Dynamic Stability Analysis and Forecast of Surface Mine Dump ()
Abstract
Malugou Dump is close to Jinduicheng Molybdenum surfaces mine and affected by blasting vibration all its lifetime, it is meaningful to monitor the blasting vibration and analyze the stability of dump under blasting vibration so as to ensure the safety of the dump. Firstly, dynamic test was done about Malugou Dump. Then dynamic stability analysis of the dump is simulated with Geo-studio software. The results show that the present blasting vibration has little effect on the dump and the safety factor of dump under blasting vibration is about 1.158, which indicates that Malugou Dump is safe. At last, the relationship between safety factor and maximum single explosion charge, the horizontal distance between monitoring points and blast source and elevation difference is obtained by simulating and regressing, which can be used as a guidance of production blasting in Jinduicheng Molybdenum mine.
