河南省济源市玉川产业聚集区矿山生态环境地质问题及治理对策

Ecological environmental geological problems in industrial agglomeration area of Yuchuan,Jiyuan City,Henan Province and its countermeasures

矿山地质生态环境问题越来越受到国家的重视,其引发的地质灾害一直是制约部分地区发展的瓶颈。以人口较为密集的河南省济源市玉川产业聚集区内的矿山为研究对象,通过资料收集与分析、野外实地调查、综合研究等方法,总结了研究区内比较典型的地质环境问题,即露天采坑、渣堆、废弃石料厂、废弃石灰窑、废弃平硐、采空区、地面塌陷等,并且以比较典型的NJ4′治理区为例,该区内发育地质灾害主要有露天采坑7个、渣堆7处、废弃石料厂4处、废弃石灰窑11座、废弃平硐12处、采空区3处、地面塌陷坑2处。采用“采空区浅部回填,深部地表设置警示牌+高陡边坡上部大坡比放坡回填至坡脚+采坑内挖高填低呈斜坡平整+截排水+道路+覆土植树+灌溉工程”的综合治理对策,为与该地区相似的矿山地质环境问题的治理提供参考。

More and more attention has been paid to the geological and ecological environment problems of mines,and the geological disasters caused by them have always been the bottleneck problem restricting the development of some areas.Taking the mines in Yuchuan industrial cluster area of Jiyuan City,Henan Province as the research object,the typical geological environment problems in the research area were summarized by means of data collection and analysis,field investigation and comprehensive research,including open pit,slag heap,abandoned stone plant,abandoned lime kiln,abandoned adit,goaf,ground collapse,etc.,taking the typical NJ4′treatment area as an example,the geological disasters in this area mainly include 7 open pit,7 slag heap,4 abandoned stone plant,11 abandoned lime kiln,12 abandoned adit,3 goaf and 2 ground collapse pits.The comprehensive control countermeasures of"shallow backfill of goaf,setting warning signs on deep surface+large slope ratio at the upper part of high and steep slope,backfilling to the foot of slope+digging high and filling low in mining pit,slope leveling+interception and drainage+road+covering soil and planting trees+irrigation engineering"were adopted,so as to provide reference for the treatment of similar mine geological environmental problems in this area.
