概述为了研究回采工作对岩层活动的影响及确定用废石作局部(50%)充填带对岩层控制和防止岩石崩落是否具有重要的意义,在两个相邻的金矿——布莱弗利济希特和西德利封坦金矿进行了研究。选择这两个矿山,是因为它们的地质条件、开采深度和回采方法相似,并且希望在它们之间只有所用支护方法有着显著的差别,以便进行比较。布莱弗利济希特是应用如图1所示的,用50%废石填心的木垛,作为最大限度地控制顶板,木垛各层的规格为2呎×2呎×7吋,沿
Overview In order to study the impact of the recovery work on the rock activity and to determine whether the local use of waste rock for filling (50%) to control rock formation and prevent rock avalanches is of crucial importance, two adjacent gold mines, Chihpen and West Deli seal gold mine were studied. The two mines were selected because of their geological conditions, depth of extraction and recovery methods, and it is expected that there will be only significant differences between them in the method of support used for comparison. Blair Ricciat is applied as shown in Figure 1, filled with 50% waste rock wood stack, as the maximum control of the roof, wood pallets of various specifications of 2 feet × 2 feet × 7 inches, along
