中文摘要：
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.
英文摘要：
The water inrush of coal seam floor is the main cause of the coal mines＇accidents in North China.Based on the geological conditions of Fei-Cheng Coal Mines as well as the software of FLAC3D and eletrolyte servosystem of rock mechanics,further research was made that on the lawof moving and deformation of mining seams and on the permeability of the rock ores and on the deformation damage of rocks.The principle was analysized,that of the water inrush in mining seams on the water body.It is significant to establish the basis of the safe mining technology and technique in the coal seams on the water body.
