摘要:
[目的]探索废弃采石矿山生态环境恢复治理模式及治理成本,为陕西省韩城市西山一带其余废弃采石矿山和煤矿山的生态环境恢复治理提供借鉴。[方法]通过现场调查、勘探及室内试验,分析韩城市西塬废弃采石矿山的环境地质问题,即采石不稳定边坡地质结构及变形破坏特征与废弃渣石占用耕地及泥流等问题。[结果]提出采石不稳定边坡与废渣的工程治理及生态恢复治理方案。采石不稳定边坡选用削方压脚与坡面植被混凝土技术,植面的植被类型应耐旱、耐寒和耐贫瘠;废弃渣石以挖高填低与分级填筑压实,坡脚修筑挡墙,坡面覆盖土壤并栽植乔灌花草等进行环境恢复治理。[结论]研究区的采石不稳定边坡和矿区堆积废渣应采用“削高填低”的工程治理方案,坡面采用植被技术的生态环境恢复治理方案。

Abstract:
[Objective] Exploring the restoration control model and control cost of ecological environment in abandoned quarryes, which can provide references for the environmental restoration and management of the remaining quarrying mines in Xishan, Hancheng City of Shaanxi Province.[Methods] Through the investigation, exploration and indoor experiment, the geological environment of the abandoned rock quarrying in the west of Hancheng City was analyzed, which is exposed rock slope deformation characteristics, waste slag occupation of arable land and mud and other issues.[Results] The paper put forward engineering treatment and ecological restoration treatment of slope and waste slag. Ways of skiving the top and heaving foot, vegetating the concrete into the slope were adopted. Wasted slag was used to dig the high place, fill the low place, and fill compaction by grades, to bulid retaining walls on the slope foot, cover the slide with soil and planting flowers. Trees had a advance for environmental governance.[Conclusion] The engineering treatment with "dig the high place and fill the low place" for the unstable slope and the accumulated waste slag, and covering the slide surface with the vegetation technology have a advance for ecological environmental governance.
