compensatory measures properly implemented that will serve to prevent, reduce, and eliminate
or compensate the expected changes.
20.4.1.1 Air
From the analysis conducted, it is established that the activities of the Pulacayo Mining Project
will have the following main environmental impacts:
Alteration of air quality by the generation of particulate matter.
Change in air quality by generating combustion gases.
These environmental impacts have negative characteristics with an assessment of moderate to
critical, therefore specific measures need to be done, whether preventive, corrective or
compensatory according to each case for mitigation.
In the case of particulate matter generated by drilling and blasting, the effects can be minimized
by implementing a ventilation system inside the mine, which must be consistent with the
engineering of the project, can be from simple chimneys to systems of injection and extraction of
air. In any case, it should be verified that the final output does not exceed the permissible limits of
quality and aspects such as population and downwind direction should be considered. There is
also the application of wet drilling techniques and the implementation of dust traps at the mouth
of the drills.
20.4.1.2 Soil
Among the most significant environmental impacts that would affect the ground, we have:
Changes to soil quality by inappropriate disposal of domestic solid waste.
Changes to soil quality from spills of fuels and lubricants.
Alteration of soil levels structure.
Soil compaction.
Alteration of soil quality due to the accumulation of waste material in dumps.
Alteration of soil quality for tailings disposal.
Changes to soil quality from spills of hazardous substances.
Changes to soil quality by improper final disposal of special solid waste (accessories and
spare parts for vehicles and machinery, discarded tires, non-hazardous solid sanitary
waste, debris).
Possible soil erosion due to loss of vegetation layer.
Alteration of soil quality due to sedimentation of heavy metals from DAM (Mine Acid
Drainage) and DAR (Rock Acid Drainage).
Negative impacts previously mentioned, only three reach the Critical category.
Among the preventive measures, it is intended to do:
