Accident Investigation of Mine Subsidence with Application of Particle Flow Code
The mine subsidence happened in Shandong province will be investigated and analyzed as a case study. According to the field survey study, the numerical model is established with PFC. Determining the micromechanics of rock parameters by uniaxial testing, the meso-structural features of rock and soil and the macro-mechanical response of those are linked. The model simulates the process of subside and calculates the distribution of contact force and displacement of ore particles, which have a good consistency in comparison with the actual survey data. Thus this method used into the mechanical analysis of collapse process, the displacement of ore and rock and so on, is effective.
