Abstract:In the process of deep mining extension of Maoping mine, the ground pressure problems such as deep high-stress and rock burst are increasingly prominent. In this work, the numerical simulation and analysis on the typical geological profile of the mine were conducted by PHASE software. It is found that the natural isolated pillar between different ore bodies is the most obvious area of stress concentration, and the rock strata movement upward to 45° direction of the upper plate is the maximum displacement deformation. The ground pressure movement law can provide a reference for the construction of the ground pressure monitoring system. Based on the PHASE simulation analysis results and the mining technical conditions, the ground pressure monitoring scheme design and the monitoring system were carried out. The microseismic time and space evolution rule and deformation failure characteristics of surrounding rock in the process of dynamic mining are got through the ground pressure monitoring and analysis, which can provide technical basis for the follow-up ground pressure disaster prevention and control.
