为评价麻家梁矿煤层受奥陶系岩溶水的影响程度，结合充水含水层充水条件、充水途径，在分析该矿地质和水文地质条件的基础上，介绍了煤层底板含隔水层特征，对底板扰动破坏深度、有效隔水层厚度及可能导水通道进行分析，采用标高比对法、突水系数法、斯氏公式法3种不同方法对主采煤层带压开采情况进行突水危险性评价，对开采煤层底板带压开采安全性进行综合评价，对煤层进行合理分区，提出了奥灰突水判识方法，为矿井防治水工作提供技术指导，确保矿井安全生产。

In order to evaluate the influence of the Ordovician karst water on the coal seam in the Majialiang mine field, combined with the water filling conditions and water filling channels of the water-filled aquifer, based on the analysis of the geological and hydrogeological conditions of the mine, the characteristics of the aquiclude in the coal seam floor were analyzed, and the depth of the floor disturbance failure, the thickness of the effective aquiclude and the possible water-conducting channel were introduced. Three different methods, such as the elevation comparison method, the water inrush coefficient method and the Si 's formula method, were used to evaluate the risk of water inrush in the mining of the main coal seam under pressure. The safety of the mining of the coal seam floor under pressure was comprehensively evaluated, and the coal seam was reasonably divided, and the method of identifying the Ordovician limestone water inrush was proposed. Provide technical guidance for mine water prevention and control work to ensure mine safety production.
