| 摘 要： | 某石英砂矿由于受到产品销售问题及周围环境条件的限制，决定采用地下开采方式。矿体南西部已经靠近矿界，为了保证矿体开采过程中的安全，需要在靠近矿界的矿段预留保安矿柱。因此，采用FLAC3D数值模拟软件，对矿体开采留设不同厚度的保安矿柱进行安全稳定性分析及比较，最终确定留设保安矿柱的合理尺寸。

| Abstract: | Due to the limitation of product sales and surrounding environment,underground mining method is adopted in a quartz sand mine.The ore body is close to the ore boundary in the south and west，ensure the safety of the ore body in the process of mining,it is necessary to reserve the safety pillar in the ore section near the ore boundary.Therefore,FLAC3D numerical simulation software was used to analyze and compare the safety and stability of security pillars with different thicknesses for ore body mining,and finally determine the reasonable size of security pillars. |
