The Three-Dimensional Similar Simulation of Stress Regular Pattern of Roof of Large Mining Height

Abstract:

Based on the distribution of in-situ stress and the special conditions of the large mining height in one mining area, the author conducted the analogy stimulation test of the mine pressure behavior and the roadway deformation law. This research, mainly based on the geographical conditions of 1 to 2 coal seam of this mining area, stimulated the mine pressure behavior of the working face and the roadways, as the mining height is 5meters and 6meters. Through this analogy stimulation test, the mine pressure behavior of working face, in the mining process with large mining height, is analyzed and summarized.
