摘要： 为了更准确地评估北辛窑煤矿6^#煤层底板突水的危险性，在充分考虑井田水文地质条件和区域构造位置的基
础上，采用五图-双系数三级判别法对6^#煤层底板奥灰水突水危险性实行分区评估，以确保带压安全开采，为煤层安全
开采提供技术支撑，也便于更深刻地认识煤矿安全生产指导工作的重要性。五图-双系数三级判别法是一种有效的方法，
可以用来评估底板突水的危险性。

Abstract: In order to more accurately evaluate the harmfulness of water inrush from the floor of No.6 coal seam in Beixinyao
Coal Mine, the five-figure double-coefficient three-level discriminant method was adopted to assess the harmfulness of Ordovician
limestone water inrush from the floor of No.6 coal seam in different areas, so as to ensure safe mining under pressure and provide
technical support for safe mining of coal seams, facilitate a deeper understanding of the importance of coal mine safety production
guidance work. The five-figure double-coefficient three-level discriminant method is an effective method, which can be used to
evaluate the risk of water inrush from the floor.

 Key words: coal mine; five-figure double-coefficient three-level discriminant method; floor water inrush; risk assessment;
