安太堡露天煤矿水土流失特征与控制

系统研究了安太堡露天煤矿工业广场区，开挖区，待开挖区和排土场的土地扰动时空变化，水土流失危害及其可操作性的控制技术。结果表明；工业广场区水土流失轻微，但粉尘污染严重重点是营造防污染林带；开挖区地面扰动频繁风和重力侵蚀加剧，应注重周边溯源侵和崩塌的防护；待开挖区和与原地貌水土流动相当，应以暂时性水土保持措施为主；而排土场是在重型机械操作下堆置面民的一种大型人工松散堆积体，是矿区水土流失治理的重点。

CHARACTERISTICS OF SOIL EROSION AND ITS CONTROL IN ANTAIBAO OPEN PIT MINE

The disturbed lands development in time and space, harmfulness of soil erosion from mining activity and the practical control techniques in industrial area, excavation area, expected excavation area and dumping site in Antaibao Open Pit Mine were systematically studied. The results show that light degree of soil erosion occurred in industrial area but serious dust pollution, and pollution prevention forest belt should be planted. There are frequent surface disturbance and severe wind erosion and gravity erosion in excavation area, prevention of circumferential retrogressive erosion and devolution should be laid stress on. Soil erosion in expected exavation area is similar to that of original geomorphy, themporary water soil conservation should be given priority to. Dumping site is a large artificial loose pile up by heavy machinery, thus is the priority of harness of soil erosion in mining area.
