摘　　要：为了研究地表尾矿干堆对井下开采的影响,建立了余华寺矿区三维模型,利用FLAC3D分析软件,对地表尾矿干堆进行了模拟,最终得出地表干堆对井下生产水平的应力和位移几乎没有影响,而对近地表部分影响大。上盘矿岩接触带和矿体走向两端出现了高应力区,需要对此处重视并采取有效措施,以保证矿山正常生产。In order to find the influence of surface dry-tailing stacking to underground mining, a three-dimensional model for Yuhuasi Mining Area was established, and FLAC3D analysis software was used to simulate surface dry-tailing stac- king. The results show that surface dry-tailing stacking has almost no effect on the stress and displacement of production lev- el but a great impact on near-surface part. More attention on and effective measures for high stress area in hanging wall con- tact zone of rock and ore and two ends of ore-body trend need to be taken in this mining area to ensure normal production of the mine.
