摘要
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 their researches and practice, the authors applied nonlinear theory to set up an nonlinear dynamic model, and investigated the dynamic behaviors of the model. It is discoved that there is obvious stress dislocation phenomenon in the early stage of the destabilization (or water invasion) of coal seam floor. Accordingly, on the basis of the monitoring data to the changes of the stress and strain of seam floor, and by applying the nonlinear dynamic model, it is possible to forecast the water invasion.
