重庆某矿开采过程中岩层移动的分形特征及其预测

Fractal Characteristic and Forecasting of Rock Strata Movement for A Mine in Chongqing

用分形插值方法分析重庆某矿开采过程中的岩层移动特征,并探讨其预测方法。实测岩层下沉量和水平移动量的非线性统计分析表明,下沉量和水平移动量等岩层移动特征值具有统计分形特征。下沉量和水平移动量的分形插值拟合曲线与实测岩移数据吻合较好。

The characteristic of rock strata movement in mining process of a mine in Chongqing is analyzed by fractal regressive method, and the forecasting of the movement is considered. It is indicated by the nonlinear statistics analysis of the observational data of the rock strata subsidence and horizontal movement that the subsidence and horizontal movement of this mine is featured with fractal characteristic. The fractal interpolating fitting curves are well consonant with the observation data.
