摘　　要：双柳煤矿4号煤层存在底板太灰水带压开采问题,文中在概述井田内太灰水贮存特征的基础上,分别利用突水系数法和多层叠加抗压强度比值系数法进行了太灰水对4号煤层突水危险性评价,最后叠置二者评价结果做出了综合评价。以期为煤矿防治水工作提供参考依据。Shuangliu coal sing the water Taiyuan group tion results to work. The No. 4 coal seam has the problem of mining with Taiyuan group limestone karst water pressure in mine, according to Taiyuan group limestone karst water storage features in mining area, respectively u- inrush coefficient method and multilayer superposition compressive strength ratio coefficient method, the limestone karst water bursting hazard on the No. 4 coal seam was evaluated, finally stacking two evalua- make comprehensive assessment. In order to provide reference for mine water prevention and control
