Course: Seismic methods in deep mineral exploration
30 - 3 April 2020
Purpose and intended learning outcomes
The course will provide the participants with a profound understanding of seismic methods for deep mineral exploration and consists of two parts/modules:
The classroom part/module comprises the theoretical concepts, practical implementations and case studies, including basic, as well as state-of-the-art approaches in seismic data processing and imaging for surface and borehole based seismic methods, and in particular designed for the application in deep mineral exploration surveys.
The theoretical knowledge gained during the 1-week classroom lecture will be complemented by a 1-week fieldwork part/module with a focus on seismic survey design and hands-on training with modern seismic data acquisition hardware and field equipment (borehole and surface seismics).
Prerequisites (academic, special skills needed)
General knowledge about principles of geophysics and in particular seismic methods.
Schedule and time plan
1 week classroom (30.03. – 03.04.2020)
1 week field work (autumn 2020 at COSC-2 drill site, Sweden)
Venue for classroom work and field/lab work
Classroom: PC lab of TU Freiberg.
Fieldwork: COSC-2 drill site, Sweden.
Content and modules
Module 1 (”classroom teaching”):
- Introduction: the role of seismic methods in deep mineral exploration
- Basic principles and physics of seismic wave propagation
- Elasticity theory
- Body and surface waves
- Reflection and transmission of seismic waves
- Seismic scattering and anisotrop
- Seismic data acquisition
- Survey design: principles, practicalities, limitations, common setups (2D/3D, surface/borehole)
- Hardware (sources: explosives, Vibroseis; receivers: characteristics, specifications, operation
- Seismic data processing
- Data formats
- Data quality enhancement and noise suppression (filtering, etc.)
- Velocity analysis
- Computer exercise
- Add-on: Seismic modeling (tools for forward modeling of seismic wavefields, including computer exercise
- Seismic imaging
- Pre- and poststack / time and depth imaging approaches
- Advantages and disadvantages, limitations
- Computer exercise
- Seismic interpretation
- Interpretability of seismic sections and images
- Comparison and joint interpretation with other geophysical methods
- Interpretation exercise
Module 2 (”fieldwork”):
- Introduction to the installation of seismic field equipment (sources and receivers) and data acquisition hard- and software
- Setup of field survey components along seismic profile lines and within a borehole
- Field operation and scheduling during the survey and preliminary analysis (quality control) of acquired data
Instruction and course literature
Classroom lectures and computer exercises using existing software.
The field component will include instruction in small groups.
For the classroom part/module, an exam is taken at the end of the classroom week.
For the fieldwork part/module, a report has to be compiled which includes detailed descriptions of the chosen setup and survey design, the data acquisition parameters and examples of the acquired data sets with a preliminary analysis.

Application criteria and priority
- A diverse mix of participants is desired.
- Priority will be given to students affiliated with EIT Raw Material organizations, but applications are welcomed from other academic institutions and industry.
- Course size is limited to 16 participants.
Accommodation (room and board)
Approximate accommodation costs in Freiberg: 50 Euros per day.
Accommodation costs in the field are expected to be about 70 Euros per day.
Travel to Freiberg is best via Berlin.
Travel to the field will start in Uppsala, Sweden.
S+H, insurance, Safety equipment and clothing
Insurance required for fieldwork. Safety equipment will be provided.
Successful admissions will be considered for a stipend to offset costs of accommodation and food, and when possible travel. As a requirement, the stipends are awarded to participants that are registered for all courses within one theme. Applicants that intend only to participate in a single course (or two courses) within one theme will not be considered for stipends. There is no registration fee to participate in courses offered through I-EDDA-RS.
