摘　　要：针对太阳、地球、月亮这些星球的活动对发生冲击地压的影响问题,采用理论分析及实例验证的方法,主要研究了由于地球自转速度的变化而引起地球上不同纬度间的应力差对发生冲击地压的影响,在一年中容易发生冲击地压的月份,太阳活动对发生矿震的影响,以及月球-太阳潮应力对发生冲击地压的影响。结果表明星球活动能明显地改变地壳的应力状态,进而影响冲击地压的发生,所以是控制冲击地压发生的一个重要因素。太阳、地球及月亮这些星球的活动对矿井处于临界失稳状态的煤岩体发生冲击地压有显著的作用。Influence of celestial body＇s activity on rock burst occurrence is researched by theory analysis and explained with the statistical data of rock burst accidents in Chinese coal mines. The stress-difference among the different latitudes induced by the variety of earth rotation velocity affects the rock burst occurrence. Furthermore, the lnonths when rock burst easily occurs in one year, the influence of solar activity on mine quake occurrence, and the influence of moon-sun tide stress on rock burst occurrence are also analyzed. Celestial body＇s activity can obviously change the crustal stress state, further affect the rock burst occurrence, so it is one of the important factors controlling the rock burst occurrence. The activity of the sun, earth and the moon has obvious influence on rock burst in the coal and rock body in the state of critical instability.
