| 摘 要： | 某金矿开采工程属于深部采矿，采矿方法的选择对地压的控制具有极其重要的作用。在对矿区的地质研究分析的基础上，结合三山岛金矿、焦家金矿等当地类似矿山的生产实际，按照当地安监部门的相关规定，确定采用上向进路充填采矿法。通过力学分析、数值模拟等方法，从采矿结构参数、进路充填体及充填作业方面对进路充填采矿法进行了影响因素分析，提出了优化建议。

| Abstract: | The Mining engineering in this deposit belongs to deep mining.Selection of mining methods plays an important role in ground pressure control.Based on geological analysis in this area, combining with the actual production in Sanshandao Gold Mine, Jiaojia Gold Mine and other similar mines, the upward drift stoping with backfill is adopted, according to the relevant provisions of the local safety supervision departments.Through the mechanical analysis and the numerical simulation method, the influential factors on the drift stoping are analyzed from the mining structure parameters, filling materials and filling operation, then some suggestions are put forward. |
