摘 要:针对复杂地质条件矿体开采技术难题,通过对矿体产状和工程地质条件进行分析,对复杂地质条件下的采矿方法进行了优化,选择上向进路充填采矿法回采不稳固或中厚至厚大矿体,工业试验结果表明:上向进路充填采矿法适用于复杂地质条件的矿体回采,采矿损失率降至8%、贫化率控制在10%,有效地提高了不稳固矿体回采的安全性和经济效益,吨矿效益达300元以上。Aiming at the mining technical problems of the orebody under complex geological conditions,the mining method under complex geological conditions was optimized by analyzing the occurrence of orebodies and engineering geological conditions,and the upward drift filling mining method was selected to recover unstable or medium thick to thick large orebody.The industrial test results show that the upward drift filling method is suitable for the orebody mining under complex geological conditions,the mining loss rate is reduced to 8%,and the dilution rate is controlled at 10%,which effectively improves the safety and economic benefits of unstable orebody mining,with the benefit of more than 300RMB per ton of ore.
