摘要
矿山创面高陡边坡是矿山地质环境治理与生态修复的难点。该文选取四川都江堰白依庵泥岩矿高陡边坡为研究对象,通过野外矿山地质环境详细调查,认为边坡失稳、滑坡灾害和创面边坡大面积裸露制约白依庵泥岩矿安全生产和环境保护的主要问题。识别出2处创面边坡滑坡,其中Ⅰ#滑坡堆积区岩土体处于欠稳定-稳定状态,Ⅱ#滑坡当前经历过整体失稳滑移,目前处于基本稳定-欠稳定状态。基于生态自循环理念,在创面边坡构建合理的土壤结构,以生态修复措施协助自然生态恢复。将创面边坡分为破碎岩面、完整岩面和滑坡面三种类型,根据泥岩面的特点分布设计生态修复方案和工艺流程。
The high and steep slopes of mines are a difficult point in mine geological environment management and ecological restoration.This paper selects the high and steep slope of Baiyian Mudstone Mine in Dujiangyan City as the research object.Through detailed investigation of the geological environment of the field mine,it is believed that slope instability,landslide disasters and largearea exposure of wound slopes are the main problems restricting the safe production and environmental protection of Baiyian Mudstone Mine.We identified two wound side slope landslides.Among them,the rock and soil mass in the landslide accumulation area ofⅠ#landslide is in an under-stable-stable state,and theⅡ#landslide has experienced an overall instability slip and is currently in a basically stable-under-stable state.Based on the concept of ecological self-circulation,a reasonable soil structure is built on the slope,and ecological restoration measures are used to assist natural ecological restoration.The slope is divided into three types:broken rock face,complete rock face and landslide face,and the ecological restoration plan and process flow are designed according to the characteristic distribution of mudstone rock face.
