研究了一种新的冲击地压控制方法，即煤体振动方法的机理。在实验上，采用分形几何方法，研究了煤体在受振后裂隙的变化规律，发现受振后煤体的分形维数增大，表明煤体的裂隙增加，且经过一定振动时间后，分形维数趋于稳定；研究了振动对煤体力学性质的影响，发现受振后煤体的抗压强度、弹性模量和降模量降低，且受振时间越长或初应力水平越高，振动对煤体力学性质的影响越明显。应用采煤工作面和巷道冲击地压的分析结果，从理论上证明了煤体受振后煤岩体的稳定性增加 A new method of rockburst control is studied, which is the mechanism of coal body vibration method. In the experiment, fractal geometry method was used to study the variation law of coal after fracture. It was found that the fractal dimension of coal increased after vibration, indicating that the fracture of coal increased, and after a certain vibration time, the fractal dimension The effect of vibration on the mechanical properties of coal was studied. It was found that the compressive strength, elastic modulus and modulus of decrease of the coal after vibration, and the longer the vibration duration or initial stress level, The more obvious the influence of mechanical properties. Applying the analysis results of coal mining face and roadway rock burst, it is theoretically proved that the stability of coal and rock mass increases after the coal is subjected to vibration
