To address the challenges of slope stability and ground pressure control during the transition from open-pit to underground mining in Jinchuan Longshou Mine, the stress evolution and plastic zone variation laws of the open-pit slope and orebody surrounding rock during underground stoping and backfill process were analyzed with numerical simulation. The results show that:Underground mining leads to the formation of an elliptical subsidence area on the surface of the open pit, where the subsidence displacement is positively correlated with the mining depth, and the maximum subsidence displacement reaches 1.53 m; underground stoping induces a significant redistribution of the secondary stress field, with the compressive stress in the bottom area of the open pit decreasing from 2.0 MPa to 0.1 MPa, forming a low-stress relaxation zone penetrating to the surface; the plastic zones are mainly distributed at the bottom of the open pit and the toe of the south slope, while the backfill body effectively restricts the plastic zone from extending deep into the slope, and there is no penetrating plastic zone inside the slope body, indicating the overall stability of the slope. In the subsequent deep mining process, it is recommended that microseismic monitoring and multi-point displacement observation should be strengthened in areas with developed plastic zones. Meanwhile, the backfill roof-contact rate should be strictly controlled to prevent local surrounding rock caving from inducing slope instability.

针对金川龙首矿露天转地下开采过程中边坡稳定性与地压控制难题，采用数值模拟分析了地下回采-充填过程中露天边坡及矿体围岩应力演化与塑性区演变规律。结果表明：地下开采会导致露天坑地表形成椭圆形的沉降区域，沉降位移与开采深度正相关，最大沉降位移为1.53 m；地下回采诱发了明显的次生应力场重分布，露天坑底区域压应力由2.0 MPa降至0.1 MPa，形成贯穿至地表的低应力松弛区；塑性区主要分布在露天坑底部及南坡坡底，充填体有效限制了塑性区向边坡深部扩展，边坡坡体内无贯穿塑性区，表明边坡整体稳定。在后续深部开采过程中，建议加强塑性区发育区域的微震监测与多点位移观测，同时严格控制充填接顶率，防止局部围岩冒落诱发边坡失稳。
