CURRENT ISSUES IN REGULATING THE STABILITY OF SLOPES IN THE DEEP ANGREN COAL OPEN PIT, CONSIDERING THE ATCHINSKY LANDSLIDE AND UNDERGROUND COAL GASIFICATION PROCESSES
The article examines current challenges in ensuring the stability of the slopes of the Angren open-pit coal mine under conditions
of deep surface mining and underground coal gasification. The study is based on the analysis of long-term geodetic monitoring
data, engineering-geological investigations, and slope stability calculations using limit equilibrium methods. The results indicate
that buttress stabilization effectively reduces the deformation activity of the Atchin landslide; however, the further development of
mining operations requires comprehensive consideration of hydrogeological, seismic, and anthropogenic factors. The findings can
be applied in the development of measures aimed at improving the stability of slopes in deep open-pit coal mines.
