Environmental Hazards of Limestone Mining | Education ...

Limestone mines use two types of blasting. Small explosive charges set along drilled lines free blocks of stone to be removed for construction. Large charges reduce whole areas of limestone to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and dust.

How Does Limestone Affect the Environment?

Apr 09, 2020 · 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.
