    (2006) Preidl, Wojciech
    In this paper have shown the results of stonework lining check samples research and the chemical properties research of the water flowing in the water gallery. Basis on such analysis and investigation in situ, the author tried to valuate its technical condition. Has taken into account also results of the load on the lining calculations. The tunnel on the 2,5 km Zabrze sector was driven between 1799 and 1810. The tunnel's lining was constructed as a stonework lime mortar. For the whole period of existence the water gallery was treated by the negative environmental influence. It is predicted this conditions have negative influence on the lining's strength and stability. Comparison of the strength and stresses in the lining allowed to valuate of its stability. The research was done for using the Zabrze sector of the Główna Kluczowa Sztolnia Dziedziczna for geo-tourist route purposes.
