根据陕西榆神府矿区15个典型矿点的煤炭地质赋存条件和开采设计以及地表岩移观测数据,采用灰色关联分析法研究了地表最大下沉系数与其影响因素之间的关系,分析结果表明:覆岩综合普氏硬度、扰动系数、深厚比、采高等是影响该矿区开采沉陷的关键影响因子;用逐步回归分析方法,建立了开采沉陷回归方程,对煤矿区开采沉陷的采前预计提供了科学依据。
According to coal geological storage conditions and mining design and surface rock displacement observation data of 15 typical ore points in Yushenfu mining area of Shaanxi Province, the relationship between the maximum subsidence coefficient and its influencing factors was studied by gray relational analysis method. The results show that : The comprehensive overburden hardness, perturbation coefficient, deep ratio and mining height are the key influencing factors of mining subsidence in this mining area. By using stepwise regression analysis method, the mining subsidence regression equation is established, and the mining subsidence is expected to be provided before mining The scientific basis.
