摘　　要：随着开采深度越来越大,蚕庄金矿上庄矿区深部地压显现现象日趋严重,开采过程中顶板及两帮岩石垮落失稳现象频繁发生,甚至出现岩爆现象,严重制约矿山生产。为了保证安全生产,利用数值模拟技术,以深部7336及7337两个大跨度相邻采场为例,对开采过程中的稳定性进行模拟分析。通过研究发现,在单层开采过程中,两个采场的顶板中部区域为应力及塑性区集中区域,要注意支护;在多分层开采中,下盘断层带附近应力集中现象明显,为重点关注区域。With the increasing depth of mining,the phenomenon of deep ground pressure in Shangzhuang mining area of Canzhuang Gold Mine is becoming more and more serious.Rock collapse and instability occur frequently in the roof and two sides during the mining process,and even rock burst occurs.These problems seriously restricts mine production.In order to ensure safety in production,numerical simulation was used to simulate and analyze the stability of mining process in deep longspan 7336 and 7337 stopes.It was found that in the process of single-layer mining,the central area of the roof in above two stopes was the concentrated area with stress and plasticity,so attention should be paid to support.In multi-layer mining,the phenomenon of stress concentration near the footwall fault zone was obvious,which was the focus area.
