摘要
陕西省韩城市西山灰岩群采区矿山地质环境问题主要为岩质高陡边坡寸草不生影响地貌景观,可能引发崩塌灾害;废渣占用或破坏土地资源,可能引发泥石流灾害;灰岩石料加工等人类工程活动粉尘污染极为严重,造成附近村民"脏、乱、差"的生活环境。这些矿山地质环境问题属历史遗留下的或责任主体不明,属韩城市"三区两线"矿山覆绿范畴。在充分收集西山灰岩群采区地质资料的基础上,通过详细的外业调查,分析研究区内矿山地质问题及危害,划分了8个恢复治理分区。提出了以植被混凝土喷涂边坡、挖高填低整理采坑并种植花椒树、修筑挡墙拦挡废渣、修筑排水沟疏导地表水等防治措施。治理工程的实施可从根本上改变韩城市西山群采区的地貌景观,提高城市形象,变废为宝,让灰岩群采区成花椒种植基地,为陕西省灰岩矿山地质环境问题恢复治理提供示范和依据。
It is the main geo-environment problem of limestone mining in Western Hills of Han Cheng city,that nothing growing in the high and steep side slope destroys geomorphologic landscape and may cause collapse disasters,waste residue occupying land resources may cause debris flow disasters,and processing stone products causing serious dust pollution deteriorate the living environment of nearby village.Liability subject for these geo-environment problem is promiscuous because of factors left from history,and it belongs to areas of three area and two lines mine return green of Han Cheng city.Based on gathering geological data of limestone mining in Western Hills and field investigations,this paper analyzes geo-environment problem of limestone mining in Western Hills and its hazard to divide the area into 8 protection zones.Control measures also are proposed such as spraying the slope with vegetation concrete,planting pepper on arranged pit,building retaining wall for waste residue,putting up drainage ditch for surface water and so on.These projects of management fundamentally change the geomorphologic landscape of limestone mining in Western Hills,improve city image,recycle waste material,turn the limestone mining into pepper planting base and set an example for geological environment protection of limestone mining in Shannxi Province.
