Question 1
The construction of an open-pit coal mine like the one suggested in this document has
possible negative effects on various environmental factors. Each such effect on these
factors calls for appropriate mitigation actions for acceptable standards to be attained.
The survey provides a more thorough evaluation of the likely impacts and mitigation
measures for 12 environmental aspects.
Air Quality
Impact: The particulate matter and emissions produced by the operation of the mine,
its equipment and blasting operations may affect the local communities, as it poses a
health hazard, mainly respiratory diseases.
Mitigation: Palliative measures such as use of water sprays in the dust-prone areas
and fitting machinery with filters to control particulate release should be adopted.
Water Resources
Impact: The process of mining, for instance, may lead to pollution of the water bodies
available for the local communities’ use due to the deposition of contaminants through
runoff, affecting the aquatic life.
Mitigation: Protective dikes around water sources should be constructed, and the
treated wastewater should be used to cleanse the impurities before the effluent is
released into the environment.
Soil Quality
Impact: The chemical substances utilized in mining activities along with soil erosion
can help in decreasing soil productivity and consequently there is going to be an
impact on the farming activities carried out in the surrounding regions.
Mitigation: Use management of any potential causes of pollution that may lead to the
wearing of the soil that is through planting ground cover and use of measures that
promote non-toxic materials.
