摘要
利用ANSYS,对多因素影响下的底板突水破坏进行数值模拟分析:随着开采的进行,煤层底板采空区中部出现拉应力区;开采区域两侧的底板岩体内,距离岩壁10 m^15 m的范围是应力峰值区;底板岩层内部应力分布随着开采的进行而不断变化。底板塑性区随着开采而向深部发展。
In the light ANSYS,this paper makes the numerical simulation the floor inrush water under the effect of many factors. As the mining goes on, there appears drawing stress area in the middle of coal floor. Peak value stress of area is in the scope of 10～15 meter to rock wall on the two sides. The distribution of stress in floor continually changes and the plastic section in floor develops deeper during mining.
