中文摘要：
运用FLAC^3D’对煤岩组合模型冲击倾向性进行三维数值试验研究，通过改变煤岩组合模型高度比例（1：1、1：2、2：1）、夹角（0°、30°、45°）和岩性分别进行模拟，分析煤岩组合模型不同的组合模式对冲击倾向性的影响。三维数值试验结果表明：煤岩高度比例和夹角的变化，对煤岩组合模型的抗压强度影响不大，冲击能量指数和弹性能量指数随着顶板岩体厚度的增加而增加，随着夹角的增大而降低。岩性对抗压强度影响很显著，随着岩性硬度的增加，煤岩组合模型的冲击能量指数和弹性能量指数都随之增加。
英文摘要：
The FLAC^3D was applied to the study on the 3D numerical simulation experiments on the bumping tendency of the coal and rock combined model. With the change on the height scale （ 1 ： 1, 1 ： 2, 2 ： 1 ） , the included angel （0°, 30°, 45°） and the lithology of the coal and rock combined model, the different combined mode of the coal and rock combined model affected to the bumping tendency was individually simulated and analyzed. The 3D numerical experiment resulls showed that the changes on the height scale and included angle of the coal and rock would not have high influence to the compressive strength of the coal and rock combined model and the bumping energy index and the elastic energy index would be increased with the thickness of the roof strata increased and would be reduced with the included angle increased. The lithology would have remarkable i~ffluence to the compressive strength and with the hardness of the lithology increased, the bumDinz enerzv index and the elastic enerzv index of the coal and rock combined model would be increased.
