| 摘 要： | 以东北煤矿区现场所获得的大量实测资料为依据，分析研究了地表下沉系数与覆岩岩性、开采深度、采动性质、采煤方法及顶板管理方法等影响因素之间的变化规律，建立起了其统计关系，并对参数的置信区间进行了估算。所得结果对矿区地表移动与变形预测参数的选取具有重要参考价值。

| Abstract: | Based on a lot of practical surveying data obtained from the North-east coal mining area, the regular pattern of surface subsidence coefficient and its influence factors such as overburden characteristic, mining depth, mining times, mining method, roof control method and so on have been researched. The correlation between subsidence coefficient and its influence factors has been established. In correlation analysis, the confidence interval of subsidence coefficient is estimated by student-distribution. The results have important reference value for the parameter selection in surface movement and deformation forecast caused by underground coal mining. |
