Measurement campaign for long range laser scan at Most lake (Czech Republic) / RFCS RAFF project

In September 2019, Ineris performed a LiDar 3D survey of the shores of the artificial Most lake (Czech Republic). Seventy-five metres deep, this lake was created by flooding an old open-pit lignite mine.

This measurement campaign falls within the framework of the European RAFF (Risk assessment of final pits during flooding) project, initiated in 2019 for a period of 3 years. Its objective is to evaluate the risk of instability in flooded mine reservoirs, and to establish a methodology to ensure their long-term monitoring.
The data thus acquired will be combined with a sonar survey in order to accurately reconstitute the complete geometry of the reservoir and its banks. It will then be used for the benefit of Ineris and its partners, in order to develop 3D digital models. The models allow us to understand the influence of geomaterials and geological properties on the stability of reservoir slopes, both in the short and long term.
By contributing to this project, Ineris thus shares all of its expertise and know-how based on significant amounts of feedback from its experience of long-term management of residual risks in the post-mining and extractive industry, for the benefit of other partner organisations.
