Prototypes Series

Smart Exploration Webinars Series #1: Valentina Socco and Myrto Papadopoulou

In this webinar, we propose methods which allow the effective use of surface waves in the challenging and noisy environments of mineral exploration. The methods are applicable on 2D and 3D schemes, active- and passive-source seismic data, and are highly automated and computationally efficient, suitable for large-scale applications.

Smart Exploration Webinars #2 by Dr. Bojan Brodic & Richard De Kunder

Within the Smart Exploration Project, five prototypes for innovative exploration of mineral resources have been developed by an academia-industry partnership. In this webinar, we tackle the need for innovation of the present exploration strategies and discuss in a more detailed manner two of the five prototypes: 1 – A broadband electrically driven, linear synchronous motor – LSM based seismic vibroseis source and 2 – GPS-transmitter designed to provide accurate GPS time in GPS-denied environments such as different underground spaces, mine tunnels, shafts, drifts, etc.

Smart Exploration Webinars #3 by Prof. Deyan Drganov & Katerina Polychronopoulou

In this webinar, we will present a passive seismic workflow that we proposed and applied in the context of the Gerolekas survey, in Central Greece, which was launched in the framework of the Smart Exploration project. Our workflow is based on the exploitation of the body waves of local microearthquakes and the application of Local Earthquake Tomography (LET), using the earthquakes’ P- and S-wave first arrival times, and reflected-wave Seismic Interferometry (SI), using the earthquakes’ P- and S-wave coda.

Smart Exploration Webinars #4 by Prof. Stefan Buske & Lena Braünig

Reflection seismics is an important and emerging tool for mineral exploration in hardrock environments, but often challenged by strong wavefield scattering, steeply dipping structures and non-regular source and receiver distributions. In our webinar, we show the benefits of applying focusing prestack depth imaging approaches in such cases, including its embedding in an optimum processing workflow accompanied by sophisticated velocity model building tools. A case study from a mineral deposit in Blötberget (Sweden) showcases the successful application in obtaining a high-resolution 3D seismic image cube which can serve as an excellent basis for reliable subsequent 3D geological modelling of the deposit.

Smart Exploration Webinars #5 by Per Gisselø

The developments of the new HTEM system within the Smart Exploration project, have focused on lowering the operational base frequency of the transmitter to 6.25 Hz. During this webinar session, Per Gisselø from SkyTEM will be explaining how this new system will enhance the benefits of airborne surveys not only for mineral exploration but also other industries.
