Abstract	Inrush of Ordovician limestone karst water through the mine floor occurs frequently in the Carboniferous-Permian coalfield in northern China. A probability index method was proposed to predict water inrushes using five indices: an aquifer water-bearing index, a structural index, an aquifuge index, an aquifer water pressure index, and an underground pressure index. Expert input was used to obtain weights for these five factors. Expert evaluation and statistical probability were then used to determine weights of the subsidiary factors, allowing the calculation of a water inrush probability index (I) and a threshold water inrush value for the Feicheng coalfield of 0.65. The Dempster-Shafer evidence theory was then used to determine a 74% degree of confidence for this prediction. Finally, the method was applied to the No. 9901 working face of the Taoyang coal mine. A subsequent 1,083 m$^{3}$/h water inrush that occurred there aligned with the statistical results.煤层底板奥陶系岩溶水突水是中国华北石炭-二叠纪煤田的主要煤矿水害类型。提出了一种包含含水层富水性指数、构造指数、隔水层指数、含水层水压指数和矿山压力指数的底板突水概率预测模型。通过专家打分法确定突水概率模型中五个指标的权重,采用专家评价和概率统计法获取次级指标的权重。肥城煤田突水概率指数临界值为0.65,Dempster-Shafer法证明该预测可信度为74%。底板突水概率预测模型应用于肥城煤田陶阳煤矿9901工作面底板突水预测,工作面开采期间突水量达1,083 m$^{3}$/h,预测与实际揭露结果一致。Über die Grubenbausohle stattfindende Karstwassereinbrüche aus ordovizischen Kalksteinen sind im permokarbonischen Kohlerevier Nordchinas ein häufig auftretendes Phänomen. Zur Vorhersage von Einbruchsereignissen wird eine Wahrscheinlichkeitsindex-Methode vorgeschlagen, die auf fünf Einzelindizes beruht: Index der Grundwasserführung, Strukturindex, Grundwasserstauerindex, Grundwasserdruckindex, Gebirgsdruckindex. Die Ableitung der Wichtungsfaktoren der fünf Faktoren erfolgte anhand von Expertenschätzungen. Die Gewichtung weiterer sekundärer Faktoren wurde auf Basis von Sachverständigenbeurteilungen und statistischen Wahrscheinlichkeiten abgeleitet. Im Anschluss erfolgte die Berechnung des Wassereinbruchswahrscheinlichkeitsindex (I) und eines Wassereinbruchschwellenwerts für das Feicheng-Kohlerevier in Höhe von 0,65. Auf Basis der Dempster-Shafer-Theorie wurde für diese Vorhersage ein Zuverlässigkeitsgrad von 74 % ermittelt. Abschließend wurde die Methode für den Abbaustoß No. 9901 in der Taoyang-Kohlengrube angewandt. Ein nachfolgendes Wassereinbruchsereignis mit einem Zulauf von 1083 m$^{3}$/h befand sich in Übereinstimmung mit den statistischen Ergebnissen.Translator: Michael PaulEs frecuente la irrupción de agua a través de la caliza cárstica Ordovícica del piso de mina en el campo de carbón carbonífero-pérmico en el norte de China. Se propuso un método de índice de probabilidad para predicir las irrupciones de agua, usando cinco índices: un índice del contenido de agua en el acuífero, un índice estructural, un índice acuífugo, un índice de la presión de agua en el acuífero y un índice de presión subterránea. La opinión experta se utilizó para obtener los pesos de los cinco factores. La evaluación por expertos y la probabilidad estadística fueron usado para determinar los pesos de los factores subsidiarios, permitiendo el cálculo de un {inidce de probabilidad de irrupción de agua (I) y un valor límite para la irrupción de agua para el campo de carbón Feicheng de 0,65. La teoría Dempster-Shafer determinó 74% de grado de confianza en esta predicción. Finalmente el método fue aplicado a la cara de trabajo N° 9901 de la mina de carbón Taoyang. Una irrupción de agua de 1,083 m3/h que ocurrió posteriormente se ajustó a los resultados estadísticos.
