| Summary: | The mining activities have a large environmental influence on areas direct and indirectly affected by this activity.
The Permanent Protection Areas (APPs) noteworthy in terms of degradation from mine extraction. Among the acid rocks
that compose the geology of Paraí-RS, the lower acid section shows horizontal structure failed where the rock slabs are
extracted to produce stone-cut. Initially, the mining activity areas were bounded by Google Earth on Paraí-RS. After that,
a new bound was proposed for the lower acid section. The APPs were bounded according to the National Forest Code
of 2012. Finally, the zoning of the lower acid section was defined with feasible exploration, excluding the APPs overlapping
the areas. The basalt mining activity represents about 1% of the territory of the Paraí-RS. Slightly more than half of this
activity was in areas with Title Mining of National Department of Mineral Production (DNPM). Paraí-RS area is covered
by 22% of APPs. Slightly more than 15 hectares of these areas were degraded by mining activities. The feasible areas for
mining activities exploration represent about 13% of the Paraí-RS territory. |
