EFEE (European Federation of Explosives Engineers) Newsletter February 2019 discusses space based infrastructure deformation monitoring system SILLE developed by Datel. Active mining processes can cause seismic activity, negatively affecting communities and infrastructure. Satellite monitoring can identify subsidence and structural defects that are otherwise undetectable. Read Datel´s article on pg 37-45.
• Systematic monitoring of large or small areas
• Coverage of the entire world
• It works in all weather conditions
• Giving early warning by monitoring and evaluating safety risks that emerge slowly and cannot be seen with visual inspection
• Indicating places where additional inspections should be carried out
• High accuracy measurement comparable to geodetics
• Survey wide areas without a tripod
• Subscription based service - pay per use
• Applicable to all stages of construction - planning, construction, operation
• After a failure or structural problem, data can show the reasons it occurred and prove that prevention was impossible
• Parallel historic and modern displacement for a broad understanding of local ground subsidence
• Minimize cost of community distrust and physical damage Sille offers a proactive tool for structural integrity monitoring and
disaster prevention. In addition to identifying if surrounding construction, mining, or geological subsidence has caused deformation
or structural weaknesses, the service also allows users to develop a timeline for existing subsidence related issues, including data that
land or structural deformities preexisted construction or mining work.
Sille’s data can bolster transparency in the mining industry by assessing land and surrounding structures before and after mining to detect
possible movement. This data can also be used as evidence to show that mining has in fact not caused any damages.
