Abstract According to the analyzation of the process and influence factors of advanced deep hole blasting，its prevention and control mechanism for rock burst was demonstrated. The prevention effect was studied by changing the angle of blasting hole and the length of charge weight with ADINA numerical simulation software and its field practice effect was approved by different detecting methods from stress field and energy field. When the depth of the blast hole certain，the peak stress of high stress areas before workface reduce or transfer to deep coal at the three blasting hole arrangement in sector，which make the whole structure of coal-rock in a relatively stable low state. Furthermore，the angle of blasting hole larger and the length of charge longer，the shear stress decreasing zone bigger and the effect of rock burst control more obvious.

Key words： mining engineering advanced deep hole roof blasting rock burst ADINA simulation software three blasting hole arrangement in sector
