【摘要】 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。更多还原

【Abstract】 Theoretical analysis,numerical simulation and statistical analysis are applied to study the relationship between coal-gas outburst and astro-tidal-triggering based on the Mohr-Coulomb criterion and Newton’s second law from the astro-tidal-triggering influence on geological disasters. Results show that there is a certain correlation between coal-gas outburst and astro-tidal-triggering and the tidal force plays a certain role in promoting the coal-gas outburst. Coal-gas outburst and astro-tidal-triggering both exhibit a periodicity in time and regional difference in space. Coal-gas outburst occurs at high frequencies under the strongest tidal force,while it occurs at low frequencies under the role of the weakest tidal force. Numerical simulation results verified the correctness of the tidal force?s role in promoting the coal-gas outburst. A new research direction is provided to further understand the mechanism of coal and gas outburst.更多还原
