为获得天体引潮力和煤与瓦斯突出的相互关系,从天体引潮力对地质灾害的影响角度出发,以Mohr-Coulomb准则和牛顿第二定律为理论基础,采用理论分析、数值模拟和统计分析的方法对其进行研究。结果表明:煤与瓦斯突出与天体引潮力之间存在一定的相关性,引潮力对突出的发生具有一定的推动作用,两者都表现出时间上周期性和空间上地区差异性,且在引潮力作用最强时,突出发生的频率高,作用最弱时,突出发生的频率低。数值模拟结果也验证了天体引潮力对突出的发生具有一定的推动作用。研究结果为进一步认识煤与瓦斯突出机制提供了新的研究方向。
In order to obtain the relationship between the tide force of celestial body and the relationship between coal and gas outburst and the influence of celestial tide force on geological disasters, based on the Mohr-Coulomb criterion and Newton’s second law, the theoretical analysis, numerical simulation and statistical analysis Method to study it. The results show that there is a certain correlation between coal and gas outburst and celestial tide force, and the tide force has a certain promotion effect on the outburst of the celestial bodies. Both of them show the periodic and spatially regional differences in time, The strongest role in the force, highlighting the occurrence of high frequency, the role of the weakest, highlighting the occurrence of low frequency. The numerical simulation results also verify that the tide force of celestial body has a certain impetus to the salient occurrence. The results provide a new research direction for further understanding of coal and gas outburst mechanism.
