摘要
以光纤Bragg光栅位移传感器对淮北朱仙庄煤矿顶板离层监测为实际数据依据, 选择最佳的典型函数模型对顶板离层进行非线性回归分析, 得出能够反映位移发展趋势的回归曲线。监测结果与回归拟合数据表明: 非线性回归分析预测方法不仅可以反映煤矿顶板离层实时变化过程, 还能根据其变化趋势进行巷道稳定性判断。
Abstract
Base on the actual data from fiber Bragg grating shift sensor of Huaibei Zhuxianzhuang Mine roof abscission layer, the best typical functional model is chosen and a nonlinear regression analysis is made for the roof abscission layer. Therefore a regression curve that can reflect the development tendency of the shift is obtained. Monitoring results and regression data show that nonlinear regression analysis can not only reflect real-time change of roof abscission layer, but also determine the tunnel stability based on the trends.
