摘要
以铜川矿区16个地表移动观测站数据为基础,充分考虑了该矿区的实际地质和采矿条件,构建了10个采煤沉陷的控制因素,然后应用灰色关联分析的方法,对这些控制因素对采煤沉陷的"贡献"进行排序,再利用逐步回归的方法对这些控制因素作回归分析,得出的综合结论为:铜川矿区采煤沉陷主要控制因素依次是扰动系数、覆岩综合硬度、表土层厚度、工作面倾向长度、采厚。
On the basis of the observed data obtained from the 16 ground surface movement surveying stations, and fully considering some conditions on geology and mining, the 10 controlling factors of coal mining subsidence were determined. Then these 10 controlling factors were ordered on their contribution to mining subsidence by gray incidence analysis, and were analyzed by stepwise regression analysis. The general conclusion is that the main controlling factors of mining subsidence in Tongchuan mining area are perturbation coefficient, integrated hardness of overburden strata, thickness of surface soil, width of working face and mining thickness in turn.
