【Abstract】 To prevent a mine inrush water from a first coal mining face of a new mine, a prediction and forecast is key. The paper considered that base on the rock analysis of the surrounding rock structure, a rational high "two zone" experience formula, a theoretical formula for mine floor failure depth, a finite element analysis method for change in mine water flow, a prediction of the face roof and floor failure and a prevention of failed rock expanding into a high water bearing zone are the effective methods to prevent mine water inrush from the first coal mining face. Also the authors considered that the calculated inrush water quantity and the measured results shown an analogue method more close to the actual condition than a hydrogeological calculation method in a prediction of mine inrush water at the present conditions.更多还原
