Quarries for cement industry
Year2000 to ongoing
LocationEurope
DescriptionTypical questions encountered in quarry investigations concern overburden and weathering thickness, excavability assessment, rock characterization, detection of faults and cavities. With geophysical techniques, large areas may be covered with a dense network of profiles, showing a much more continuous image of the subsurface than scattered boreholes. The position of the boreholes can be optimized, resulting in better information at lower cost.

 

A few examples of projects related to quarries :

 

Year:  2010                                              
Location:Slovakia
Description:  
Rock mass characterization prior to quarry extension has been carried out. This investigation includes detection of faults and karstic zones, assessment of overburden and weathered thickness, delimitation of sound rocks zones and boreholes location optimization.
Technique:Electrical Resistivity Tomography

 

Year:2008
Location:France
Description:  
Geophysical methods have been used to locate weathered and fractured limestones over the extension quarry site. The results show that weathered and fractured limestones correspond to dry valleys and these zones have been map for exploitation planning of the quarry.
Techniques:Electrical Resistivity Tomography and Seismic Refraction Tomography

 

Year:2006
Location:Belgium
Description:  
Borehole geophysics has been used to detect geometry of planes structures (stratification, fractures,…) and local features (cavities, karst structures,…) within the bench of a quarry. Fissure system, which can trigger off landslide, has been detected and solutions have been taken to ensure the safety of the area.
Technique:Borehole radar in reflection mode
