Qiang Gao Qiangyong Zhang Wen Xiang Received: 22 March 2018 / Accepted: 23 May 2018 Springer International Publishing AG, part of Springer Nature 2018 Abstract Due to the exhaustion of shallow the deformation and failure of surrounding rock in resources, the underground roadway used for coal deep underground engineering. mining has reached the depth of 1000 m. The zonal disintegration phenomenon (ZDP) in deep rock mass Keywords Zonal disintegration phenomenon will appear with the increase of depth which is widely (ZDP) Strain gradient Deformation theory of different from shallow failure mode.In order to reveal plasticity Dynamic excavation Numerical analysis the formation mechanism of ZDP, a new theoretical Oscillating mode model is proposed. Based on the strain gradient theory and the deformation theory of plasticity, an elasto- List of symbols plastic damage softening model considering of u€ Two order derivative of the displacement on dynamic excavation is put forward. The dynamic time equations and boundary equations are expressed Dr The space step through the Runge–Kutta method. The numerical d Modiﬁcation parameter of the damage analysis
