Abstract

Abstract: In order to understand the stress and strain of the complex overlying strata with horizontal offset in service time of mining, the model of the overburden mining regions is created by PFM with the simulation platform of PFC3D. The overlying strata contains five layers including intrusive igneous rock, of which the bottom rock has anticline and syncline structure due to tectonic stress. The stress and strain characteristics of the five layers of rock mass are analyzed. Studies show that it takes the compressive stress 379 years to penetrate the overlying strata. The strongest penetrate path of the compressive stress is also determined. The simulation demonstrates the optimal path of roadway through the layer and identifies the correspondence between the service time of mining and the construction position of mining roadway.
