| Abstract: |
| The stability of slopes is a crucial factor affecting the safety of open-pit mines. Rationally determining the safety factor of slope stability is key to ensuring the safety of open-pit mining. This paper selected four typical profiles of high and steep slopes in a granite mine in the Guangdong-Hong Kong-Macao Greater Bay Area as an example. The stability of the slopes was studied using the Bishop method, the Morgenstern-Price method, and the strength reduction method, effectively evaluating their stability. The research results indicate that the overall slope safety factors of the four typical design boundary profiles under three different conditions all meet the required values of the regulations. Additionally, the limit displacement value of the mine is calculated, the stress concentration zone of the mine is identified, and engineering measures are proposed for the actual situation of the mine. This is important for guiding the safety production of the mine. |
