摘要
通过总结庙沟铁矿矿山开采现状及排土场现状,提出由于岩土堆存带来的地质环境问题。从地形地貌、地层岩性组成及岩石物理力学性质等4个方面分析该区工程地质特征,同时阐述区内水文地质概况。在采用钻探、原位测试进行野外地质观察和分析该区周边岩体节理特征的基础上,确定排土场稳定性计算剖面并选取计算参数,通过进行东排土场稳定性计算,提出东排土场治理具体措施,并从社会、环境和经济等3个方面进行排土场治理综合效益预测。
By summarizing mining status and the dump situation of MiaoGou iron mine, the geological environment problems resulting from the geoteehnieal stockpiling are put forward. From four aspects of landform, stratigraphic lithology composition and rock area physical and mechanical properties, the engineering geological characteristics are analyzes, and the zone hydrogeologieal situation are described as well. Based on the field geological investigation by drilling and in situ tests and analysis on the characteristics of the surrounding rock joints, the dump stability calculation profile are determined and the parameters are selected. Through the calculation on stability of the estem dump, the paper proposed specific measures to treat dumps from social, environmental and economic aspects and forecast comprehensive benefit of dump governance.
