The Importance of Geology and Engineering Geolology Studies in Reducing Uncertainties and Risks in Aggregate Production Sites

ABSTRACT:Materials produced in rock quarries have many uses, such as concrete and cement raw material, asphalt and embankment aggregates and railway ballast. Aggregate production activities, which are mostly carried out in urban areas, are a risky activity due to geological, environmental, social, legal and economic uncertainties. Projects based on technical and scientific data have reduced uncertainty and risks; furthermore, projects developed with transparent and consistent data, will ensure that all internal and external stakeholders have accurate information about project risks.

The quality expectations of rocks change according to their planned use. Many quarries exhibit parametric differences within very short distances. For example rock composition and texture, organic material and shell content, structural characteristics, weathering types and their products, and the presence of dangerous substances can all vary. For this reason, pre-operation geology and engineering geology studies should be carried out in the quarries.Determining the composition and quality changes of the rocks in the quarries and the geological, hydrogeological, geotechnical and environmental risks will play an important role in the quarry and facility planning. The aim of this study is to emphasize the importance of detailed geology and engineering geology surveys in reducing uncertainty and risks in quarry areas.
