Short summary
This paper presents the implementation of probabilistic analyses to assess environmental risks while improving the productivity of the in situ coal conversion process. Parametric modelling was employed for the Máza–Váralja (Hungary) coal deposit, and parameter uncertainty was undertaken to identify the potential risks to human health and the environment. The outputs of the parametric study focused on assessing reactor stability, fault integrity, surface subsidence, and hydraulic processes.
