After a long preparation phase that began in August, the data acquisition phase of the seismic survey took place between the 15th and 29th November.
Here are some key figures:
30 kilometres of seismic line, divided into 3 lines
25 people deployed = 3,600 working hours
0 work-related accidents
14 days of acquisition work
76 hours of pure acquisition activity
3 vibrator trucks (+ 2 as back-up)
1,317 points vibrated (out of 1,332 planned)
5,498 sensors deployed
13 sensors destroyed or missing
1 TB of raw data recorded
The “Service géologique de l’État” and Smart Seismik Solutions would like to thank all the local authorities and infrastructure network managers for their excellent cooperation, as well as local residents and drivers for their understanding and patience. The results of the seismic survey are expected in March.
On Saturday the 11th of November, The National Roads Administration (Administration des ponts et chaussées) and the company Smart Seismic Solutions are hosting an open day. This event will present the equipment that will be used in the seismic exploration campaign in the Minette basin, which is due to start shortly. Here you can experience live how the subsurface is explored with vibrations generated by special trucks and recorded by seismic sensors (“geophones”).
Where and when?
11 November 2023, from 1pm to 4pm, near the sports fields behind the car parks north of the Neischmelz site. View map.
Further information on the project and the route of the measurements can be found at www.seismik.lu.
In the week of the 16th October, three exploratory boreholes with seismic measurements are drilled to test the properties of the near-surface geological layers (loose sediments).
To perform these seismic measurements, a weight is dropped on the surface to create vibrations, which are recorded using geophones installed at varying depths in the boreholes.
These boreholes were located near the “Kayler Poteau”, close to the N3, and at the foot of Mont St. Jean in Dudelange-Budersberg. Due to their shallow depth and the large distance kept to all buildings, any influence on those can be excluded.
