Abstract :
Based on the unascertained theory, the paper elaborated exhaustively the modeling processes of the unascertained measure model. Combined with the unascertained measure model, the safety factors affecting coal seam-roof stability are analyzed and evaluated. According to the reality of Bofang coal seam-roof stability, we can collect the measured data, determine the safety evaluation index, calculate for example by using the model, and evaluate the safety level of coal seam-roof stability lying in six points of the third coal in Bofang coal-mine. The result is found to be in accordance with the reality, after it is verified .The method is designed to enhance the effectiveness of coal seam-roof stability safety evaluation, as provided the proper safety measures basis for the departments concerned.
