At Vibrometric, we specialize in innovative borehole and tunnel seismic methods, essential for precise resource characterization. These techniques are designed to minimize uncertainty in mineplanning and development, without impacting ongoing production and operations.
With over 30 years of experience, Vibrometric stands as Finland’s leading authority in seismic investigations for the comprehensive characterization of hard rock sites. Our expertise and dedicated research and development efforts have positioned us at the forefront of seismic site characterization.
Our services include identifying mineralized zones and their lateral and in-depth delineation, mapping lithological contacts and structural features such as faults, dykes, and folds. We also specialize in determining rock properties, including elastic moduli, porosity changes, and fluid content, as well as assessing fracture and stress orientation to understand rock anisotropy.
3D Vertical Seismic Profiling (VSP) is an advanced geophysical technique used to obtain high-resolution images of the subsurface by recording seismic waves from different azimuths and depths. This method involves deploying receivers within boreholes and using surface or near-surface seismic sources to create a three-dimensional view of the geological structures. 3D VSP is particularly valuable for characterizing hardrock sites, mine sites, storage facilities, and waste disposal sites, providing detailed insights into their structural and stratigraphic features.
3D seismic imaging from tunnels leverages the unique access provided by tunnel walls and boreholes to generate comprehensive images of the structures surrounding and ahead of tunnel pathways. By utilizing seismic waves reflected and transmitted through the geological formations, this technique allows for the precise mapping of potential hazards and geological features, significantly enhancing safety during both the construction and operation phases of tunnel projects.
2D reflection seismics involves emitting seismic energy into the ground and recording the reflected waves to create a two-dimensional cross-sectional image of the subsurface. Examples of its use include mapping coal deposits to understand their extended geometry, as well as delineating the associated structural setting, such as fault lines and folds, which can impact mining operations. 2D reflection seismics is also widely applied in groundwater investigations and environmental studies, providing essential information for resource management and project planning.
3D seismic surveys are a geophysical technique used to create a three-dimensional model of the Earth’s subsurface. These surveys are used for a variety of purposes, including assessing potential mining sites, planning for underground storage facilities, and understanding geological hazards. The depth, scale, and resolution of the data obtained from 3D seismic surveys make them invaluable for accurately mapping and characterizing the subsurface, enabling more informed decision-making and reducing the risks associated with subsurface exploration and development.
In the context of subsurface exploration, Side Scan Seismic Profiling from boreholes can reveal detailed information about the orientation, continuity, and properties of geological formations, fractures, and other features adjacent to the borehole. It’s commonly applied in areas where ultra-high-resolution imaging of the lateral variation in geology is crucial, such as in the planning of tunnel routes, the assessment of potential hazards in mining operations, and the detailed characterization of mineral resources. The method enhances the ability to visualize and interpret complex subsurface conditions, aiding in more accurate modeling and decision-making processes.
Cross-hole Seismic Surveys are used for several key applications, including evaluating the mechanical properties of the ground for engineering projects, assessing the integrity and quality of concrete in foundations or dams, and characterizing subsurface geology for resource exploration and environmental studies. Cross-hole seismic data is crucial for constructing accurate models of the subsurface, aiding in the design and implementation of construction projects, the assessment of potential hazards, and the optimization of resource extraction techniques.
