  • Optimisation of mine water discharge by monitoring and modelling of geochemical processes and development of measures to protect aquifers and active mining areas from mine water contamination


The aim of the project was to improve the competitiveness of coal production by improving the quality of the mine water raised and monitoring the substances it contains, making the cost effectiveness of different methods of dam construction calculable, increasing the safety of mining by determining the flow paths and optimising the construction of dams between areas that are still being worked and those that have been closed down and minimising the costs incurred for draining the mines while taking the measures necessary for environmental protection into account. The different objectives have in general been reached. The box model, integrating a geochemical reaction model, has proved to be a very appropriate tool in simulating mine water rebound effects in large coal mine fields. Empirical analytical solutions can easily and for a number of applications adequately describe the development of mine water quality after flooding. Equipment and methods for monitoring mine water flows and compositions have been successfully tested and applied. Data transmission units have been developed as well. Several coal mine areas have been monitored and investigated. All results led to improved quality of modelling as well as to improved parameters for mine water management. In order to optimise mine closure and subsequent effects the results of the study have highlighted several key points linked to rebound of both the aquifer and the mine water and the type of hydraulic connections between the aquifer and the mine workings. The optimisation of dam construction has been achieved.
