综放条件下上覆岩层“两带”高度多因素经验公式确定

Determination on multiple factors empirical formula of “two zone” Height in overburden strata under fully mechanized top coal caving mining

通过收集国内多个综放工作面的"两带"高度数据,利用多元回归分析的方法,得到综放开采条件下的"两带"高度计算经验公式,并进行适用性分析。

With the collection on the ＂two zone＂heights information in the domestic several fully mechanized top coal caving miming faces,the experiment formula of the＂two zone＂height in the fully mechanized top coal caving mining face was summarized by using the method of multiple regression analysis.And the applicability analysis is carried out.
