Abstract
There have been proposed several stress analysis-base methods to predict microseismicity induced by deep mining. In this paper, a method named “seismic moment method” is modified to be able to take into account coal seam fracturing. Accuracy of this method is compared with conventional methods for case on the deep coal mining at Horonai coal mine. It is recognized that this method is the best to predict areas where microseismic events densely distribute, quantitative intensity of microseismicity and its variation with face advance.
