Underground mining operation in salt deposits requires special control over rock mass stability. Changes in stress within the rock mass cause gradual convergence of underground workings. A slow convergence process with a complex spatiotemporal distribution requires the measurements with high accuracy, which is carry out on a well-planned spatial distribution of observation network.
The aim of the study was to present the procedure of designing and implementing observations of convergence in salt caverns within a salt dome deposit in Klodawa salt mine in Poland. The studies focused on identifying the most important factors that should be considered when establishing new observation networks to assess the stability of salt rock mass. The algorithm was developed based on experiences is measurements conducted over a period of 50 years in one section of the Klodawa mine. The most significant components of spatio-temporal deformation process in 3D space were presented. Measured convergence in relation to the salt dome geometry, geological and mining condition were taken into account to design a new network in another part of salt dome. Presented experiences may originate as a premise for designing a new observation network in other salt mines where extraction is planned with the chamber and pillar method. |
