急倾斜煤层开采沉陷预计研究

Research on Prediction of Mining Subsidence for Steeply inclined Coal Seam

由于沉陷预计常用的方法对于急倾斜煤层开采的沉陷预计具有一定的局限性,预测结果与实测数据相差较大,难以符合实际生产要求。因此,通过比较实测下沉曲线与等效煤层的概率积分法预计曲线,推导出一套适合概率积分法预计的急倾斜煤层开采下沉预计参数,为急倾斜煤层下沉预计工作的简化提供了基础。

Common subsidence prediction method is limited for steeply inclined coal seam, so prediction result with the method is far away from observation data. This paper presents a set of parameters for probability-integral subsidence prediction of steeply inclined coal seam by comparing observing subsidence curve with equivalent probability-integral prediction curve, which form a base for simplification of subsidence prediction for steeply inclined coal seam.
