Through these actions, BUT Géologie intervenes in the field of mines and in particular, quarries and open-pit mines, whether for the search for new operating sites, expanding existing sites or rehabilitating derelict sites.
- Terrain mapping
- Sampling works
- Search for useful substances
Section“BUT Géologie” has all the expertise and technical know-how to apply the many and varied practical applications of hydrology and hydrogeology.
BUT Géologie is specialised in the study of water catchments and piezometers. It provides you with a team specialized in the development of specifications, including water well drilling projects. BUT Géologie is also specialised in the study of water catchments and piezometers. It provides you with a team specialized in the development of specifications, including water well drilling projects.
Our office oversees the drilling process in order to optimize the dimensioning of the structure and its equipment, according to the observations of the site.
Our team performs pumping tests and interprets the removal of wells, as well as other tasks:
- Calculating the perimeters of prevention zones around all types of basins (wells, drains, sources, etc.).
- Determination of perimeters by conducting tracing tests by measuring transfer rates inside aquifers.
- Determination of aquifers characteristics (type, hydrodynamic parameters: porosity, permeability, transmissivity, storage coefficient, etc.).
- Estimation of aquifers reserves…
- Calculating the exploitation rate of a water well…
GEOTECHNICS“BUT Géologie” is your partner to perform analyses before your mining exploration projects. These include a range of operations necessary to acquire knowledge for the qualitative and quantitative evaluation of a mineral deposit. We participate in road and construction projects as well.
The different approaches taken for geotechnical projects will measure or identify the following parameters:
- Lithostratiography and subsurface geomorphology.
- Subtances levels
- The carrying capacity of a soil (penetration tests, cavity research, pressure tests, etc.)
- Selection and design of the infiltration system for wastewater or treated water (dispersal drains, infiltration bed or mound)
- Karst areas Identification
- Conception and sizing of foundation and support projects
- Geotechnical investigation checking and supervising
- Technical support on site
GEOPHYSICS PROSPECTING SOLUTIONS“BUT Géologie” offers its customers a range of geophysical prospecting solutions.
Electrical methods
Les méthodes électriques se basent principalement sur la répartition du potentiel électrique dans le sol. La mesure de résistivité électrique des terrains permet de fournir des résultats quantitatifs et qualitatifs.
L’interprétation géologique des résultats permet de distinguer les massifs de roches saines, les zones altérées, les zones saturées en eau et les accidents naturels.
Seismic methods
Les méthodes sismiques sont utiles dans le domaine du génie civil et permettent de révéler l’épaisseur des terrains facilement excitables ou de positionner le toit du substratum rocheux compact. Elles permettent aussi de mette en évidence les zones déconsolidées ou karstifiées au sein du massif calcaire ou des évaporites.
BUT Géologie assure les études d’impact des tirs de mine, sur les agglomérations ou autres sites qui se présentent au voisinage pour pouvoir établir les mesures techniques et de sécurité adéquates.
