Stability Evaluation and Monitoring System of A Shaft in Jinchuan No.2 Mine Area
摘要
Abstract
After analysis of the shaft damage reasons, the different reinforcement measures and the corresponding construction plan have been taken for the engineering characteristics of different rock segments. The influence of mining underground to the shaft repaired has been studied by establishing a numerical model in the identical condition of reinforcement measures, the corresponding geological conditions and mining order. The Numerical simulation experimental results showed that the shaft is a certain degree damage risk with the deeper mining. According to the engineering distribution between the shaft and ore bodies, the distributed optical fiber sensing technology has established a dynamic monitoring system for long-term monitoring and predicting rock mass deformation accurately.关键词
