The application of reactive materials in the form of a Deep Permeable Reactive Barrier during and after coal conversion constitutes an innovative concept of protecting the environment from georeactor influence. The reactive materials filling the post-process cavern will make it possible to remove or immobilise the gaseous and liquid contaminants that may be subject to leaching, while also reinforcing rock mass stability. The article pays particular attention to the technical and legal possibilities for reactive ma...

The process of Underground Coal Gasification involves risks of uncontrolled/unpredictable course of the gasification process. To minimize the risks of contaminants leaking outside the georeactor zone in the event of emergency is of a significant importance when aiming to maintain safe course of the process. The article presents methods and measures aimed at reducing the risk. These methods are based on reduction of the impact of released gaseous contaminants generated during the process. In order to achieve it, a ...

The activities carried out in the georeactor area during and after the completion of the process of extracting fuels based on underground coal gasification have a significant role in minimizing the environmental impact of the technology. Selecting the optimum, most effective method of removing contaminants from the underground coal gasification process should help to increase the safety of the process. The article deals with the idea of filling a post-processing cavern. The method involving geotechnics used to fil...
