Probing Research on Runoff-dispersing Erosion Control Pattern and its Design in Large Dump in the Case of the Dump of Antaibu Opencast Coal Mine in Shanxi Province
Abstract：Based on the 16 years' practice of soil and water conservation in the dump of Antaibu opencast mine, the water erosion control measures of large dump are studied, and the runoff-dispersing erosion control pattern is put forward. The pattern divided the whole dump into many runoff-dispersing units, and the runoff resulting from storm can be dispersed evenly. Thus the water erosion is under control and the large quantity of runoff flowing into the fissures will not occur. At the same time, the measures of runoff regulation and proper vegetation in each unit are also taken. Besides, drainage ditches in key influx routes are built to prevention of the flood caused by runoff-dispersing units destroyed under the condition of severe storm. Further, based on the plots experiments and vegetation investigation in 1993—2002, the typical unit and its vegetation pattern in the dump are designed preliminarily. This runoff-dispersing pattern, which is of good maneuverability, can not only control the dump water erosion effectively, but also can help to establish vegetation as soon as possible.
