Numerical Simulation Analysis on Deformation Mechanism of Shallow-Buried Soft Rock Roadway

Abstract

The pressure control of soft-rock and roadway support has been one of the challenges of underground mines. Soft-rock support is very difficult in many places in China and is becoming a kind of main influencing factors in the development and economic of mining community. Numerical simulation research on the deformation mechanism of soft-rock tunnel contributes to the development of soft-rock support theory. The numerical calculation model of shallow buried soft-rock is based on Hongya coalmine; ANSYS is used to analysis the deformation law inward to find out how to control the soft-rock deformation. Hence we can know the main influence in the shallow soft-rock tunnel stability. The results are of great importance to the mines that have similar geological conditions.
