ABSTRACT
The Podhura quarry is situated in the Olomouc region near the town of Lipník nad Becvou. The mining company is KAMENOLOMY CR s. r. o. The first part of the paper focuses on the description of this locality. The next part describes geology and hydrogeology of this quarry. The main part of the paper addresses the problem of refraction, because in this quarry there is unstable material. The East wall of the quarry approaches to the border at the second bench (to the border of the mining permit), so it will be necessary to model the final slope of the quarry. The geological structure of the deposit is relatively unfavourable in this part, and for this reason it is necessary to calculate a new general slope of this quarry. This is described in the last part of the paper.

Keywords: Slope, stability, wall, raw material, angle
