基于采掘揭露资料、钻孔资料、水位观测数据和抽水试验成果，对研究区构造复杂程度和奥灰水文地质条件展开研究，并采用安全水头值法、安全隔水层厚度法和突水系数法对奥灰水带压开采突水危险性进行了综合评价。结果表明：研究区下部12＃煤层开采掘进巷道基本不具突水危险；而当矿井生产延伸至深部水平时，研究区西北翼构造复杂块段12＃煤层回采工作面将面临突水威胁，届时需提前开展探水、防水工作。

Based on the data of exploration,borehole,water level observation and pumping test results,research on the tectonic complexity and hydrogeological conditions of Ordovician limestone water in the research area was carried out?? Water inrush risk on mining under pressure of Ordovician limestone water was evaluated synthetically by secure hydraulic head method,safe aquifuge thickness method and water bursting coefficient method?? The results showed that it was generally safe in the mining and excavation roadway of No??12 coal seam?? Nevertheless,the working face of No??12 coal seam in the complex structure block located the northwest of research area would be faced with water inrush threat when the mining area extended to the deep level,so water detection and prevention work should be carried out in advance.
