| 摘 要： | 为解决金山店铁矿地下矿体崩落开采时地表塌陷区的安全回填问题，利用相似原理对相似模型进行了崩落采矿模拟试验，找出了不同分段落矿时地表回填体的塌陷模式并进行了分析。试验结果表明地表回填体最活跃的区域处于端部出矿口的正上方，这就为确定回填时的重点防范区域与指导塌陷区安全回填工作提供了必要的科学依据。

| Abstract: | In order to solve the safety backfilling problem of surface subsidence about underground ore-body caving mining in Jinshandian Iron Ore, the similarity principle is adopted to make similar model for the simulation test of caving. The collapse mode and impact analysis of surface backfill while mining at different section are found out. The tests show that the most active area of surface backfill is right above the drawing outlet. It provides necessary scientific basis to determine the key prevention area as backfilling and guide the safety backfilling of subsidence area. |
