In order to address the shortcomings of sampling check or fixed-point indicators of the conventional regional prediction methods and achieve a continuous monitoring of coal seam outburst risk,a new method for a dynamic pre-diction of microseismic monitoring area in the seams with coal and gas outburst potential is proposed. Accordingly the indicator evaluation system is established,and some application tests have been carried out in coal mines. The results show that the microseismic monitoring frequency indicators and energy indicators satisfactorily monitor coal seam min-ing disturbance and geological abnormal body,and the regional stress field distribution obtained by seismic wave CT detection is consistent with theoretical distribution. This verifies the feasibility of microseismic monitoring technology in the regional monitoring of outburst-prone coal seam. The study breaks the limitations of conventional methods in time and space dimension,and realizes a dynamic and continuous monitoring of coal and gas outburst-prone region.
