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.
Some Issues in Limestone Mining. Limestone is most often mined from a quarry. However, underground limestone . mines are found at places in the central and eastern United States, especially in and near cities. Underground mining of lime - stone has some advantages over surface quarrying and will probably increase in the future.
