Two critical factors, namely intense precipitation and intricate excavation, can trigger rock mass disasters in mining operations. In this study, an indoor rainfall system was developed to precisely regulate the flow intensity of precipitation. A large-scale model experiment conducted on a self-designed physical simulation platform investigate failure instability high-steep slopes under unsaturated conditions. The real-time reproduction progressive process enabled determination revealed mechanism underlying slope instability. Experiment results indicated that may be primary factor contributing instability, while continuous pillar exacerbates extent failure. stage occurs at 40 mm/h, whereas exceeding 50 mm induce reaching up 60 will result improved region growing segmentation method (IRGSM) subsequently employed for image recognition deformation underground mines. Herein error comparison with simple linear iterative cluster (SLIC) superpixel original (ORGSM) showed average identification X Y directions by reduced significantly (1.82% 1.80% IRGSM; 4.70% 6.26% SLIC; 9.45% 12.40% ORGSM). Ultimately, relationship between probability analyzed using Monte Carlo method. Moreover, stability assessment criteria condition were quantitatively accurately evaluated.
