Aiming at the problems of large ore depletion rate and serious surface subsidence in Shizhuyuan Polymetallic Mine by caving mining, it is proposed to use filling mining method. Physical and chemical properties test of tailings, static and dynamic flocculation and settlement test were carried out, combined with the actual production capacity of the mine, the optimum thickening parameters of tailings and thickener size were determined. The particle swarm optimization support vector machine (PSO-SVM) was used to establish the sand discharge stability prediction model, and the optimum sand discharge process parameters were obtained. The results show that the optimum type of flocculant is CKYZ-24S, its optimum dosage is 30 g/t, the optimum feed mass concentration of the unclassified tailings is 12.5%, the optimum feeding rate of the tailings is 0.744 t/(m2h), and the diameter of the thickener is determined to be 12 m. The optimum sand discharge process parameters are as follows: the height of the tailings mud layer is 15.2 m, the thickening time is 3.9 h, the flow rate of sand discharge is 96 m3/h, and the average mass concentration of slurry is 70%, with fluctuation of ± 1.5%, which realizes 24 h continuous filling of tailings, and the filling capacity reaches 4 800 m3/d. The research results show that the filling mining method can improve the economic benefits and ensure the green and safe mining of the mine.

针对柿竹园多金属矿采用崩落法开采存在矿石贫化率大、地表塌陷严重等问题,提出改用充填采矿法开采。开展了尾砂物化性质试验、静动态絮凝沉降试验,结合矿山实际生产能力,确定了尾砂最佳浓密参数和浓密机尺寸,并应用粒子群优化支持向量机(PSO-SVM)建立了放砂稳定性预测模型,得到了最佳放砂工艺参数。结果表明:絮凝剂最佳种类为CKYZ-24S,其最优掺量为30 g/t,全尾砂入料最佳质量浓度为12.5%,尾砂最佳给料速度为0.744 t/(m2·h),确定浓密机直径D=12 m。最佳放砂工艺参数为:尾砂泥层高度15.2 m、浓密时间3.9 h、放砂流量96 m3/h、料浆平均放砂质量浓度70%,质量浓度波动控制在±1.5%,标准偏差为0.71,实现了尾砂24 h连续充填,充填能力达4 800 m3/d。研究结果表明,采用充填采矿法开采提高了矿山经济效益,保障了矿山绿色、安全开采。
