This study investigates the relationship between radon emanation and dynamic processes in highly dispersive geological media. The research focuses on the joint monitoring of seismic effects and radon emanation in various geological environments, including clayey soils, thick boulder-pebble strata, and a powerful landslide. The results show a stable connection between radon emanation and dynamic processes caused by external impacts. The turbidity of the medium, as a statistical characteristic, can be generalized in terms of other media parameters, such as permeability. Radon emanation can reflect the degree of enrichment of the environment by underground fractures, providing information about the presence of disturbances in the geological environment in the form of cracks and a stress-strain state before and after seismic loadings. Radon observations can assess the continuity of the environment and the possibility of leaching in natural conditions. The study also explores the influence of mechanical effects on radon emanation, using seismic monitoring and cross-correlation to search for the best regression models and delayed effects of various fields. The results show that the volumetric activity of radon is influenced by factors such as atmospheric pressure, temperature, and microseismic vibrations. A regression model was developed to relate radon volumetric activity to microseismic vibrations and atmospheric pressure, showing a high coefficient of determination. The study also highlights the importance of gas permeability in the extraction of metals by leaching, as it directly affects the speed, uniformity, and efficiency of the process. Understanding the factors that affect gas permeability and developing strategies to optimize it can greatly improve metal recovery efficiency by leaching, leading to more sustainable and environmentally friendly methods in the mining and metallurgical industries. The study concludes that radon emanation can be used to monitor dynamic processes in geological media and that microvibration impacts may be applied to leaching processes, including heap leaching, without the need for special transportation of materials.This study investigates the relationship between radon emanation and dynamic processes in highly dispersive geological media.
