Abstract: The main factors of water inrush in mine are the lithological characters of rock beds,distance between layers,geological structure,water pressure and mining actions The distribution of water inrush points is controlled by the geological conditions such as the above three former factors After studying and discussing the geological and tectonic conditions relative to the water inrush in Yanmazhuang field of Jiaozuo coal mine area,the authors predicted the water inrushes which may arise in this field in the future And this prediction will be of great importance for the engineering project,construction and production of coal mine.
