为研究大采高综采工作面在我国的发展趋势,提出了GM(1,1)和线性回归组合模型,对我国厚煤层大采高综采工作面采高进行了预测。通过多元线性回归模型和逐步回归分析模型分析得出:采高与5个影响因素之间线性关系显著,支架工作阻力和采煤机装机功率的提高是采高增长的主要因素。
In order to study the development trend of the fully mechanized coal mining face in our country, this paper proposed a combined model of GM (1,1) and linear regression to predict the height of the fully mechanized high and full mechanized mining face in thick coal seam in China. The result of multivariate linear regression model and stepwise regression analysis shows that there is a significant linear relationship between the mining height and the five influencing factors. The increase of working resistance and the installed power of shearer is the main factor of high growth.
