Relevance. The stability of pit walls is a key factor determining the safety and efficiency of open-pit mining operations. Excessive groundwater inflow and the presence of water-saturated zones often lead to slope instability, landslides, and reduced productivity. Therefore, developing effective methods for dewatering pit wall massifs is of great practical significance for ensuring sustainable mining operations. Objective. The objective of this study was to develop and implement a comprehensive system for draining the pit wall massif using newly designed horizontal and slightly inclined boreholes with camouflet cavities to enhance slope stability. Methods. The research methodology involved advanced groundwater interception in formation zones beyond pit boundaries and interception of surface runoff along pit slopes using horizontal, slightly inclined boreholes with camouflet cavities. Experimental investigations were carried out using a polarization optical setup to analyze stress distribution within the rock mass. Field studies included drilling horizontal boreholes in areas of maximum groundwater accumulation, creating camouflet cavities by controlled blasting, and assessing stress redistribution in the dewatered rock mass. The results demonstrated that camouflet cavities formed beyond the rock mass displacement line act as stress concentrators that effectively unload the near-contour zone and enhance slope stability. The introduction of horizontal, slightly inclined boreholes with camouflet cavities ensures efficient drainage of the contour massif, reduces stress concentrations at the slope base, and stabilizes the overall pit wall structure. The proposed set of measures can be widely applied at mining enterprises under similar geological and hydrogeological conditions, contributing to improved safety and productivity in open-pit mining. © 2025, National Academy of Sciences of the Republic of Kazakhstan.
