Study of Sand Mining and Related Environmental …

2017-6-19 · The study showed that two types of sand mining, namely instream and flood plain mining, are practiced along the Nzhelele river valley. Instream mining involves the extraction of coarse sand suitable for concrete slabs whilst flood plain mining involves the extraction of fine sand suitable for brick laying and plastering. Results of the field investigation revealed that instream mining is the prevalent type of sand mining in the study area and accounts for about 51% of the sand mining operations along Nzhelele River whilst flood plain mining only constitute 44%. A very small percentage (5%) of the operations employ both instream and floodplain mining in the study area. It was found that floodplain mining was rarely practiced around the mouth of the river and because more deposition of river sand occurs along these communities. Communities closer to the source of the river host both instream and floodplain mining. Field studies confirmed that floodplain sand extraction activities are causing severe impacts on agricultural lands and the vegetation on the floodplains. Data collected from the field revealed that sand mining …
