Application of dedicated software for balancing water systems of a deep mine

Abstract

Abstract Balancing the systems of waters in mines or in selected parts of them is an important part of works carried out by geological services of the mines, including the works aiming, for instance, at recording the types of waters flowing into mine excavations, assessing the impact of mining operations on the environment and foreseeing water threats. The article presents research performed with the objective of balancing the selected water systems of the deep coal mine “Jankowice.” The research was performed with the help of the software dedicated directly for balancing water systems, in particular water systems in mines. The computational methods of this software are based on the techniques of matrix calculations, in particular on the methods of results coordination. It allows to obtain fully compliant balances with minimal adjustments of the measured values describing both the types of the system incoming waters and collective waters which are a mixture of types of waters incoming to the system. The results of the conducted research showed the usefulness of the KYBL software for balancing the water systems of deep mines. It was also shown that this tool could also be used to balance any other water systems with a similar physical mixing model as in the case of deep mine water systems.
