Abstract

The study of groundwater flow from the coal seam floor is critical to safe mining operations in China. We developed a numerical simulation model to describe flood water pathways during mining, using the field conditions present at the no. 4196 west work face in the Panxi longwall coal mine, Shandong Province, China, Groundwater flow analysis revealed unusual values for the failure depth of the coal seam floor. The high ground stress and underground pressure, excavation length, width of working face, poor mechanical properties of aquitards, and expansion of fractures by groundwater infiltration all contribute to groundwater flow into the mine. The modeling results predict the time and longwall locations associated with the maximum likelihood of flood occurrence. Such results can be used by decision makers to improve mine design and safety.

Zusammenfassung

Entwickelt wurde ein numerisches Simulationsmodell zur Beschreibung von während des Abbaubetriebs auftretenden Wasserzuflüssen, und zwar unter Verwendung der realen Bedingungen im Streb Nr. 4196 West der Kohlengrube Panxi, Provinz Shandong, China. Die Analyse der Grundwasserströmung offenbarte ungewöhnliche Werte für die Versagensteufe des Flözliegenden. Hohe Bodenpressung, die Erstreckung des Abbauraums in Verhiebsrichtung, die Breite der Abbaufront, eine geringe mechanische Standfestigkeit der Grundwasserhemmer sowie Kluftöffnung infolge Grundwasserinfiltration tragen zum Grundwasserzufluss zur Grube bei. Als Modellergebnis werden Zeitpunkt und Streb-Lokation von Zuflussereignissen maximaler Wahrscheinlichkeit prognostiziert. Derartige Ergebnisse können von den zuständigen Entscheidungsträgern zur Verbesserung der Bergwerksplanung und zur Erhöhung der Arbeitssicherheit genutzt werden.

Resumen

Hemos desarrollado un modelo de simulación numérica para describir las etapas de la inundación durante la explotación minera, usando las condiciones de campo presentes en la cara de trabajo oeste n° 4196 en la mina de carbón de frente largo Panxi, provincia de Shandong, China. El análisis del flujo de agua subterránea reveló inusuales valores para la profundidad de la falla en el piso de la veta de carbón. El elevado estrés del piso, la presión subterránea, la longitud de la excavación, el ancho de la cara de trabajo, las pobres propiedades mecánicas de los acuitardos y la expansión de fracturas por la infiltración de agua subterránea, contribuyen al flujo de agua subterránea dentro de la mina. Los resultados del modelado predicen el tiempo y los lugares de frente alto asociados con la máxima probabilidad de ocurrencia de inundaciones. Estos resultados pueden ser usados para que los tomadores de decisiones mejoren el diseño de la mina y de la seguridad.

摘要

建立了潘西矿(中国山东)4196西长壁工作面底板突水数值模型,模拟开采期间突水路径的形成及演化过程 。地下水流分析可以揭示煤层底板破坏深度。高地应力与高矿山压力、工作面开采长度、工作面宽度、底板弱透水层力学性能及地下水入渗透引起的原始裂隙扩展等都是影响煤矿突水的重要因素。模拟结果预测了深矿井开采最有可能发生突水时间和突水位置。研究成果有利于决策者改进生产设计和提高生产安全性。
