answer

The major drawback of industrial mining is the damage mining operations cause to the environment. Removal of large areas of topsoil can destroy habitats, and the chemicals used in mining operations can leach into the groundwater and pollute the area. Air pollution and radioactive pollution are other possible downsides.

Another potential danger is geologic instability. In 1980, a salt mine underneath Lake Peigneur in Louisiana collapsed when an oil drilling operation breached part of the mine, and the resulting collapse sucked in barges, vehicles and buildings. Once the lake settled, the entire shoreline and region had been drastically changed by the collapse.

    What is subsurface mining?

    A:

  • Q:

    What is strip mining?

    A:

    Strip mining involves removing the surface layers of earth, called the overburden, in rectangular strips to mine the mineral reserve underneath them. After a strip of ore is mined, another strip is prepared next to it. The waste rock from the overburden of the second strip is used to fill the first one. Typically, coal or other sedimentary rocks that lie near the earth's surface are strip mined.
