文摘Based on the surveying data of strata-moving angle and the ordinary least squares regression,this paper is to construct,a regression model is constructed which is strata-moving parameterβconcerning the coal bed obliquity,coal thickness,mining depth,etc.But the regression is unsuccessful.The result is that none of the parameters is suited,this is not up to objective reality.This paper presents a novel method,partial least squares regression(PLS regression),to construct the statistic model of strata-moving parameterβ.The experiment shows that the forecasting model is reasonable.
