3. The Environmental Impacts of Aggregate Extraction ...

While a bag of stones or gravel may look fairly benign, the process of getting it to us is anything but benign. Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate ...

Gravel Extraction - an overview ScienceDirect Topics

The most obvious and immediate impacts of sand and gravel extraction are physical ones arising from the following. • Substrate removal and alteration of bottom topography. Trailer suction dredgers leave a furrow in the sediment of up to 2 m wide by about 30 cm deep but stationary (or anchor) suction dredgers may leave deep pits of up to 5 m deep or more. Infill of the pits or furrows created ...

The impact of gravel extraction on the sea-bed and on the herring and sand-eel fisheries is discussed. It is estimated that the resources of marine gravel in the southern North Sea will be depleted within 50 years whereas the fisheries will be practised for many hundreds of years to come. Therefore a careful evaluation, on a European level, is needed of the relative short-term benefits for the ...

SECTION 11: GRAVEL EXTRACTION - everysite

Gravel is usually extracted from rivers and burns in an attempt to increase the flow of the river by deepening or widening the channel, to deepen shallow zones for fish movement, or simply to provide gravel for road or other building work. Movement of gravel within a river system is a vital natural process. Gravel extraction will therefore inevitably have knock-on effects and can be extremely ...

Sand Extraction: 1. Introduction - GreenFacts

Despite our increasing dependence on the colossal quantities of sand and gravel being used and the significant negative impact that their extraction has on the environment, this issue has been mostly ignored by policy makers and remains largely unknown by the general public. Indeed, the absence of global data on aggregates mining makes environmental assessment very difficult and has ...
