【 摘 要 】

This paper presents the method of performing forecast of the influence of exploitation planned in seam 503 by the "Bobrek" Unit of "Bobrek-Piekary" Coal Mine on the Holy Cross Church in Bytom - Miechowice. It contains the analysis of church construction and history of its renovations, geological and mining conditions in the church area as well as deformations it underwent as a result of mining exploitation conducted so far. Forecast of influences of planned exploitation was performed with the use of EDBJ program, a formula for subsidences by J. Bialek, applying the best local values of parameters of this formula in the sense of the least-squares method. The analyzes presented herein were used to assess the possibility of conducting planned exploitation in the context of protecting this church.
