基于UDEC软件的凉水井煤矿工作面强制放顶研究

Study on face forced caving in Liangshuijing Mine based on UDEC software

运用UDEC软件模拟凉水井煤矿工作面强制放顶距离及效果,对工作面上覆岩层运动情况进行分析,得出合理的放顶距离,掌握基本顶来压规律,避免由于工作面初次来压和周期来压产生的不良后果。

By simulating face forced caving of Liangshuijing Mine using UDEC software,the paper analyzed the overlying strata movement law,determined the reasonable caving distance,mastered the roof pressure law and avoided the effect of roof pressure.
