Mine side slope stability control method
The invention provides a mine side slope stability control method, and belongs to the field of geotechnical engineering. The mine side slope stability control method mainly comprises the following steps of (1) sampling on site and measuring physical parameters; (2) establishing a mathematical model, and judging the stability of an initial state; (3) carrying out instability feedback, realizing initial stability by modifying a weak plane inclination angle; (4) secondarily judging the stability of a side slope subjected to the dynamic load through a finite element numerical calculation iteration method; (5) dividing the range of a plastic zone; and (6) reasonably arranging grouting, anchoring and large-diameter drilling control methods on a slope body. According to the mine side slope stability control method, on the basis of on-site actual conditions, a theoretical foundation is laid for mine slope stability analysis by adopting a mathematical physical analysis method of solid mechanical stress analysis and Newton linear iteration, and the purpose of controlling the slope stability is jointly achieved by pertinently combining grouting and anchoring to control a separation layer of the plastic zone and relieving pressure of a large-diameter drill hole.
