Shallow Exploration
(20-300m depths)
Geotechnical engineering relies on a thorough understanding of the subsurface to ensure safe and stable structures. Design Parameters are the critical factors we evaluate to inform your project’s foundation design. These parameters include:
Shear moduli: This measures the soil’s stiffness, a crucial factor in determining its ability to resist loads and deformations.
Bedrock profiling: Knowing the depth, type, and characteristics of the underlying bedrock is essential for foundation design and excavation planning.
Soils lithology/continuity: Understanding the soil types (lithology) and their continuity (distribution and layering) allows us to assess the soil’s strength, bearing capacity, and potential for settlement.
By evaluating these design parameters, we can provide a comprehensive picture of the subsurface conditions and ensure your project is built on a solid foundation.
Deposit Delineation and Valuation
Echo Geotechnical empowers you to make informed decisions about your mining project with our comprehensive approach to deposit delineation and valuation. We utilize advanced exploration techniques to provide you with a clear picture of your resource:
Volume Calculations: We map the 3D geometry of your deposit, allowing for accurate estimations of total resource volume.
Bedrock Topography: Understanding the underlying bedrock topography is crucial for mine planning and efficient resource extraction. Our services provide this vital information.
Applications
Echo Geotechnical’s expertise in shallow exploration plays a vital role throughout the mining project lifecycle. We offer valuable services for two key stages:
Mineral Exploration: Our innovative techniques assist in efficiently locating and characterizing potential mineral deposits. This allows you to focus your exploration efforts on the most promising areas.
Mine Planning: Once a viable deposit is identified, accurate data is essential for effective mine planning. We provide the detailed subsurface information you need to optimize mine design, pit layouts, and resource extraction strategies.
Mineral Exploration
THE PROBLEM
Accurately exploring alluvial deposits presents unique challenges. Geologists need a comprehensive understanding of several factors, including the shape of the underlying bedrock, the size distribution of the valuable minerals, the amount of overburden (waste material) present, and potential dewatering issues.
Traditionally, exploration has relied heavily on drilling boreholes in a grid pattern. However, this method is slow, expensive, and only provides limited data points, like pinpricks of information in a vast area. This limited data can make it difficult to get a clear picture of the entire deposit.
ECHO GEOTECH’S SOLUTION
Echo Geotechnical offers a faster, more cost-effective solution for alluvial exploration. Our non-intrusive Land-streamer technology provides continuous profiles of the subsurface, ideal for data collection in mining environments. This innovative system can collect valuable MASW, SH wave, and P-wave data in a single pass, significantly reducing fieldwork time. Our efficient design allows us to cover 3-4 kilometers per day, and you’ll typically receive interpreted results within 24-48 hours.
Beyond speed, the Land-streamer offers a wealth of information. By integrating seismic data with targeted borehole drilling, we can create detailed profiles of the topography, soil composition (lithology), geological structures, potential hazards like faults and veins, and even complex underground systems. This comprehensive picture empowers you to make informed decisions about your alluvial exploration project. In short, Echo Geotechnical provides a rapid, non-intrusive method for evaluating the subsurface, giving you the actionable data you need to move forward with confidence.
OUR ADVANTAGE
There are two key advantages to using Echo Geotechnical’s Land-streamer technology for alluvial exploration. Firstly, it provides high-resolution, continuous profiles across your entire exploration area. This detailed information is captured without disturbing the surface, minimizing environmental impact.
Secondly, the Land-streamer method is typically less expensive than traditional penetration testing methods. In many cases, the detailed data it provides can even reduce the number of boreholes needed, or help you strategically place them for the most impactful results. This translates to significant cost savings for your alluvial exploration project.
Mine Planning
THE PROBLEM
Mining planning requirements include assessing the minerals deposits’ extent and quality:
- Irregular or complex deposits are often not well defined by drilling alone
- Mineral Sands – volume calculations dependent on accurate mapping of layer thickness/shape which can be highly variable
Optimizing shaft placement and design requires not only a clear understanding of the mineral deposits shape and extent but also the location of geo-hazards such as faults and voids.
ECHO GEOTECH’S SOLUTION
Seismic data integrated with targeted borehole drilling provides early profiles of topography, lithology, structures, hazards, faults and veins, complex systems.
OUR ADVANTAGE
The land streamer configuration provides high resolution continuous profiles over a mine plan area with no surface disturbance. Land streamer profiles cost less than borehole drilling and may reduce the number of boreholes required and optimize their placement. Extended seismic profiles potentially revealing new unexplored areas.
