Abstract EN
In the development of underground spaces, we found that the mechanical properties of rock mass often demonstrate strong nonlinear characteristics.
Some new phenomena emerge in deep rock mass engineering.
This includes zonal disintegration and rock burst.
Zonal disintegration is very important in deep tunnels.
In this paper, we start with the mechanical properties of deep rocks to understand the preconditions for zonal disintegration.
Using the Failure Approach Index (FAI), the process of zonal disintegration can be modeled by FLAC (FISH language).
Our results indicate that tensile failure in the Supporting Pressure Zone (SPZ) is a precondition for zonal disintegration.
Various factors that affect the generation of zonal disintegration are studied.
When the maximum stress is in the axial direction, zonal disintegration will be present in deep tunnels.
The high axial stress is necessary for zonal disintegration.
We will present a zonal disintegration simulation in one coal mine for comparison with the borehole teleview data.
We suggest some measures to prevent the development of zonal disintegration.
