| 摘 要： | 三道庄钼钨矿床是一特大型矿床,多年来由于无序开采,形成大量形态复杂的地下采空区群,严重影响和威胁矿区的正常生产,本文运用岩体的物理力学性质初步建立了采空区安全分类标准,采用普氏地压法、传统半定量法等理论方法,计算了采空区顶板的最小安全厚度,探讨了采空区的塌陷破坏模式,为采空区治理提供了科学依据.

| Abstract: | Molybdenum and tungsten deposit is a super--large scale one. However, it has been turned largely into complicated underground empty quarry zones owing to the improper and illogical exploitation for years. It therefore has a severe and threatening effect on the safe production. The paper offers a scientific reference to harnessing the empty quarry zones through primarily setting up safe standards of classifying zones according to the rock physical attribution. It has adopted advanced theoretical approaches such as Pushi geostatic approach, and traditional semi--quantitative approach to calculate the minimum safety value of the ceiling planks and to study the cave-in and destructive mode. |
