Impact of Mining Disturbance on Highway Sustainability: A Case Study of Aleksinac Mine Area, Serbia

Underground coal mining in expansive basins has led to land subsidence, posing significant threats to the aboveground structures and the environment. Addressing this issue is paramount, necessitating accurate and reliable prediction methods. This study introduces a novel approach to forecast subsidence and deformations along Highway E75, Belgrade–Niš, situated in the influence zone of the Morava Pit at the Aleksinac mine. The prognostic calculation was conducted using the MITSOUKO software package rooted in the stochastic Patric-Stojanović method, and based on the obtained results, a spatial analysis within the geographic information system (GIS) was performed. Additionally, the sustainability of the highway segment affected by mining activities was evaluated. The data from geodetic measurements indicate that the developed model demonstrates exceptional proficiency in simulating mine subsidence and deformation processes. Precise forecasts of subsidence and deformation, along with accurate risk assessments, are essential prerequisites for developing and implementing effective measures to mitigate the impacts of mine-induced subsidence on highways. This investigation could play a vital role in the feasibility assessment of reopening the Aleksinac mine, potentially presenting lucrative and environmentally sound solutions amidst current energy challenges.
