Abstract

In order to have a better understanding on the stability of roadway surrounding rock in QingFeng coal mine. Protodyakonov's theory is used to evaluate its stability theoretically, then a numerical simulation is conducted to analyze the stability of roadway surrounding rock in natural state by using the phase2 finite element software. The stress distribution law and strain distributing disciplinarian are gained, the total displacement and the strength factor of the surrounding rock are also obtained by numerical simulation. The results show the deformation of roadway surrounding rock is small and the two joints around roadway have great influence on the stability of roadway surrounding rock. The comprehensive application of the two methods can provide an important reference for stability evaluation of other roadway surrounding rocks
