根据多年来的科研生产实践 ,应用非线性科学理论建立了非线性动力学模型 ,并考察了模型的动力学行为 ,发现煤层底板隔水层力学失稳 (突水 )早期阶段有明显的应力失调现象。利用煤层底板应力、应变监测资料 ,通过非线性动力学模型计算 ,可预测煤层底板突水问题是否发生。
Based on years of scientific research and production practice, a nonlinear dynamics model is established based on nonlinear scientific theory. The dynamic behavior of the model is investigated. It is found that there is a significant stress imbalance in the early stage of mechanical instability (water inrush) phenomenon. Using coal seam floor stress and strain monitoring data, through the nonlinear dynamic model calculation, can predict the coal floor water inrush problem occurs.
