Combined with the situation of the de-stressing boreholes implementation of Henan energy Yi coal company Geng cun coal mine 13210 face, using the large-scale numerical simulation software FLAC, simulated and analyzed the reasonable hole diameter of the de-stressing boreholes in13210 working face, it is concluded the reasonable hole diameter, which provides the basis for rockburst of working face using borehole pressure relief.
