摘要
通过对石膏矿采空区顶板大面积冒落情况的调查,利用数值模拟方法对共有的规律进行研究,得出了重要的结论,并提出了监测和预防采空区项板大面积冒落的措施。
Some significant conclusions are obtained by the investigation of roof fall over great extent of mine worked-out area in mine, and a numerical analysis of the rule caused by roof fall and measures against roof fall are put forward.
