The evaluation of slope stability is a critical task in geotechnical engineering. According to the passive arch action in undercut slopes, an alternative mining method called the moving-pit is proposed. This method, in which a specific undercut area is moved at the toe of the slope, combines the concepts of passive arch action with the conventional cut-and-fill mining method. In this approach, an optimum undercut span depends on factors such as the slope geometry, the strength properties of the geo-material and the required working space for mining. The optimum undercut span should be less than the arch-based failure span of the slope while incorporating a factor of safety and providing sufficient working space for the mining operations. The proposed method offers potential benefits in stabilizing temporary slopes, particularly in open-pit mining. In this study, various physical tests were conducted to monitor the deformation of the model using a series of potentiometers and particle image velocimetry (PIV) technique. In addition, miniature pressure cells were used to monitor the distribution of earth pressure inside the model during the cut-and-fill process.
