摘要

本文主要在從地質構造、礦脈深度、岩石性質、岩體分類及採礦方式等資料，從事東部聯峰礦場傾斜層狀白雲石之地下坑室穩定監測試驗，以聯峰礦場進行監測大地應力對抗室力學分析之研究，俾在該條件下，尋求維護地下坑室之穩定，减少災變之發生並求取最佳之開挖方法，達到開發地下資源之目的。

The in-situ measuring equipment had been established and the measurements were carried out in the underground stope roofs and the surface of the pillar walls for investigating the deformations and the field stress in the stope roofs and the walls in Liang-Fang underground quarry mines. The equipment used consisted of the convex-type extensometers, the convergence meters, the sonic probe extensometers and the vibrating wire stress meters. The measured data of all stations from all the equipment were collected and analysed, and the results of the stress on pillar and the fractured zone on walls of the measuring points were figured out also. The data of the displacement of the borehole extensometer implies the pillar movement toward the North.
