Study of Numerical Simulation on Damage and Reliability of Rock Mass Slope of Open Mine
The rock mass slope stability of open mine has the varied characteristic with mining and accumulating damage progressively, and only the safe and stability within the ages of service is kept. The paper aims at geological characteristic of the south slope of Yanqianshan open iron mine, using joint network simulation technological to analyze and determine the rock mass damage tensor and probability distribution parameter initially. Basing on FLAC- 3D software as the basic simulation platform, the varied law of the joint rock mass slope reliability and damage with dropping of mine is studied and discussed according to applying damage mechanics and Rosenblueth principle . By establishing the varied reliability evaluation models of the rock slope under the stope descending condition gradually, the slope safety and reliability in the different mine depth is more truly determined. The Study has shown that the failure risk of the south slope of Yanqianshan open iron mine can be accepted.
