Numerical simulation of surrounding rock activity and mining pressure regularity in Haoda mine fully mechanized working face

This article according to the overburden rock structural features and the geological conditions of HaoDa coal mine, based on the scene investigation and study and the ore presses the monitor, after the numerical simulation of mining face and roadway, surrounding rock stress and deformation were analyzed during mining, According to the data of the ore presses the monitor, mastering the mine pressure appear law, which can for safely, efficiently and reasonably in the coal mining provides the basis.
