While limestone itself doesn''t affect the environment, limestone mining can have a negative impact. On the other hand, the environment can affect limestone by breaking it down. Limestone mining can pollute water and create sinkholes. When limestone dissolves while it''s still in the ground, caves and gullies form, a natural phenomenon known as ...
However, underground limestone mines can be found in the central and eastern United States, especially near cities. In humid climates, limestone dissolves quickly and is carried away by water. This creates caves which can become weak and collapse. Underground mining of limestone can cause a cascading environmental impact.

Limestone mining process. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone. ...
Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
Limestone has many other uses. Powdered limestone is used as a filler in paper, paint, rubber, and plastics. Crushed limestone is used as a filter stone in onsite sewage disposal systems. Powdered limestone is also used as a sorbent (a substance that absorbs pollutants) at many coalburning facilities. Limestone is not found everywhere.
