The Impact of Quarrying: Cause and Effect
Air Pollution from quarrying. Dust from quarry sites is a major source of air pollution, although the severity will depend on factors like the local microclimate conditions, the concentration of dust particles in the ambient air, the size of the dust particles and their chemistry, for example limestone quarries produce highly alkaline (and reactive) dusts, whereas coal …

Health Hazards of Mining and Quarrying
In longwall mining, dust generation can be reduced by cutting coal in one pass (rather than two) across the face and tramming back without cutting or by a clean-up cut. Dust dispersion on longwall sections can be reduced with homotropal mining (i.e., the chain-conveyor at the face, the cutter head and the air all travelling in the same direction).

Unfortunately, limestone mining can put biodiversity at risk. A limestone quarry can destroy or disrupt underground caves that are home to numerous species of life. In some cases, a species may only be able to survive in a particular cave, so a single limestone mine can wipe out an entire species. 6. Dust-Related Health Hazards
