Abstract (English): This article presents a comprehensive study on the management and optimization of frame-anchor support systems for seam preparatory excavations designed for the transportation of large-tonnage cargo via suspended monorail transport. With the intensification of underground mining operations and the increasing use of heavy mechanized transport, ensuring the stability and safety of mine workings under dynamic load conditions has become a critical challenge for engineering. The research proposes an innovative support technology based on the combined fastening of monorail systems to the crowns of metal arches and directly to the roof using deep-embedded anchors. This approach aims to reduce dynamic impacts on the excavation roof and improve the overall reliability of the support system. To evaluate the effectiveness of the proposed support design, a numerical modelling method was employed to simulate the interaction of components within the dynamic system "suspended monorail - support - rock mass." The stress-strain behaviour of the frame-anchor structure under real load scenarios was analyzed using SolidWorks Simulation software. During the simulation, various parameters were systematically varied, including the spacing of support frames, the length and anchorage depth of the rock bolts, and the mechanical properties of the surrounding rock mass. The results of the analysis enabled the identification of rational design parameters that minimize deformation and enhance load-bearing capacity. In particular, optimal combinations of frame spacing and anchor configurations were found to significantly reduce stress concentrations and improve the stability of preparatory workings under dynamic loading from moving monorail trains. The study demonstrates that effective management of support system parameters can lead to improved safety, reduced material consumption, and faster development of mining panels. The findings have practical significance for the design of underground transport routes and can be incorporated into normative documents governing support systems in dynamically loaded mine environments.

Abstract (Croatian): Članak prikazuje sveobuhvatno istraživanje o upravljanju i optimizaciji okvirno-sidrenoga sustava podgrade u pripremnim jamskim iskopima namijenjenima transportu tereta velike nosivosti pomoću visećega jednotračnog željezničkog sustava. S intenziviranjem podzemne eksploatacije i sve većom primjenom teških transportnih sustava osiguranje stabilnosti i sigurnosti jamskih prostorija pod utjecajem dinamičkih opterećenja postaje jedan od ključnih inženjerskih izazova. U radu je predložena inovativna tehnologija podgrade koja se temelji na kombiniranome učvršćenju jednotračnih željezničkih sustava - spajanjem na tjemena metalnih okvira te izravnim sidrenjem u krovnu stijensku masu pomoću dubokih sidara. Cilj takva pristupa jest smanjenje dinamičkih naprezanja u krovini iskopa i povećanje ukupne pouzdanosti sustava podgrade. Radi procjene učinkovitosti predložene konstrukcije podgrade primijenjena je numerička metoda modeliranja kojom je simulirano međudjelovanje komponenti u dinamičkome sustavu „viseća jednotračna željeznica - podgrada - stijenska masa". Analiza ponašanja stijenske mase pri naprezanju i deformacijama provedena je primjenom softverskoga paketa SolidWorks Simulation. Tijekom simulacija sustavno su mijenjani različiti parametri, uključujući razmake između okvira podgrade, duljinu i dubinu usidrenja sidara te mehanička svojstva stijenske mase. Rezultati analize omogućili su određivanje racionalnih konstrukcijskih parametara koji minimiziraju deformacije i povećavaju nosivost podgrade. Posebno je utvrđeno da optimalna kombinacija razmaka okvira i konfiguracije sidara znatno smanjuje koncentracije naprezanja i poboljšava stabilnost pripremnih prostorija pod djelovanjem dinamičkih opterećenja nastalih kretanjem jednotračnih željezničkih kompozicija. Provedeno istraživanje pokazuje kako učinkovito upravljanje parametrima sustava podgrade može dovesti do povećanja sigurnosti, smanjenja potrošnje materijala i ubrzanja napredovanja jamskih radova. Dobiveni rezultati praktično su primjenjivi u projektiranju podzemnih transportnih ruta te se mogu ugraditi u normativne dokumente koji reguliraju projektiranje i primjenu podgradnih sustava u dinamički opterećenim rudarskim okruženjima.
