摘要
采用FLAC3D的模拟方法,对单一采场的裂断拱发展演化规律和复合采场的裂断拱发展演化规律进行了模拟分析,得出了近距离煤层群上行采场结构空间在单一采场与复合采场两种不同的情况下采场上部裂断拱的演化规律及变化形态。
Simulation analysis were done on breaking arch developing and evolving process of both single stope and compound mining field by FLAC3D, evolution law and change shape of breaking arch at stope upper part of short distance coal seams uplink stope structure space under single stope and com- pound mining field two different situations were obtained.
