| 摘 要： | 采煤塌陷地预测对于矿区土地复垦具有重要意义,是矿区损毁土地复垦工作的基础,对于确保土地复垦方案科学性、准确性及合理性起决定性作用。采煤塌陷地预测一般仅考虑开采计划和地质特点,未考虑矿区原始地形的影响,预测结果往往无法准确反映矿区地表沉陷情况。以我国东部某煤矿为研究对象,通过对矿区原始地形、采煤沉陷区DEM进行融合,获得考虑原始地形的采煤沉陷区,通过计算并提取坡度、地表起伏度、积水面积地形因子,分析矿区原始地形对采煤沉陷区地形特征的影响。研究表明:考虑矿区原始地形后的采煤沉陷区地形特征发生了明显变化,沉陷区地形坡度、地表起伏度明显增大,积水面积明显减少,采煤沉陷区损毁土地地形特征更加准确、真实。分析结果可为矿区开采沉陷预测和损毁土地复垦治理提供可靠依据。
