Abstract

According to the appeared incident dynamic pressure of 1304 working face in a mine, the characteristics of electromagnetic emission signal were analyzed before the dynamic pressure occurred; FLAC3D was used to simulate the impact on pressure relief effect under the conditions of different borehole diameter, space and depths. The results showed that: electromagnetic emission intensity and pulse signals continual increase could be a symbol of shock hazard; the larger the borehole diameter, the smaller the borehole space, the greater the depth of the borehole, and the better relief; borehole depth must exceed a certain range of stress concentration area, otherwise pressure relief effect was not obvious, and even increased the possibility of shock hazard. Based on the above findings, rock burst local prevention and control integration technology of “electromagnetic emission forecasting technology drilling to determine the range of the risk large-diameter borehole pressure relief technology effects checking through electromagnetic emission” which was applied successfully was established
