The article presents information and results of assessing the stability of the near-pit wall rock mass of the Central Pit at the Akzhal deposit, as well as the technogenic risks arising from the interaction between open-pit and underground mining operations. Based on a developed step-by-step modeling algorithm consisting of six stages, a comprehensive analysis of the geomechanical conditions determining the probability of collapse of the southern pit wall was carried out. At the 1st stage, geomechanical risks in the active mining zones were assessed; the 2nd stage focused on identifying and locating potentially hazardous areas affecting transport communications and infrastructure. At the 3rd stage, the natural stress field of the rock mass was determined, allowing clarification of deformation zones; the 4th stage included the analysis of engineering-geological, geodetic, and geomechanical investigation results. The 5th and 6th stages involve slope stability calculations and the assessment of how identified deformations influence the safety of underground mine workings. The study results showed that the southern wall of the Central Pit is in a state of limiting equilibrium and exhibits a high probability of sudden collapse. It was established that underground mining using a caving system contributed to the formation of zones with increased rock mass displacement, which is confirmed by modeling data. Additionally, specific geomechanical conditions were identified between the open-pit space and underground workings, creating an elevated collapse risk. The findings emphasize the need for comprehensive geomechanical monitoring and the improvement of technogenic risk management methods under combined mining conditions.
