基于Fisher判别的煤层底板突水量预测研究

Study on Forecast of Water Bursting Volume from Coal Seam Floor Based on Fisher Discriminant

针对煤层底板突水的主要影响因素,综合考虑水源、水压、隔水层、底板采动导水断裂带深度、断层等因素的影响,基于Fisher判别分析理论,利用国内一些采煤工作面底板突水资料作为训练样本,建立了煤层底板突水预测的距离判别分析模型。工程应用表明,该模型结果与实际情况吻合良好,说明该模型在煤层底板突水预测中具有良好的实用性和有效性。

Considering the factors influencing water bursting from coal seam floor, such as water source, water pressure, water - resisting layer, the depth of water - conducting floor fracture zone brought by mining, fault, and so on, using the data about water bursting from coal seam floor in some coal mining face in China as the training sample, based on the theory of Fisher Discriminant analysis, a distance discriminant analysis model for the forecasting of water bursting from coal seam floor. The application of the model in engineering indicated that the results obtained by it is better in accordance with the practice, it is practical and effective in forecasting water bursting from coal seam floor.
