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 karst. Although this doesn't hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.

Answer: Limestone deposits are found throughout the world. They are "mined" in a process known as "quarrying." This process varies depending on the use of the product. If it is to be made into cement, it is needed in small pieces so that it can be ground and calcined. In this case, the rock has h...

Mining. Limestone has been a valuable resource since Missouri became a state. In early open pit operations, limestone was mined and crushed by hand and removed from the quarries by mules, carts and tramways. Limestone is now mined using surface and underground methods. Surface quarrying is the most common method of producing limestone in Missouri.
