摘要
豫南某地露天矿山排土场地属低山丘陵区,场地南侧高北侧低,整体高差为59 m。由于堆积范围大,北侧顺坡排土易形成松散高陡边坡,可能发生滑坡地质灾害。该排土场分级修建七次拦渣坝,结合边坡防护及截排水等工程措施,保证弃土场的稳定性。
The spoil dump site of an open-pit mine in southern Henan belongs to the low hill area.The site is higher in the south and lower in the north,with an overall height difference of 59 m.Due to the large accumulation range,the loose and steep side slope of the spoil dump is easily formed in the north following the slope,which may lead to landslide geological disasters.The spoil dump site has built seven retaining dams in stages,combined with slope protection,interception and drainage and other engineering measures to ensure the stability of the spoil dump site.
