Alluvial exploration requires knowledge of bedrock topography, grain-size distribution, volume of overburden, de-watering issues
Routinely exploration is carried out exclusively by drilling boreholes in a regular pattern. This methodology is slow, expensive and provides only pinpricks of information.
Echo Geotech’s Solution
Continuous profiles of the subsurface using Echo Geotechnical’s non-intrusive Land-streamer ideally suited to data collection in mining environments.
MASW, SH AND P-wave data collection in a single pass
The design and data analysis of our system can efficiently cover 3-4 km/day with interpreted results provided in most case within 24-48 hrs
Seismic data integrated with targeted borehole drilling provides profiles of topography, lithology, structures, hazards, faults and veins, complex systems
Non-intrusive rapid evaluation of subsurface
Echo Geotech Advantage
The land streamer configuration provides high resolution continuous profiles over an exploration area with no surface disturbance
Land streamer profiles cost less than penetration tests and may reduce the number of penetration tests required and optimize their placement.
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
