Abstract
Based on the analysis and study of hydrogeological conditions and main influencing factors of mine water inrush,the mine field structure is undeveloped and water insulation of coal floor water-resisting layer performance is better.Water bursting coefficient method is used to evaluate coal floor Ordovician limestone water inrush risk,and the study finds that the water bursting coefficients of 8# and 11# coal seam floor are less than the critical value;it can realize safe mining under the condition of unconcealed water conducted fault or water flowing subsided column and other water conducting structures.According to the characteristics of Ordovician limestone water inrush,this paper proposes some control measures such as integrating geophysical prospecting with drilling exploration for heading face and mining face,strengthening the safety measures including early warning system of mine water monitoring,waterproof and drainage system and emergency rescue,etc.关键词
