Affected by Dahanling overturned anticline

complex structure developed in the hinterdeep of the fourteen coal seam

and the steeply inclined seam near axis and two wings of the anticline is the high stress section

with the preference of bursting.Firstly

mine model including complex coal seam structure is established using ANSYS finite element software

and the excavation of the right wing and the axis is simulated utilizing element birth and death technology

Secondly

the stress and displacement of the surrounding rock is analyzed.Thirdly

the dangerous section of rockburst is identified

and finally the occurrence mechanism of rockburst is studied.Result shows that the hinterdeep of the fourteen coal seam has the preference of bursting

so the work against rockburst must be carried out before mining.This research provides a theoretical technical support for avoiding rockburst accident

and is of important value for reference.
