露天矿大型排土场水蚀特征及其植被控制效果研究——以安太堡露天煤矿南排土场为例

Research on Water Erosion Characteristics and Its Control Measures in Large Dump of Opencast Coal Mine in Loess Area ——In the Case of the South Dump of ATB Opencast Coal Mine

以山西省平朔露天煤矿安太堡矿南排土场1993～2002年径流小区定位观测为基础,对排土场未复垦、复垦种植2年、复垦种植10年等3个阶段产流产沙特征及其植被措施的减流减沙效果进行分析,初步建立了小区暴雨-产流-产沙经验模型,比较了不同植被及其配置模式的减流减沙效果,并提出了适合的植被与改进措施。

Based on plots experiments of 1993~2002 in the south dump of Antaibu opencast coal mine, the water erosion characteristics and the erosion control profit of vegetations in the 3 stages of newly-constructed, the 2nd year and 10th year of reclamation are analyzed. The empirical models of water and soil erosion are brought forward. The erosion control profits of the vegetation patterns in the plots are compared, and the measures of suitable revegetation and erosion control are proposed and improved.
