唐河县水泥厂废弃矿山地质环境特征与治理恢复探索

通过调查露天开采的废弃大理岩矿山,明确得出:矿区现有63个采坑,18处高陡边坡,3处废弃渣堆,20处石料堆,6处危岩体,1处不稳定斜坡,6处废弃建筑,土地损毁面积297679.41 m2,原有地质环境条件遭受了极大的破坏.为了消除矿区地质灾害、修复地形地貌景观及土地资源,基于地质工程情况,采用结构面赤平投影理论进行了分...

Exploration on geological environment characteristics and treatment and restoration of abandoned mines in Tanghe County Cement Plant

According to the investigation of abandoned marble mine in open-pit mining，there are 63 mining pits，18 high and steep slopes，3 abandoned slag piles，20 stone piles，6 dangerous rock masses，1 unstable slope，6 abandoned buildings，the land area of 297 679.41 m2 has been damaged，and the original geological environment conditions have suffered great damage.In order to eliminate geological disasters in mining area and restore landform landscape and land resources，based on the geological engineering situation，the evaluation of land is suitable for development and utilization，and the stereographic projection theory of structural plane was adopted to analyze the hidden danger of rock mass collapse and poor stability of rock slope in mine.The ecological environment of the mining area is restored by taking the measures of slope regulation engineering + topography and geomorphology regulation engineering+drainage engineering + land resource restoration engineering + ecological restoration engineering + warning engineering+monitoring engineering.To explore effective methods to restore the mine ecological geological environment，alleviate the contradiction between mining development and environmental protection，and provide basis for the protection and governance of mine geological environment.
