摘要
运用灰色关联分析法分析了榆神府矿区煤炭赋存条件和开采设计方面7个重要因素对矿区开采沉陷损害程度的影响。关联度分析结果表明,这7因素与开采沉陷损害程度的关联序是:扰动系数>宽深比>覆岩综合普氏硬度>下沉系数>深厚比>煤层倾角>初长比。希望从煤炭赋存条件和开采设计的角度出发,为煤矿区内的开采沉陷损害控制和评价提供科学依据。
The grey corrclative analysis method is used to analyze the influences of 7 important factors of coal existent condition and mining design on mining subsidence damage grade. The results show that： the order of correlative degree of mining subsidence damage grade and 7 factors is： perturbation ceefficient 〉 width - depth ratio 〉 synthetical Protodyakonov coefficient of overburden rocks 〉 subsidence factor 〉 the ratio of mining depth and heist 〉 coal seam dip angle 〉 preliminary mining area to actual mining area ratio. It is hoped that the paper gives a reference to mining subsidence damage grade control and assessment in coal area.
