煤层底板突水是华北区域煤矿事故的最主要原因.基于肥城矿区地质条件,应用FLAC3D软件和岩石力学电液伺服系统分别对开采煤层下伏岩层移动变形规律、岩体的渗透特性、岩体在渗流场作用下的变形破坏特征等方面进行了深入研究,分析了水体上煤层开采突水机理,为确定高突危险水体上煤层的安全开采技术与工艺奠定了理论基础,具有十分重要和深远的意义.
Coal seam floor water inrush is the most important reason of coal mine accidents in North China.Based on the geological conditions in Feicheng Mining Area, FLAC3D software and rock mechanics electro-hydraulic servo system are used to study the movement and deformation of underlying rock strata, the permeability of rock mass, The deformation and failure characteristics under the seepage field and so on. The mechanism of water inrush from coal seam mining is analyzed, which lays a theoretical foundation for determining the safe mining technology and technology of coal seam on the high water hazard. It is very important and far-reaching significance.
