  • According to the water burst problem induced by exploitation of coal 8 and coal 9 in Donghuantuo mine,the hydrogelogical and engineering geological conditions are analyzed in detail.Based on comprehensively considering the effected factors of break height,the assessment model is established,and 6 types of simulated projects are designed.Using advanced software package of FLAC3D,a visual numeric simulation is conducted in analysis of break height of coal 9.
