摘要
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。
To investigate the development of maximum mining height of longwalls in China, a GM ( 1,1 ) and linear regression combined model was employed to predict the maximum mining height. Multiple linear regression and stepwise regression were used to investigate the influence of these factors to mining height. It is unveiled that a significant linear correlation is existed between mining height and five influencing factors, rated working resistance of shields and total installed power of the shearer are the most important factors that control the increase of mininz height.
