本文针对岩溶煤矿矿井煤层底板突水系统动力学行为的复杂性，采用近年发展起来的相空间重构方法，计算了该类复杂系统吸引子的关联维，据此对煤层底板突水行为进行了分析、预测，并用生产实践证明预测的正确性。
In this paper, according to the complexity of dynamic behavior of coal floor water inrush system in karst coal mines, the phase dimension reconstruction method developed in recent years is used to calculate the correlation dimension of attractors in this complex system. Based on this, Analysis, forecast, and production practice to prove the correctness of the forecast.
