Abstract

This paper presents a comprehensive technical analysis of the potential expansion of the Trebačko Brdo quarry through the introduction of deep benches, with the aim of increasing extraction capacity while maintaining slope stability and ensuring compliance with environmental regulations. The geological, geomorphological, and engineering-geological characteristics of the site indicate favourable conditions for the continued exploitation of limestone. Laboratory testing confirms the high quality of the mineral resource, particularly in terms of its chemical composition (CaO > 50%) and physico-mechanical properties (compressive strength > 100 MPa).

The proposed expansion concept предусматри the successive development of benches down to an elevation of 470 m above sea level, increasing the total extraction height to 85 m. Slope stability has been verified through a calculated safety factor (F = 3.48), while the optimal working bench width (27.5 m) allows for the integration of spiral ramps, safety zones, and drainage systems. Special emphasis is placed on geotechnical challenges, including rock mass discontinuities, interaction with groundwater, and the need for adaptive planning.

The analysis also includes an assessment of environmental impacts, with particular focus on dust emissions, hydrogeological changes, and the necessity of technical reclamation. In conclusion, the proposed pit expansion model demonstrates high technical feasibility, safety, and compliance with contemporary mining practices, thereby enabling the sustainable exploitation of technical stone at the Trebačko Brdo site.
