摘要
为了得到急倾斜薄矿体深井开采岩层移动规律,分析各主要影响因素对岩层移动的影响程度,可运用正交实验分析方法对主要影响因素进行敏感度分析,并将地表最大下沉量及下沉边界范围设为评价参数,能够简单快捷地得出各因素对评价因素的敏感度排序及相关趋势。研究发现,两个评价因素同开采深度、岩体质量水平呈正相关,而同矿体角度水平呈负相关,矿体厚度影响趋势不明显。
In order to get the strata movement law of steep-thin ore in deep mining,and analyze the main factor＇s influence to strata movement,the orthogonal experimental analysis is a good method for the sensitivity analysis of main factors.In addition,maximum Z-Displacement and subsidence boundary can be set as evaluation parameters,then the sensitivity ranking and related tends can be got rapidly.The research shows that,the two evaluation factors are positively correlated with the mining depth and the rock mass quality,negatively correlated with dip angle of ore body,but the ore body thickness isn＇t correlated with evaluation factors obviously.
