老采空区地表沉降监测工程实践与资料分析

The Ground Settlement Moitoring of Engineering Practice and Data Analysis in Old Goaf

针对老采空区地表沉降的不确定性,通过监测方案的设计与实施,采集数据预处理对某一矿区进行分析,利用surfer软件得到了六个监测点的三维线框图并进行渲染。对监测工程资料进行平差处理,得到了各个观测量的精度指标。针对变形监测数据的变化特点,使用AR(p)模型进行编程,主要依据时间序列分析的建模步骤,将建模步骤中的数学公式转换为MATLAB编程语言然后使用编写的程序对变形观测数据进行分析,用前面多期监测数据建立数学模型,并对后面几期进行沉降预测,同时与实测值进行比较分析,用以检验时间序列预测的准确性。

According to the uncertainty of surface settlement in the old goaf,through the design and implementation of monitoring program,the acquisition data preprocessing analyzes a mining area,and the 3- d linear software is used to get the block diagram of six monitoring points and render. The accuracy of each observatioment of monitoring engineering data. According to the change characteristics of deformation monitoring data, using ar （p ） model,the mathematical formula in the modeling steps is converted into MATLAB programming language and deformation observation data, the mathematical model s established by the previous multi-period monitoring data, and the settlement prediction is compared and analyzed to verify the accuracy of time series prediction.
