Aiming at the mechanical characteristics of backfill in high-level stopes of Zhongguan Iron Mine in Hebei Province, analytical models for lateral pressure, shear stress and vertical stress of high-level stopes were established, and the influence laws of stope width, height and length on the stress distribution of backfill were clarified. A strength design model for backfill in high-level stopes with stress distribution taken into consideration was proposed, and the reliability of the model was verified through engineering application. The results show that the lateral pressure reaches the maximum at the bottom of the backfill on the side contacting uncemented or low-ratio cemented backfill; the shear stress increases first and then decreases, peaking at the middle of the backfill, and is significantly affected by stope width and height; the vertical stress of backfill increases linearly with stope length; when the stope length exceeds 45 m, the influence of exposed height on vertical stress becomes gradually prominent. Based on the comprehensive consideration of the stress distribution characteristics of backfill, the shear force at the contact surface of the surrounding rock and the included angle of the horizontal plane, three types of backfill strength design models were constructed. In combination with the working conditions of Zhongguan Iron Mine, a differentiated strength design scheme was selected. Industrial tests on site have verified the accuracy and reliability of the proposed backfill strength design model.

针对河北中关铁矿高阶段采场充填体的受力特征，通过构建高阶段采场侧压力、剪切应力与垂直应力解析模型，探明采场宽度、高度及长度对充填体应力分布的影响规律，提出考虑应力分布的高阶段采场充填体强度设计模型，并通过工程应用验证模型的可靠性。结果表明：在与非胶结或低配比胶结充填体接触侧充填体底部侧压力达到最大；剪切应力呈先增大后减小的变化趋势，在充填体中部剪切应力达到最大，且受采场宽度和高度影响显著；充填体垂直应力随采场长度呈线性增长，采场长度超过45 m后暴露高度对垂直应力的影响逐渐显著；综合考虑充填体应力分布特征、围岩接触面剪切力与水平面夹角，构建了3种充填体强度设计模型，结合中关铁矿的工况条件，提出了差异化强度设计建议。现场工业试验验证了充填体强度设计模型的准确性与可靠性。
