摘要
通过对黑岱沟露天煤矿排土场边坡多项治理措施的试验研究,确定排土场边坡治理的有效措施为:排土场边坡构筑时修筑挡水埂,阻止平台径流汇入边坡,坡脚堆放大石块,拦截坡面下移泥沙;排土场边坡采用径流分散的方法减少排土场水蚀和水的大量损失;排土场边坡植被配置模式从现状实施效果分析主要有沙棘护坡模式、山杏-沙棘-柠条护坡模式和紫穗槐-柠条-紫花苜蓿护坡模式3种。
Through on experimental investigation of control measure on spoil dump slope of Heidaigou strip mine,identify effective measures on spoil dump,build water-retaining terrace at spoil dump slope preventing runoff form platform entering slope,stacked stones at slope side,blocking sediment of downmovement on spoil,use dispersed runoff method at the spoil dump,reduce water erosion and water loss of spoil dump. According to existing effect analysis,there are three primary pattern to plant configuration pattern of spoil dump,Hippophae rhamnoides L protect slope pattern,Armeniaca sibirica( L.) LamHippophae rhamnoides L-Caragana microphylla( Pall.) Lam protect slope pattern, and Amorpha fruticosa L.-Caragana microphylla( Pall.) Lam-Medicago sativa L protect slope pattern.
