| 摘 要： | 矿床地下开采时,在没有其他安全措施的情况下,不得不采用预留安全矿柱的方法,以保护地面建筑物、构筑物和主要井巷免受因地下采矿而引起的破坏。但这会导致矿量的损失,故需要寻找合理预留安全矿柱的方法。作者用解析的方法对预留安全矿柱进行研究,突破了常用的传统方法。

| Abstract: | Without other safety measures, some safety ore pillars have to be reserved to prevent the ground buildings and constructs and the main shafts from being damaged during underground mining. It is necessary to find a way to decide a rational reservation of them so as to reduce as much as possible the loss of ore quantity from the reserved pillars. An attempt is made to attack the problem in the way of analysis which breaks away from the traditional one and proves practicable. |
