Ground Pressure Distribution Features under Filling and Mining of Deep Multiple Mined-out Areas of Gaofeng Mine

Abstract

Abstract: In view of the production safety and efficiency badly threatened by the complex conditions of high stress，local broken ore rocks and multiple mined-out areas in Gaofeng Mine，the numerical model of Gaofeng mine is established with the use of ANSYS-Workbench and imported in FLAC3D to compute and to study the distribution law of ground pressure. The targeted advices of ground pressure control measures are proposed to guide the deep stoping design and mining.

Key words: Deep mining, Multiple mined-out areas, Numerical simulation, Ground pressure distribution
