摘要
对云南省缓倾斜多层某磷矿提出了机械化房柱采矿法的研究,并通过对房柱法中点柱尺寸的选择进行了数值模拟,从岩体应力状态及塑性区分布结果分析得出,4.5m×4.5m的点矿柱稳定性具有可靠性。
The mechanized room-and-pillar stoping is proposed for gently inclined multilayer phosphate ore body, the numerical modeling for the pillar size of this mining method was carried out, the analysis of the stress status and plastic distribution characteristics of rock masses shows that the stability of 4. 5m ×4. 5m pillar is reliable.
