摘要
经过多年生产经营后的煤矿矿井都会发生不同程度的位移和变形,而帷幕注浆是治理矿井及其周围地表位移和变形的有效方法之一。通过对帷幕注浆的主井及其附近地表实施的变形监测,对不同监测点的不同时间间隔序列进行分析,发现采用平均时间间隔序列建立的模型其预报精度等级和预报准确率均为最优。
Some displacements and deformations for the mine Curtain grouting is one of efficient methods for protecting the shaft shaft working over past many years＇ may occur. and the surface around the shaft from the harm. The deformation caused by grouting around mine shaft is monitored with a reasonable scheme and the measured data are processed with the time-series theory to analyze and forecast the dangerous deformation. Through analyzing different time series at different monitoring points, it is found out that the degree of forecasting precision and the accuracy ratio of forecasting model established with mean-interval time-series are best .
