The open stoping method is mostly used in small and medium-sized iron mines with medium stability of ore and rock. In practical application, it is easy to induce large-scale caving of roof and surrounding rocks in goaf, which seriously threatens the safety production of mines. The complex and irregular goaf group left over by the open stoping method in Zhuba Iron Mine in Nanjiang city was taken as the research object. Through surface point cloud data obtained by high-precision UAV aerial photography, combined with the mine production plan maps, a refined three-dimensional numerical model of the ore and rock was constructed, and the dynamic evolution laws of the mechanical characteristics of the surrounding rock of the goaf groups were studied. The following conclusions are obtained. The height, volume, area, and quantity of the goaf at the 1 318 m middle section are all the maximum values, which are the key factors restricting the safe mining of the lower ore body. The residual ore body at the 1 318 m middle section and the residual horizontal pillar directly facing the goafs at the 1 258 m middle section are not suitable for mining. To ensure the safe mining of the lower ore body, a systematic protection scheme for the caving hazards and impact airwave hazard of the goaf group was proposed. The engineering practice results show that approximately 188 900 tons of ore were recovered from the 1 258 m middle section, and no large-scale caving occurred in the goafs of the 1 318 m middle section during the mining period; during the mining of the central orebody of the 1 208 m middle section, caving of varying degrees occurred in the goafs of the 1 318 m and 1 258 m middle sections, but the caving hazards did not affect the production area, verifying the safety and practicality of the proposed caving hazard protection scheme.

空场法多用于矿岩中等稳固的中小型矿山，在实际应用中易诱发采空区顶板及围岩的大规模冒落，严重威胁矿山安全生产。以南江县竹坝铁矿空场法遗留的复杂不规则采空区群为研究对象，通过无人机高精度航拍获取地表点云数据，结合矿山生产平面图，构建精细的矿岩三维数值模型；对采空区群围岩力学特性动态演化规律进行了研究。结果表明：1 318 m中段的采空区高度、体积、面积和数量均为最大，是制约下部矿体安全开采的关键因素；1 318 m中段残留矿体和1 258 m中段直接面临采空区的残留水平矿柱均不宜开采。为保障下部矿体安全开采，提出了采空区群陷落危害和冲击气浪危害的系统防护方案。工程实践结果表明，1 258 m中段回采矿量约18.89万t，开采期间1 318 m中段采空区未发生大规模冒落；1 208 m中段中部矿体开采期间，1 318 m和1 258 m中段采空区发生不同程度的冒落现象，但冒落危害并未对生产区域造成影响，验证了该冒落危害防护方案的安全性和实用性。
