贵州省遵义长沟锰矿排渣场边坡环境治理

Discussion on Slope Environmental Treatment Technology of Slag Dump of Changgou Manganese Mine in Zunyi,Guizhou Province

长沟锰矿沙坝矿段目前使用的菜子湾渣场位于湘江河边,渣场接近最大容量,该渣场存在发生严重崩塌、滑坡、溃坝等安全隐患。矿山通过对渣库边坡治理及生态环境恢复,及时消除排渣场安全隐患,同时对渣坡回填覆盖土壤,引入先进的喷播技术,以桂花、刺槐、黑麦草、苦葛藤、爬山虎等相结合,逐步将渣场植被过渡为稳定的生态群落,从而达到良好的治理效果。

The Caiziwan slag disposal site currently used in Shaba ore section of Changgou Manganese Mine is located by the Xiangjiang River, and the reservoir capacity is nearing the end. The inventory has potential safety hazards such as serious collapse, landslide, and dam break. Through the treatment of the side slope of the slag pond and the restoration of the ecological environment, the mine timely eliminated the potential safety hazards in the slag disposal area. At the same time, the slag slope was backfilled and covered with soil, and advanced spray seeding technology was introduced. With the combination of osmanthus, locust, ryegrass, kudzu vine, and creeper, the mine gradually transformed the vegetation in the slag disposal area into a stable ecological community, which is to achieve the treatment effect.
