摘要：Engineering disasters occur frequently and violently with the increase in mining depth,which is mostly due to insufficient study on the failure mechanism of the deep rock mass.In this paper,theoretical and experimental researches on the failure behaviors and deformation control of deep surrounding rock in recent years were reviewed.Macro/meso failure mechanism of deep rock or coal-rock combined body under different loading conditions have been systematically investigated.Stress gradient failure theory of surrounding rock,uniform strength support in the deep roadway,and the analogous hyperbola movement model of overlying strata were preliminary established and a combined grouting control technology for surface and underground was proposed.Abovementioned achievements are expected to offer theoretical bases and technical supports for the exploitation of China's deep mineral resources in the future.
