    Workshop D: Acoustic Emission monitoring of Rock fracturing and deformation tests

    Tuesday, Oct. 10th, 2023

    Fracture imaging

    The workshop combines an overview of the physics behind fracture initiation and propagation in brittle materials, with practical examples of the use of microseismic and acoustic monitoring for the imaging of the fracture process. The examples include laboratory rock deformation tests, hydraulic reservoir stimulation in the field and fracturing associated to caving in mining. Passive and active methods will be examined, with examples at reservoir and laboratory test scales. The workshop will cover the following points:

    • Principles of fracture initiation and propagation
    • Fractures and seismicity
    • Passive imaging of fractures
    • Monitoring fracture interaction and coalescence
    • Seismic source parameters
    • Source mechanism: fault plane solution and moment tensor
    • Active surveys: deformation and fracturing imaging

    Participants will be provided with tutorials covering the topics presented in the workshop and a 1-week licence of our seismic processing software to practice and navigate through the examples of monitoring of fracturing processes at field and laboratory scales.

    Workshop G: Deep Mining Geomechanics

    Tuesday, Oct. 10th, 2023

    Aim of the workshop: To sustain the contribution of the mineral industry to the world’s economy, mining activities should take place beyond a 2,000 m depth. Violent and uncontrolled failure of rocks in deep mines is a severe threat to this goal. This workshop aims to present recent research in the area of deep mining and to facilitate discussions to exchange knowledge from research to practice. It will discuss Rock behavior and its failure in deep underground openings.

    Semmering base tunnel

    Construction of the Semmering base tunnel was started in 2012. The tunnel has a length of 27,3 kilometers and consists of two running tunnels. Excavation works are nearly finished and the concrete works for the inner lining where started in 2020. The base tunnel is part of the new 470 kilometer long railway line between Vienna and Villach which should be completed by the end of 2030.

    The tour begins with the presentation of the complete project and continues with a visit to the building lot SBT2.1 - tunnel Fröschnitzgraben.  You will see the impressive installations for the underground works which are supplied over two 400 meter deep shafts. After entering the tunnel system by one of the shafts you will be shown the running works on the two single line tunnels. The participants will be supplied with the necessary clothing and split up into groups for the visit.

    Brenner Base Tunnel

    The Brenner base Tunnel (BBT) is a low gradient tunnel with a length of 55 km running between Innsbruck (Austria) and Fortezza (Italy) and therefore a cross border tunnel of European importance. The tunnel has two single bores by a diameter of 8.1 meters and a distance between the two running tunnels between 40 and 70 meters. Every 333 meters the two tunnels are connected by a cross passage. As a speciality this base tunnel has an exploratory tunnel over the full length.

    The site visit will beginn in the modern information center called „Tunnelwelten“ in Steinach am Brenner with a project presentation. After a short lunch break you tour will take you underground to see the emergency station St. Jodock and an assembly cavern for one of the TBM’s as well as the crossover tunnel. At the end you will be shown the large landfill
    area Padastertal.

    Field Trip D

    Tauernmoos

    With the construction of the pump storage power plant Tauernmoos the ÖBB (Austrian federal Railway company) are adding a very important asset to their existing power plant at Tauernmoos for the production of electricity for the rail infrastructure.

    The two existing reservoirs Tauernmoossee and Weißsee with a difference in altitude of 220 m will be connected by an underground pressure shaft. The power plant will finally have a pump turbine capacity of 170 megawatts and an annual production of 460 GWh.

    The excursion will start with a visit to the existing power plants Uttendorf 1 & 2. After a half hour drive to the site office at Enzingerboden you will be offered a small snack and fitted with the needed tunnel gear to explore the underground works at an altitude of up to 2300 m. The highlight will be a visit to the large machine chamber, the pressure shaft and the inlet trumpet.

    Finally you will get the chance to enter the control tunnel underneath the existing concrete arch gravity dam Tauernmoos.

    Field Trip E

    Limberg III

    VERBUND Hydro Power GmbH (VHP) started construction on the Limberg III power plant in 2021. The project is a pumped storage power plant with a total capacity of 480 megawatts. Like Limberg II, which was put into operation in 2011, it will be constructed entirely underground between the two existing reservoirs of the Mooserboden (final level 2,036 m) and Wasserfallboden (final level 1,672 m).

    These two reservoirs with a total capacity of 160 million m³ will be used as upper and lower basins for the pump turbine operation to generate electricity. This is an addition to the existing power plants Limgerg I and Limberg II which are already in operation

    The new headracetunnel starts at the intake of the Mooserboden reservoir and reaches the pressure shaft after 3.7 km. After a length of 600 m the pressure shaft leads via two distribution pipes into the underground power station, which is located underneath the Limberg dam. The power station consists of a machine chamber with two 240 MW hydroelectric sets and a transformation chamber, connected via two generator dissipation tunnels. After the turbines the water is returned  to the Wasserfallboden reservoir via a 613 m long tailrace tunnel.

    In the powerhouse cavern, two hydroelectric sets generate electricity, each consisting of a reversible Francis pump turbine and a generator. The energy is dissipated with a nominal voltage of 380 kV from the cavern system by means of a gas insulated line and is connected to the existing energy dissipators. 

    After a short project presentation you will visit the building site at an altitude of over 2000m.  The existing reservoirs at Moorboden and Wasserfallboden as well as the landfill site of Drossen will be on your tour before going underground to see all the different excavation sites. At the time of your visit you will mainly see the ongoing concrete works. At the end of your visit you will be invited to a meal in the site canteen before leaving for Salzburg.

    The fees include:

    The participation fee includes participation in the conference and the trade exhibition, the conference bag, the buffet lunch and a concert on Wednesday, 11.10.23.

    Only persons under 26 years of age, without a regular income, are considered "students" (reduced participation fee). Doctoral students have their own price category. For both, proof of study must be uploaded at registration.

    You will receive your name badge (participant card) as well as all other conference documents exclusively at the conference desk in the congress center (NO participant documents will be sent out!).

    The fee for on-site participation also includes virtual access. The contributions will be stored and will be available (arround 3 weeks after the congress) for viewing online via our website until the end of the year 2023. 

     

    ATTENTION:

    • The festive evening in the Stieglkeller is NOT included in the price - this must be booked separately!
    • Workshops can only be booked in conjunction with the congress!
    • Virtual participation: We do not guarantee the reception of the live streaming

    Accompanying Persons

    There is no separate program for accompanying persons. All options such as sightseeing programs or the festive evening can be booked individually. All accompanying persons are cordially invited to the Welcome Reception and the concert.
