Paper Title:
On Stability and Support Measures of Rock Mass Surrounding the Diphead of a Coal Mine
  Abstract

The instability of the roadway is a general problem for most of the deep mine roadways due to high geo-stress and large deformation, which require that the more reasonable and effective support measures are designed and employed. By applying the 3-D explicit finite difference software FLAC3D, this paper establishes the numerical calculation model of a roadway located in about 700m depth based on the geologic condition of the site which the roadway is in as well as the results of the in-situ stress measurement and the laboratory tests for the physical-mechanical properties of rock. Furthermore, three different support scenarios are raised and the optimum one is determined by calculating and analyzing the distribution of the plastic zone and displacement field in the rock surrounding the roadway with the above three scenarios.
