水渗流对薄层复合顶板的弱化影响
Weaken influence of water seepage on thin-layer compound roof
摘要
Abstract
Combined with 17# roof of Dongrong 2nd mine, the numerical simulation software of Flac is used to analyze the excavation of roadway, research on weaken influence of water seepage on thin-layer compound roof. The conclusions are as follow; bearing mechanical properties of rock mass structure of thin-layer compound roof have reduced quikly after the water seepage, the deformation speed of the roadway keeps up, eventually lead to thin-layer compound roof take fell and separation caving. It is of important role for the roof support program and accident prevention for this and other mine' s roof like Dongrong 2nd mine.关键词
