针对陶庄煤矿2603工作面有巨大冲击危险性，分析了影响工作面冲击危险性的因素，采用FLAC3D数值模拟方法研究了顶板岩层破断规律及支承压力分布规律，分析了陶庄矿直接顶厚度的变化对冲击危险性的影响，并建立直接顶厚度与冲击危险性函数关系式。结果表明：煤层上覆坚硬基本顶是造成工作面冲击地压的主要因素。

In view of the giant rock-burst danger in Taozhuang coal mine 2603 working face, the factors affected the rock-burst danger in the working face was analysed. Roof strata rupture regulation and abutment pressure distribution law was studied in the way of FLAC3D numerical simulation. The influence of the change of immediate roof thickness on the rock-burst danger was analysed,and build the relationship expression between the immediate roof thickness and rock-burst danger.The results show that the hard thick roof above is one of the main factors lead to the occurrence of rock-burst.
