According to the well-developed joints and fragmented orebody in certain middle sections of a gold mine, combined with the stability of the ore and surrounding rock, two mining schemes were proposed, including the upward drift cut-and-fill mining method and the sublevel cut-and-fill mining method. Through a comprehensive comparison of the technical and economic indicators, as well as the advantages and disadvantages of each method, the upward drift cut-and-fill mining method was ultimately selected. The Mathews stability graph method was then employed to design the stope dimensions (height × width × length) for the primary and secondary drifts, which were determined to be 3.3 m×8.0 m × 40 m and 3.3 m×7.0 m×40 m, respectively. Based on the pre-support mechanism of anchor cables, a support scheme was designed. Discrete element software was employed to simulate the crack development state in the fractured zone, and an indicator for the surrounding rock cracking zone was proposed to quantitatively characterize the cracking depth, thereby analyzing the stability of the stope. The results show that after anchor cable support, no significant rockfall occurs in the roof of the two-step drift, and no large-scale interconnected crack zones or widespread surrounding rock cracking zones are observed. Considering both support effectiveness and economic requirements, an anchor cable pattern of 3.3 m×4.0 m is identified as the optimal solution. Under this scheme, the roof displacement is approximately 84 mm, with a reduction of 26.96%, the total number of cracks decreases by 37.33%; and the equivalent depth of the cracking zone is 0.64 m, with a reduction of 36.63%, compared to the condition without support. The field industrial application shows that the maximum vertical displacement difference of the roof after support is 91 mm. This solution brings approximately 7.555 million yuan in economic benefits to the mine.

某金矿局部中段位置节理发育、矿体破碎，结合矿岩稳固性，提出了上向进路充填采矿法和小分段充填采矿法两种开采方案。综合对比各方法的技术经济指标及优缺点，最终选择上向进路充填采矿法并以Mathews图解法设计一步骤、二步骤进路尺寸（高×宽×长）分别为3.0 m×8.0 m×40 m、3.3 m×7.0 m×40 m。基于锚索预支护机理设计支护方案，采用离散元软件模拟破碎区域裂纹发育状态，提出围岩开裂区指标定量表征开裂深度，并据此分析采场稳定性。结果表明：锚索支护后，二步骤进路顶板无明显掉块且未出现大片裂纹连接贯通区域和围岩开裂区展布；结合支护效果及经济需求，锚索网度为3.3 m×4.0 m时为最优方案，与未支护时相比，顶板位移约为84 mm，降低26.96%，裂纹总数缩减37.33%，开裂区等效深度为0.64 m，降低36.63%；现场工业应用表明，支护后顶板竖向位移差最大值为91 mm，该方案为矿山带来约755.5万元的经济效益。
